NEXT MCW
Wireless PowerCode Digital PIR Detector
Installation Instructions
1. INTRODUCTION
The NEXT MCW is a microprocessor-controlled wireless digital
PIR detector, designed for easy installation, free of vertical
adjustment. It features a cylindrical lens with uniform detection
sensitivity throughout its operating range, up to 12 meters (40 ft),
with wall creep zone protection.
The advanced True Motion Recognition™ algorithm
(patented) allows the NEXT MCW to distinguish between the true
motion of an intruder and any other disturbances which may
cause false alarms.
An on-board motion event jumper determines whether 1 or 2
consecutive motion events triggers an alarm.
The NEXT MCW includes the following features:
Incorporates a fully supervised PowerCode transmitter
Patented sophisticated motion analysis algorithm - True Motion
Recognition (TMR™)
Sophisticated frequency domain digital signal processing
No vertical adjustment is needed
Programmable motion event counter
After detection, the detector disarms itself to save battery
power. It rearms (reverts to the ready state) if there is no
subsequent detection throughout the following 2-minute period
Very low current consumption
Microprocessor-controlled temperature compensation
Sealed chamber protects the optical system
Front cover tamper switch.
Back tamper switch (option)
White light protection
Elegantly styled, sturdy case
