NOTE: Avoid hot and cold air currents. Mount the unit at
least three feet from strong forced-air heaters, air
conditioners, or sources of drafts such as doors.The hot
or cold air currents may cause false alarms, since the
detector will sense a rapid change in temperature.

PIRT has optimal detection when placed so that an
intruder’s path would be directly across the detection
pattern.
