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.
NEXT is a registered mark of Visonic Ltd.
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 trigger 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
• An optional version provides better protection for systems
compliant with DD243. After initial detection, the detector is
capable of 7 additional detections for a period of 5 minutes.
Further detection is possible only if no movement occurs during
the following 2 minutes. The detector will revert to the initial
state if there is no movement for an additional 5 minutes.
• 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
