NEXT MCW

Wireless PowerCode Digital PIR Detector

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

Installation Instructions

• 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

Attention! The unit has a back tamper switch (option) under the PCB. As
long as the PCB is seated firmly within the base, the switch will be pressed
against a metal spring piece attached to the base.

Be sure to fasten the break-away segment to the wall with the screws
going through the metal spring and the break-away base segment. If

the detector is forcibly removed from the wall, this segment will break away
from the base, causing the tamper switch to open and send a tamper alarm.

With the battery in
place, press both tamper
switches simultaneous ly
and rel eas e them. The
LED at the front will flash
for about 2 minutes until
the dete ctor stabiliz es.

Note:

The de]tector transmits
a low battery signal upon
detection of low battery.

Note:

It is recommended to wait
about 1 minute before inserting
the new battery.

ENROLL: Approach the
control panel and enroll the
detector’s ID into the control
panel’s memory as shown in
the panel’s installation
manual. When required to
transmit, press both tamper
switches again and release
them.
You may enroll the detector’s
ID while the detector’s LED
flashes.
