This alarm can be used for indoors or outdoors for many applications such as a perimeter alarm for detecting intruders on a boundary, driveway alarm to detect visitors, warehouses, shops or yard alarm to detect customers/deliveries or garden/shed/garage alarm to detect intruders.
Unlike the other battery operated alarms on Ebay this is adjustable to your needs. Instead of giving a small ding dong or little buzz the 85db buzzer can be easily set to sound from 1 second to 999 seconds and can be armed or disarmed by the remote controls supplied.
You can also connect an external buzzer or siren for outdoor use if required.
The kit comes with 2 x remote controls but additional remotes can also be added.
The range of detection between the detectors is 15m.
Designed for easy D.I.Y. installation. A three core cable will be required from the beams to the control box.
