Two-way communication PIR detector. This device is protected against dislodgement and
open-cover tamper, and allows sensitivity adjustment from remote with no direct intervention
on the detector. This device provides an option which allows you to disable the detection
LED. It also provides an option which allows you to enable device operation only when the
partition it belongs to is armed, thus greatly saving battery power. The detector is available in
two models. Air 2-IR 100 is a 12 m volumetric detector, Air 2-IR 100 C is a 20 m corridor detector.
