Choosing the Right Alarm Detector

Select detectors based on the room type, detection range, mounting position and false-alarm risk. PIR detectors suit many standard rooms, pet-immune detectors help reduce triggers from animals, and dual-technology detectors are useful in garages, warehouses, conservatories and other challenging environments.

Detector Compatibility

Check whether the detector is wired or wireless and confirm compatibility with the alarm panel. Mounting height, coverage angle, detection range and environmental conditions should also be checked before installation.
