DISCOVERY QUAD
MCW
Wireless PowerCode Quad PIR Detector
Installation Instructions
1. FEATURES
• Employs a real quad element low-noise pyroelectric sensor
• 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 or OFF (default)
• Front and back tamper switches for improved tamper protection
• 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
• Automatic termination of
walk-test after 15 minutes
• Low current consumption
• Microprocessor-controlled
temperature compensation
• Sealed chamber protects the
optical system
• White light protection
• Elegantly styled, sturdy case
• Keyhole-shaped slot for
easy removal of PCB
