Door annunciator? Or door prop alarm?

EAX-300 Surface Mount Battery Powered Door Prop Alarm


EAX-300 Black and Gray

The Detex EAX-300 Series is designed for applications where doors may be used for egress or ingress, but may not be held or propped open. Door open times from 1 second to 4 minutes (15 second default) are field selectable. Setting door open time to 0 seconds turns the door prop alarm into a door annunciator. The smaller size makes installation quick and easy. The best thing about it is it's a low cost solution to propped open doors and helps keep energy costs down by ensuring doors are closed. The alarm silences when the door is closed - you don't have to wait for the key holder to arrive.

Tech Tip     


The EAX-300 can be set to be a door annunciator, which will sound for four seconds when the door is opened, then resets when the door is closed again.


To set the EAX-300 to be a door annunciator, change switch A on the board to AR. Leave the Status Indicator at the default setting.
