1.2. The Passive Infrared Detector (PIR)
The detector is a high quality infrared body movement detector, which is
battery operated and communicates with the
Watchguard Sentinel Home
Alarm System
via radio frequency (RF) transmission. This detector is easy to
install, provides excellent detection sensitivity and has a long battery life (up to
3 years). This detector transmits an alarm code to the unit when a valid
movement is detected.
IMPORTANT NOTES
•
NEVER touch the pyro detector with your fingers
•
During the warm up period, (first 3 minutes after installing the batteries)
the detector will not respond to movement in front of the detector. You
must wait 3 minutes before it will respond properly.
The wire, which runs around the edge of the detector, is the antenna.
Do not
touch, remove or cut this wire
