EAX-300 Door Prop Alarm

The Detex EAX-300 Series is designed for applications where doors may be used but not held or propped open. Door open times vary from 1 second to 4 minutes (15 second default) and are field selectable. The smaller size makes installation quick and easy.

Adding a door prop alarm is a low cost, desirable solution to propped open doors. They help keep energy costs down by ensuring the doors are closed. An intelligent circuit senses the external magnet location automatically, sounding an alarm when the door has been open too long, and automatically rearms when the door has been closed again; requires no waiting for the key holder to arrive.
