The 9V battery needs to be replaced with a name brand, alkaline battery.

Check to see that the device has a mortise cylinder with a standard Yale cam and that the cam is properly aligned with the cam assembly that it inserts into.

The device mounts to the wall and 2 external magnetic switches need to be used.  The switches are wired in series and connected to the green terminal block on the top of the board.  The JP1 jumper wire also needs to be cut on the board.

Disarm the device by turning your key clockwise. Look on the circuit board near the sticker saying "500", there are two metal prongs with white lettering near them saying 'Mag Handing'. Short them together using something metal like a screwdriver or a key. The unit should beep 5 times.  Reinstall the device with the door open, arm by turning the key counter-clockwise and close the door. You should hear 1 chirp and then the device should start the 15 second arming delay indicated by rapid flashing of green light, followed by 3 chirps, indicating that it is armed.

The likely causes are that either:

- Your door contact is not activating when the door closes. In this case, your device will not arm if the contact wires are removed from the device.

- Electric power was applied across terminals 5 and 6. In this case, your device will still arm after the door contact wires are removed from the device.

Two possible reasons:

1. Tamper plunger is not being held back by the screw on the upper left of the front of the device:

Make sure the unit is mounted and the top left tamper screw is installed.

Check That the security plunger is engaging the security micro switch on the back of the PCB.

2. Set to auto rearm(non-extended bypass) and the magnet on the frame not aligned properly.

Isolate the device by using a jumper to simulate the door closure in inputs 5 and 6.

If your device works, then check you magnet switch continuity.

The magnetic switch is a closed contact when the door is closed and opens when the door is opened.

These two wires should be connected to terminals 5 & 6.

The unit requires hard wire power of 12/24 V AC or DC. The battery is only a back up battery and will only last about 1 to 2 weeks without the wired voltage. If the battery frequent changing, the hard wired power will need to be checked.

Note: Use name brand alkaline battery. If unit has gotten wet, it will drain the battery

Windows Vista and later operating systems with 32bit or 64 bit require a new version of TopGuard Patrol. You should download the latest version from our support website. It is recommended that you use TopGuard Patrol version 2.3.2 or later.

If you have a current software contract with Detex, call tech support at 800-729-3839 and select option 2. We can provide contract holders with an immediate download to the software.

If you have a previous version purchased from Detex, you may be eligible for the upgrade through the purchase of a software  and support contract. Visit the Guard Tour Support Center for instructions and forms.

When the battery is removed for 5 to 20 minutes, the pen enters boot mode which doesn't allow it to read tags until it is re-synced with the computer. This may be due to bad batteries, but in most cases it is removed by an employee. The use of security tape around the battery cap will minimize this manipulation.

There are two drivers for the Pen-DTU: One for 32bit operating systems and one for 64bit operating systems. When installing the driver, you should choose the one for your version of Windows. Version 2.3.3 will automatically install the proper driver. If you have version 2.3.2 and 64 bit operating system, you may need to manually install the driver.

The ability to use more than 16 tours and use tour scheduling is available with TopGuard Patrol Plus. Please contact your local distributor or Detex to discuss purchasing TopGuard Patrol Plus.

On the main TopGuard screen, select the “PenDTU” bullet point and then click on the “Configuration” button. In the Configuration screen, you can select the correct Time-Zone from the dropdown list. Finally, click on “Write” to send the configuration to the Pen-DTU.

Newer computers now have USB 3 ports as standard. Pen-DTUs with a serial number older than 00002800, are not compatible with these ports. Most new PC’s still have USB 2 ports available in which the Pen DTU should work. USB3 ports are coloured blue, where USB 2 ports are coloured black. If the problem persists after switching to a USB 2 port, please contact your local distributor or Detex as you may require a new Pen-DTU.

Windows prefers digitally signed drivers over drivers that are not digitally signed. Due to restrictions in 64 bit windows, all 64bit drivers must be digitally signed. In order to install the correct driver, you must re-install the driver manually. Go to the Windows Device Manager, find the “GCS PENDTU USB DEVICE” section then Right Click the [WDF:KMDF] driver and select “Update Driver”. Click on “Browse my computer for driver software”, then click on “Let me pick from a list of device drivers on my computer”. Click on “Have Disk” then “Browse” buttons. In the “Locate File” window, navigate to your TopGuard CD or Installation Folder and find the “USB_GCSPENDTU_DRIVER” folder, then go into the “GCSPenDtuUSB 32bit” folder. Click on “Open” then click OK. Click on Next and complete the driver update wizard.

This usually occurs when the battery has been removed from the Proxi-Pen for a period of time. Within the Configuration screen, you will see a “Last Long Power Dropout”. You must change the date and time of your computer to be the same as the Last Long Power Dropout. Once done, restart the TopGuard Patrol software. You should now be able to “Set to PC Date/Time”. Clear the Control Point Memory of the Proxi-Pen. Now change the date and time of the computer back to the current date and time. Restart the TopGuard software and “Set to PC Date/Time” once more. The Proxi-Pen should now be at the correct time.
