The DSI-ES411-K1 is a Door Prop Alarm that warns you to close doors that have been propped open while avoiding larger scale false alarms.
Propped open doors can be a common problem in access control systems, but the DSI-ES411-K1 offers a unique solution. When a door has been held open longer than the preset time interval (adjustable from 0-60 seconds), a local alarm will sound to alert users to close the door. The alarm silences when the door is closed.
The DSI-ES411-K1 comes with a double bit reset/bypass keyswitch.
