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.

Each time the magnetic contact breaks, a 95dB siren sounds. The pack also contains a bright red decal that can be put up to warn people that the door is guarded by a security alarm.
