DISCOVERY PIR MCW
Wireless PowerCode PIR Detector
1. FEATURES
Includes a fully supervised PowerCode transmitter
Patented sophisticated motion analysis algorithm - True Motion
Recognition (TMR™)
Two-position vertical adjustment for coverage pattern
Integral swivel bracket for wall or ceiling installation
Programmable motion event counter - ON (default) or OFF
Front cover tamper switch
Back tamper switch (option)
Full stabilization achieved 30 seconds after power up
After detection, the detector disables itself to save battery
power. It reverts to the ready state if there is no subsequent
detection throughout the following 2-minute period.
