Motion Monitor
The wall mount DS308EA Quad PIR Detector uses Q-map
signal processing and a four-element (Quad), dual opposed
sensor design to provide excellent catch performance with
freedom from false alarms. The Anti-masking feature can
detect a cover-up or an intentional or accidental blocking
by sending a trouble signal to the panel. Test features,
including Motion Monitor, provide coverage integrity.
Functions
Anti-mask with Spray Detect
PIR Anti-mask feature detects objects placed over the cover
of the detector or sprayed on the lens area. Anti-mask
sensitivity is selectable, and anti-mask activation can be
delayed to reduce false alarms.
Q-map Signal Processing
Analyzes the signals from each channel to eliminate false
alarms. The horizontally opposed signals must match with
specific timing, amplitude, and signatures to cause an
alarm. Q-map adjusts for small targets that cause signals in
one channel but not the adjacent, opposing channel. This
reduces false alarms from small targets such as rodents,
while maintaining catch performance of human-sized
targets.
Test Features
•
LED flashes to indicate a trouble condition. Dual
channel internal noise voltage test pins use standard
analog meter to provide precise pattern location and
background disturbance evaluation.
•
Remote Walk Test Control: The walk test LED can be
activated remotely through a control panel command.
Temperature Compensation
Automatically monitors the ambient temperature and
adjusts the Signal processing to maintain proper catch
performance at critical temperature ranges.
Alarm Memory
Provides indication of stored alarms. Controlled by a
switched voltage from the control panel.
