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.
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

3.1 General Guidelines

3.2 Illustrated Installation Procedure

RESET:

With the battery in
place, press both tamper
switches simultaneously
and release them. The
LED at the front will flash
for about 2 minutes until
the detector stabilizes.

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 de tector’s
ID while the detector’s LED
flashes.

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.
