The ES300 Series Battery Powered Door Prop Alarm by Designed Security Inc. (DSI) is a solution intended for use on low risk emergency exit only doors. Ideal settings include doors leading to stockroom from sales floor, stairwell doors, and various internal doors at healthcare and educational facilities.
Featuring field selectable door open times from one second to two minutes, the ES300 helps prevent secure doors from being propped open to avoid a security breach in the access control system. Built in Texas, the battery powered ES300 can also be used as a door annunciator by changing the field adjustable timer to zero seconds.
DSI also offers pushbuttons, key switches, tailgate detection, and mantrap systems.
