The 97-201 ceiling-mounted passive infrared detector (PIR) is designed for use with modern residential and commercial security systems. This device is fitted with pulse-counting circuitry and employs a pyroelectric sensor equipped with 2 elements that provide substantial immunity against false alarms due to environmental factors.
