Gizmo Engineering AB-5 Battery Powered Alarm Box with Relay, N.O. or N.C. Input
Gizmo Engineering’s Battery Powered with Relay Alarm Box (AB-5) is an alarm box that is both battery powered and powered off of relays. The alarm box will sound the alarm when a contact is either open or closed. It is similar to the AB-1 model, but has more flexibility. One of the biggest advantages of the AB-5 is it’s extremely long-lasting battery life. If the alarm is not acknowledged after an hour it goes into a power conserving mode which limits the alarm to a duration of 6 seconds, every 30 seconds.
