The Detex Door Prop Alarms are designed for applications where doors may be used but not held open. Available in hardwired (EAX-411) or battery (EAX-300) powered, the door prop alarm sounds when a door is left open longer than the set time and silences when the door is closed. 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. Used to prevent unauthorized entry, encourage the use of access control systems and help prevent energy loss, the door prop alarm times are field adjustable from 1 second to 4 minutes.
