Motion Detector Tamper Switches Offer Inherent Safeguards

There is no use spending good money on a motion detector equipped with a tamper switch if you don’t use it. Of course, many motion detectors manufactured today do not employ tamper switches. Yet the multitude of units installed each year that do offer this added feature need to be connected properly. And this does not mean tied in series with the NC contacts of the protective loop output of the detector.

Properly connected tamper switches should be tied into a 24 hour day night zone while the general burglar alarm system is off. This is done to detect inside covert attempts to disable the motion detectors’ capabilities before the system is armed at night.
