The 4-1-1 On Hinges

There are four basic types of standard hinges: full mortise, half mortise, full surface and half surface.

The Four Types of Hinges

The full mortise hinge is the most frequently used type of hinge today. It can be used on aluminum, hollow metal and wood doors and frames. It was formerly referred to as a “butt hinge” because the two leaves of the hinge are pressed together when the hinge is closed. It is used for medium to heavy weight doors that are subjected to low to high frequency use. When the door is closed, the barrel is the only part of the hinge that is visible.

The half mortise hinge is generally used on hollow metal doors with channel iron frames that experience medium to high frequency use.

An illustration showing how a full surface hinge works with a door frame and door

The full surface hinge is for medium weight tubular steel doors and kalamein wood doors with channel iron frames under medium to high frequency service

An illustration showing how a half surface hinge works with a door frame and door

The half surface hinge is for regular weight hollow metal or wood composite doors with hollow metal frames that see medium to high frequency use.

Special Hinges

There are also some special types of hinges sometimes used with emergency exit doors. One of these is the continuous hinge, also called a continuous geared hinge or a traditional piano hinge. This hinge distributes the weight of the door along the full height of the door frame, and allows smooth operation and longer life for the door opening. Continuous hinges are great options on all openings, but especially high-use doors. And adding full length continuous hinges to exterior doors means that an intruder must cut the hinge the entire length of the door, which, while possible, requires much more time and effort.

Another special type of hinge is the swing clear hinge. Swing clear hinges are generally used on ADA swing doors, since they are designed to swing completely clear of the frame when opened, which creates a wider opening for maximum access.

electric hinge

An electric hinge is a special type of hinge that allows electrical current to pass from a door frame to a door. This allows the use of electronic hardware on doors, such as electric locks, electrified exit devices, access control systems, or monitoring devices without use of visible wiring.

There are also specific hinges for security applications of emergency exit doors.

Choosing A Hinge

There are a few factors that should be considered when choosing which type of hinge should be used, including the weight of the door, the frequency of use and the environment. Obviously, the correct choice of hinge depends on the application.

Interior doors usually have two hinges, while heavier exterior doors usually have three.

Concealed hinges are used when the design mandates that the hinge not be visible. A knuckle hinge is the exact opposite of a concealed hinge, in that it is intended to be seen and admired.

High-use doors, such as employee entrances and main entrances, might require heavy weight, ball bearing hinges in a finish that can endure the weather and elements. Bearings offer the highest levels of durability and ease of operation.

Medium-use doors, such as trash removal or receiving doors, might require a medium weight, standard 5-knuckle hinge in a durable finish.

Light-duty doors, such as emergency exit doors, may require three or even four hinges.

To help ensure the door provides trouble free operation, the height, width and weight of the door should be considered when choosing the type of hinge and the number of hinges.

The Importance of Door Hardware Maintenance

Door hardware plays a vital role in the safety, security, and functionality of any building. Whether it’s a school, office, hospital, or retail space, well-maintained door hardware ensures smooth operation, enhances security, and prolongs the life of your investment.

Understanding Power Transfers: A Guide to Wiring Electrified Doors

When it comes to electrified locks and exit devices, power transfers play a crucial role in ensuring seamless operation while maintaining security and aesthetics. Whether you’re planning new construction or retrofitting existing doors, selecting the right power transfer solution can make all the difference.

What Are Power Transfers?

Power transfers provide a means of running wires from the door frame to electrified door hardware such as locks, strikes, or exit devices. They come in various forms, each suited to specific applications and installation requirements.

Types of Power Transfers

  1. Surface-Mounted Power Transfers
    • Includes armored door cords or door loops.
    • Economical and easy to install on existing openings.
    • Ideal for field preparation in both retrofits and new construction.
    • Highly visible but durable, making them a practical choice for many applications.
  2. Concealed Power Transfers
    • Mortised into the door and frame for a clean, tamper-resistant installation.
    • Factory-prepared and approved for fire-rated openings.
    • Best for heavy-traffic environments or areas requiring higher security.
  3. Electric Hinges
    • Provide a concealed and vandal-resistant method of running wires.
    • Fit into standard 4-1/2″ or 5″ hinge preparations with minor modifications for wire clearance.
    • Recommended for the center hinge position for optimal performance.
  4. Wireless Power Transfers
    • Use radio frequency (RF) transmitters to wirelessly transfer energy across the door gap.
    • Eliminate the need for drilling or conduit installation, making them ideal for retrofits, especially with wood doors.
    • Capable of transferring power and signals, including latch bolt monitoring and request-to-exit (REX) signals.

When Are Conduits Needed?

  • For electrical locks and strikes, a conduit or raceway is often recommended to run wires from the hinge-side preparation to the lock or strike preparation.
  • With electrical panic devices, most connections are through the hinge-side mounting, and no conduit is typically required in the door.

Benefits of Power Transfers

  • Aesthetic Appeal: Concealed power transfers maintain a clean look by hiding wires.
  • Durability: Heavy-duty options are designed to withstand frequent use in high-traffic areas.
  • Security: Concealed solutions reduce the risk of tampering or vandalism.

5 Tips to Mitigate Campus Security Threats

Our world is full of threats both external and internal. This whitepaper encourages looking at life safety and security measures on your campus from another perspective. Most facilities have addressed access control and the securing of main doors, but those should be measures of last resort. There are steps you can take — some that you may not have considered — to mitigate the threat before it arrives at your front door.

But the threat isn’t always external. What about the daily safety of your students and staff? Measures to alert security personnel when unauthorized access or egress is about to occur can be put in place to prevent an incident before it happens.

Supplemental security measures, such as securing perimeter entrances and installing devices to warn when secondary entry points are compromised, can increase your ability to protect your campus against threats.

Prevention is the key

The questions facing the person responsible for campus safety and security are numerous. How do you allow authorized staff to move freely through your facility, accessing areas that are restricted to the general public, but still allow egress during an emergency? Are you vulnerable to an attack from a disgruntled staff member, begrudged student, or stranger off the street? How effective is your access control system if staff or students are propping doors open? Can we put controls in place, but still meet ADA requirements?

We give these threats little thought until the unthinkable is broadcast on national news and then we scramble to ensure our faculty and students are not exposed to such a threat.

Examining security and safety on your campus from a holistic viewpoint can help prevent these threats from materializing. Enhance life safety and security measures on your campus with the addition of cutting-edge technology that works in conjunction with your existing systems, such as:

  1. Delayed egress devices with alarms
  2. Perimeter fencing emergency exit and access control
  3. Door prop alarms
  4. Tailgate detection systems and alarms
  5. Lockdown systems

1) Delayed egress devices

Delayed egress devices in education facilities can protect lives. Check your local fire and safety codes before installing delayed egress equipment. By installing delayed egress exit devices, you can:

  • prevent unauthorized exit through secured openings.
  • re-direct foot traffic to a specific corridor that is monitored by security personnel.
  • combine them with electric latch retraction and automatic door operators for access control, which will allow staff to move freely throughout the facility while controlling visitor and student foot traffic.
Weatherized delayed egress prevents potential threats before they can even enter your property.

2) Perimeter emergency exit and access control

Playgrounds with emergency exit gates that open near a busy street can be cause for concern. Where life safety codes restrict traditional locking of these gates, weatherized delayed egress may be an acceptable application, depending on the authority having jurisdiction. Weatherized delayed egress systems:

  • include panic hardware that emits a loud local alarm, encouraging a student to move away from the area while alerting staff that someone is attempting to exit through the gate.
  • provide staff time to react before the gate unlocks and helps to avoid a dangerous situation.
  • feature access control that prohibits unauthorized entry.
  • are tied into a fire alarm override, providing safe, undelayed exit during a fire emergency.

3) Door prop alarms

Supplementing existing door security with door prop alarms helps maintain a more secure environment. A door left propped open, even for a few seconds, can provide an easy access point for threats. Door prop alarm hardware will:

  • alert personnel to an unsecure door via audible alarm.
  • send an alert to any central security monitor.
  • help prevent unauthorized personnel from entering the premises.

Tailgate detection systems limit access to a single authorized user.

4) Tailgate detection technology

Access control systems and temporary visitor badges have become common in most school districts. However, regardless of the campus size, tailgate detection technology can be used to control access, allowing only authorized personnel access to to restricted areas. Tailgate detection systems will:

  • sound an alarm if someone attempts to follow an authorized employee through a secure door.
  • help secure areas that may contain sensitive material, expensive equipment, or personnel or student records.
Help prevent the unthinkable from happening. Electric dogging provides uncomplicated, instant lockdown to a campus threat.

5) Lockdown Systems

What is the safest, fastest, easiest and most cost effective means of locking down your campus? There are many answers; however, one way that has been overlooked by many security door consultants is the use of panic exit devices with electric dogging. When installed throughout a school facility, electric dogging allows all locking devices to be “energized” by one control switch that can be located in a centralized area of the building. Electric dogging:

  • keeps doors in push / pull configuration.
  • can be activated from one of several switches located throughout the campus to lock main doors in case of a required lockdown.
  • provides additional security when electricity is removed by reverting to secure mode, effectively preventing entry at every door equipped with this type of device.

(Be aware that add-on mechanical options like hex or cylinder dogging may jeopardize the effectiveness of the lockdown system.)

Electric dogging is different than electric latch retraction. With latch retraction, applying power pulls the latch(s) back and holds them until power is removed. With electric dogging, after applying power a user must manually depress the pushpad to retract the latch(s). The latches stay retracted until power is removed from the device.

When electric dogging is applied to entry doors, it removes the need for a staff member, perhaps in the height of a crisis, to remember where the key is and how to lockdown the doors. The administrator, taking the responsibility off the shoulders of the education staff, makes the decision and takes action to lockdown. Electric dogging can:

  • allow doors to be dogged for push / pull operation during a specific hours.
  • automatically revert to secure mode at a pre-selected time, locking the doors to entry, but individuals leaving are still allowed to exit.

Put all the right pieces in one place for complete peace of mind.

Ensuring all the pieces of technology will work together is key. Manufacturers and some dealers will create a kit to fit your application that includes best-in class products along with wiring and riser illustrations to fit your application. Be careful of specification writers who supply only a list of products without a wiring diagram or information on how the items are integrated together. Failing to install the items correctly can create years of headaches and wasted money. Ensure the supplier understands your needs and offers time-tested products. Additionally, make sure they can support the installation with wiring diagrams, riser illustrations and technical support.

The Basics of Break-In Prevention: Securing Your Facility

No facility is completely impervious to break-ins, but with the right security measures in place, you can make it much harder for burglars to succeed. The goal of break-in prevention is not to guarantee a completely secure building but to delay unauthorized entry long enough for law enforcement or security personnel to respond. Even if your building hasn’t experienced any recent security threats, regular evaluations and upgrades to its protective measures are essential.

Here’s a back-to-basics guide on how to fortify your facility’s entry points and deter potential break-ins.

1. Start with a Heavy-Duty Door

The foundation of a secure entry point starts with the door itself. Even the strongest locks and security features will be ineffective if the door is weak.

  • Material Matters: Choose a door made of thicker material—16-gauge steel doors and frames are significantly stronger and more resistant to break-ins than their 20-gauge counterparts.
  • Reinforcement: Your door should be reinforced to properly support security hardware like locks and bolts. Be sure to consult with a door security distributor or integrator to ensure compatibility and durability.

2. Use a Full-Length Hinge

In commercial settings, doors must swing outward to comply with egress codes, leaving the hinge knuckles exposed and vulnerable.

  • Why Full-Length Hinges?
    • Support: Full-length hinges provide better support for heavy-duty doors compared to standard discrete hinges.
    • Resistance to Tampering: Continuous hinges are much more difficult for potential intruders to manipulate or vandalize. Upgrading to a full-length hinge significantly boosts your door security.

3. Invest in High-Strength Locks

The lock is your first line of defense, so its strength should never be overlooked.

  • Pull Force Resistance: Choose locks that can withstand at least 10,000 pounds of pull force.
  • Deep Bolt Penetration: Ensure your locks have deep bolt penetration into the door frame for maximum security.
  • Floor Bolts: Adding a bolt that locks into the floor helps prevent burglars from prying the bottom of the door upward, a common tactic used in break-ins.

4. Install a Burglar Alarm

A robust alarm system can be a strong deterrent against intruders. Alarms alert authorities and make your facility a less attractive target. When paired with strong door hardware, alarms create a multi-layered security approach that is both proactive and responsive.

Layering Security for Maximum Effect

The most effective security comes from combining these elements:

  • Heavy-duty doors
  • Full-length hinges
  • High-strength locks
  • Alarm systems

Together, these components work to:

  • Delay or prevent unauthorized access
  • Deter intruders from targeting your facility

Conclusion

Break-in prevention is all about implementing strong, well-maintained hardware and a layered approach to security. Even small upgrades, like replacing standard hinges with full-length ones or adding a floor bolt, can greatly enhance the safety of your building.

Panic Exit Devices vs. Fire-Rated Exit Devices: What’s the Difference?

Exit devices play a crucial role in ensuring safety during emergencies, but not all are created equal. While panic exit devices and fire-rated exit devices may look similar, their purposes and applications differ significantly. Understanding these distinctions is key to selecting the right hardware for your building’s needs.

advantex 10 series rim device / request to exit device / latch bolt monitor

What Are Panic Exit Devices?

Panic exit devices, often called crash bars, push bars, or simply exit devices, are designed to allow quick and easy egress during emergencies. They operate by releasing a latch when pressure is applied to a horizontal bar or pad in the direction of exit travel.

Key Features:

  • Ease of Use: The device unlocks the door with minimal force (15 pounds or less).
  • Coverage: The push bar or pad must extend at least half the width of the door.
  • Application: Required by the International Building Code (IBC) for certain buildings, including:
    • Educational and assembly facilities.
    • High-hazard occupancies.
    • Electrical or battery rooms.
  • Relocking: While panic exit devices can re-latch when the door closes, re-latching is not mandatory.

Purpose:

Panic exit devices prioritize speed and simplicity, enabling occupants to exit safely during emergencies, such as a fire or other life-threatening situations.

fire rated exit control lock

What Are Fire-Rated Exit Devices?

Fire-rated exit devices serve a dual purpose: providing quick egress while also maintaining the integrity of a fire-rated door assembly. These devices are designed for doors that help compartmentalize a fire, slowing its spread and allowing more time for evacuation and emergency response.

Key Features:

  • Fire-Rated Doors: Used on doors within fire-rated walls, such as:
    • Stairwell doors.
    • Doors to common hallways.
    • Doors within separation walls.
  • Re-Latching: Fire-rated exit devices must re-latch automatically when the door closes, ensuring the door remains securely closed during a fire.
  • Industry Testing: These devices must pass rigorous testing to confirm they can secure the door during a fire.
  • Time Rating: Must bear a label indicating the fire rating, typically ranging from 20 minutes to 3 hours.
  • No Mechanical Dogging: Fire-rated devices cannot be mechanically dogged (held in the open position), though electric dogging is permitted.

Purpose:

Fire-rated exit devices are critical for life safety and property protection, ensuring that fire-rated doors perform as intended to contain fire and smoke.

Key Differences Between Panic and Fire-Rated Exit Devices

FeaturePanic Exit DevicesFire-Rated Exit Devices
Re-LatchingOptionalMandatory
Fire ResistanceNot requiredMust pass fire-resistance testing
Mechanical DoggingAllowedNot allowed (electric dogging permitted)
Fire-Rated DoorsNot requiredRequired
ApplicationsGeneral emergency exitsFire-rated door assemblies

Choosing the Right Device

When selecting exit hardware, consider the specific requirements of your building and its safety codes:

  • Use Panic Exit Devices for doors in educational facilities, assembly spaces, or high-hazard areas where quick egress is the primary concern.
  • Use Fire-Rated Exit Devices for doors within fire-rated walls, such as stairwells and hallway separation doors, where fire containment is crucial.

Keep in mind that all fire-rated exit devices are also panic exit devices, but not all panic devices meet fire-rating requirements.

Conclusion

Understanding the difference between panic exit devices and fire-rated exit devices ensures that your building is both safe and compliant. By selecting the right hardware for each door, you can protect occupants, preserve property, and meet building code requirements.

Understanding Automatic Operators and the “Knowing Act”

Automatic door operators play a vital role in providing accessible, convenient, and secure building entrances. Whether you’re retrofitting an existing door or planning for a new installation, understanding the differences between operator types and the importance of the “Knowing Act” is essential for compliance and safety.

Types of Automatic Operators

Automatic operators generally fall into two categories:

  1. Low-Energy Operators
    • Purpose: Ideal for mixed-use doors that some users open manually while others activate automatically.
    • Standard: Governed by ANSI 156.19, which limits the speed and force of operation to ensure safety.
    • Activation: Requires a Knowing Act, where users consciously trigger the door using push buttons, touchless switches, card readers, or similar devices.
    • Applications: Common in schools, libraries, hospitals, and entrances designed for ADA compliance.
  2. Full-Energy Operators
    • Purpose: Designed for high-traffic areas where doors open and close quickly.
    • Standard: Governed by ANSI 156.10, which includes stricter safety measures like sensors and guard rails.
    • Activation: Triggered by motion sensors that detect movement near the door.
    • Applications: Grocery stores, retail outlets, and environments requiring rapid door movement.

The Knowing Act: Key to Low-Energy Operators

Low-energy operators must be activated by a “Knowing Act,” meaning the user makes a deliberate effort to trigger the door. This activation method not only complies with ADA standards but also limits potential risks by ensuring users are aware of the door’s operation.

4-1/2 inch square push plate for automatic operators

Common Knowing Act Devices:

  • Push Buttons: Available in various sizes and shapes, these can be mounted on walls, jambs, or bollards for easy accessibility.
  • Touchless Switches: Hands-free solutions that enhance hygiene and convenience.
  • Card Readers & Keypads: Ideal for secure facilities, providing both access control and activation.

Installation Guidelines for Knowing Act Devices

To ensure compliance with standards like ADA, ANSI 156.19, and ICC A117.1, follow these installation tips:

  • Mount the actuator within 1-12 feet of the door.
  • Position the device so users are not in the swing path of the door.
  • Ensure a clear floor space is available for wheelchair users, beyond the arc of the door swing.
  • Actuators must operate without requiring tight grasping, pinching, or twisting and should require a maximum force of 5 lbs.

Why Not Use Motion Sensors for Low-Energy Operators?

Adding motion sensors to a low-energy operator changes its classification to a full-energy opening under ANSI 156.10, which requires enhanced safety measures such as sensors and guard rails. These additions increase both the cost and complexity of the system, making Knowing Act devices a more practical solution for many applications.

Selecting the Right Operator for Your Needs

When choosing between low-energy and full-energy operators, consider the traffic flow, safety requirements, and compliance needs of your facility. For most ADA-compliant entrances, low-energy operators activated by a Knowing Act are sufficient, offering an accessible, cost-effective solution without compromising safety.

By understanding the nuances of automatic operators and their activation methods, you can ensure your building meets regulatory requirements while providing a seamless experience for users.

Understanding Windstorm-Rated Hardware: Protection Against Nature’s Fury

windstorm icon

When it comes to safeguarding buildings and their occupants from extreme weather events like hurricanes and tornadoes, windstorm-rated hardware plays a crucial role. These specialized components are designed to protect against high-velocity winds and dangerous debris while maintaining structural integrity and functionality. Let’s explore the key distinctions and requirements for hurricane-rated and tornado-rated hardware.

Hurricane-Rated Hardware: Built for Sustained Storms

Hurricanes are among the most devastating natural disasters, with an average of 12 forming in the Atlantic basin each year. While storm surges are often the deadliest aspect, windborne debris accounts for much of the structural damage.

Hurricane-rated hardware is specifically designed to:

  • Prevent Debris Penetration: Protect buildings from windborne projectiles while maintaining the integrity of doors and their components.
  • Withstand High Velocity Hurricane Zones (HVHZ): Tested to endure sustained wind pressure and extreme conditions over long periods.

Guidelines and Testing

Hurricane-rated hardware must comply with the Florida Building Code (FBC), which sets stringent standards. Many coastal states adopt the FBC for their hurricane door requirements. Hardware is subjected to rigorous third-party testing, including:

  • Static Pressure Testing: Ensures hardware can withstand sustained wind pressure.
  • Debris Impact Testing: Verifies resistance to high-velocity projectiles.
  • Cyclical Pressure Testing: Simulates the stress of repeated wind gusts.

To meet FBC standards, all components—doors, frames, hinges, and exit devices—must bear visible windstorm rating labels. Importantly, the FBC recognizes component listings, allowing substitutions of products with equivalent ratings.

Tornado-Rated Hardware: Protecting Lives in an Instant

Tornadoes, while shorter in duration, are among the most violent natural events, with wind speeds reaching up to 250 miles per hour. In the U.S. alone, an average of 1,000 tornadoes are reported annually, making tornado-rated hardware vital in vulnerable regions.

The primary purpose of tornado-rated hardware is to:

  • Protect Occupants: Prevent extreme pressure differentials and block projectile debris.
  • Withstand Extreme Winds: Maintain integrity under short bursts of intense force.

Guidelines and Testing

Tornado-rated hardware adheres to FEMA 361 and ICC 500 standards, which outline stringent safety measures for tornado shelters. These products undergo comprehensive testing by third-party laboratories, including:

  • Static Pressure Testing: Ensures durability against extreme pressure differentials.
  • Impact Testing: Confirms resilience to debris impacts at speeds up to 100 miles per hour.

Unlike hurricane-rated systems, tornado-rated hardware is tested and certified as an assembly. This means the door, frame, and hardware must be supplied and installed together as a single unit to maintain compliance.

Key Differences Between Hurricane- and Tornado-Rated Hardware

FeatureHurricane-Rated HardwareTornado-Rated Hardware
PurposeLong-term protection from sustained winds and debris.Short-term protection from extreme winds and debris.
StandardsFlorida Building Code (FBC).FEMA 361 and ICC 500.
TestingStatic pressure, debris impact, and cyclical pressure.Static pressure and 100 mph impact testing.
ApplicationCan use component listings.Must be installed as an assembly.
MaterialsVarious materials.Steel doors only for FEMA 361 compliance.

Choosing the Right Windstorm-Rated Hardware

When selecting windstorm-rated hardware, consider the specific risks in your region. Coastal areas prone to hurricanes may prioritize FBC-compliant systems, while tornado-prone regions should invest in FEMA-rated assemblies for maximum protection.

By understanding the differences between hurricane- and tornado-rated hardware, building owners and facility managers can make informed decisions to safeguard lives and property.

Understanding Grade 1 Panic Devices: What You Need to Know

If you’ve worked with door hardware, you’ve likely heard of Grade 1 panic devices. But what does “Grade 1” actually mean? More importantly, why should it matter to you or your facility?

What Do the Grades Mean?

The Builders Hardware Manufacturers Association (BHMA) establishes and maintains standards for the door hardware industry, including panic hardware. These standards ensure a consistent level of quality and performance. Panic hardware undergoes rigorous cycle tests to earn one of three grades, each reflecting its durability and reliability:

  • Grade 1: Must withstand at least 500,000 cycles
  • Grade 2: Must withstand at least 250,000 cycles
  • Grade 3: Must withstand at least 100,000 cycles

Grade 1 devices are the toughest, designed for the highest traffic and most demanding environments. Some manufacturers go above and beyond, testing their products well beyond the minimum requirements to ensure maximum durability.

What Makes Grade 1 Different?

As of the latest ANSI/BHMA standard (2020), the requirements for Grade 1 panic devices include a preloading test. This means the device is tested with a simulated real-world load before the cycle test begins.

In real-world scenarios, doors may experience additional force from:

  • Air pressure
  • Misaligned doors or frames
  • Installation issues

The preloading test applies a force equivalent to a net 20-22 pound-force (lbf) to mimic these conditions, making it more challenging for devices to pass. This ensures Grade 1 devices are not only durable but also effective under realistic conditions.

Why Does This Testing Matter?

Panic hardware must perform flawlessly in critical moments, so testing focuses on several key criteria:

  1. Operation
    The device must function consistently, whether in a lab or the field.
  2. Durability
    Grade 1 hardware is built to last, ensuring years of reliable use.
  3. Safety and Security
    These devices are tested to withstand:
    • Forced entry from the pull side.
    • Heavy push loads from the opposite side.
  4. Appearance
    Grade 1 devices resist corrosion, chemicals, and UV exposure, ensuring they maintain their finish over time.

Why Choose Grade 1 Panic Devices?

Grade 1 panic devices are ideal for high-traffic areas such as:

  • Schools and universities
  • Hospitals and healthcare facilities
  • Stadiums and arenas
  • Office buildings

Investing in Grade 1 hardware provides peace of mind, knowing that your exit devices are designed to withstand demanding conditions while maintaining the safety and security of occupants.
