Data Sheet

Supervised Microwave and PIR
Patented fully supervised microwave and PIR circuitry
provides single technology coverage in the event the
microwave subsystem fails. Use the memory circuit to
force a self-test at anytime.
Anti-masking With Spray Detect
Selectable to provide a microwave supervision trouble
signal if microwave reflective material (metal, wood,
plastics) is placed within 30.5 cm (1 ft) of the
detector. IR Anti-masking feature detects objects
placed to cover the detector or sprayed on the lens
area. Anti-mask sensitivity is selectable, and Anti-mask
activation can be delayed to reduce false alarms.
Motion Monitor
Switch-selectable four or thirty day Motion Monitor
supervision timers provide the detector with the ability
to verify that there is a clear view of the protection
area and that it has not been blocked.
