The New Response Alarms SAP E Completely Wirefree Passive Infra Red (PIR) detector can be easily added to your existing 433MHz response alarm system in minutes. PIR's are ideal for protecting whole areas, rooms or even outbuildings and sends a signal to activate the response alarm when an intruder is detected within the protected area.

All detectors are individually coded at the time of installation with your selected security code and no wiring is required.
