The ST-10 door control/exit alarm was designed as an inexpensive way of controlling unlocked back-doors. It alerts you every time an unauthorized exit is being made. This self contained unit utilizes magnetic contacts that activate a continuous alarm when a door is opened and deactivates when the door is closed. An on/off switch accommodates deliveries and other controlled entries and exits.
