Good inexpensive alarm
I put this alarm product on an outbuilding as a door alarm, using the alarm extension as a door trigger and mounting the box next to the door. The basic electronic design allows for a number of configurations and you can use it to trip outboard visual alarms with the onboard NO/NC relay contacts. Over and above using it for alarming a secured exit door it is versatile enough to create a multi sensor basic alarm system. If you had the motivation, you could use it for a two zone home alarm system. Works as an entry alarm as well as an exit alarm.
