(Battery Operated Door Prop Alarm)

Used for door entry or exit applications, the ES300 battery operated door prop alarm can improve facility security by preventing doors from being propped or held open. This battery powered alarm has adjustable door open times from one second to four minutes, and its small size allows for a quick and simple installation.

Our ES300xMC65 includes a factory installed mortise cylinder. Units without mortise cylinder are also available, as a special order item.
