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.

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

4. SPECIAL
COMMENTS

4.1 Product Limitations

Visonic Ltd. wireless systems are very reliable and are tested to
high standards. However, due to their low transmitting power and
limited range (required by FCC and other regulatory authorities),
there are some limitations to be considered:

A. Receivers may be blocked by radio signals on or near their

operating frequencies, regardless of the code selected.

B. A receiver can only respond to one signal at a time.
C. Wireless equipment should be tested regularly to determine

whether there are sources of interference and to protect
against faults.

D. Even the most sophisticated detectors can sometimes be

defeated or may fail to warn due to: DC power failure /
improper connection, malicious masking of the lens,
tampering with the optical system, decreased sensitivity in
ambient temperatures near that of the human body and
unexpected failure of a component part.
The above list includes the most common reasons for failure
to detect intrusion, but is by no means comprehensive. It is
therefore recommended that the detector and the entire alarm
system be checked weekly, to ensure proper performance.

E. An alarm system should not be regarded as a substitute for

insurance. Home and property owners or renters should be
prudent enough to continue insuring their lives and property,
even though they are protected by an alarm system.

4.2 Compliance with Standards

The 315 MHz version of this device complies with Part 15 of the
FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2)
This device must accept any interference received, including
interference that may cause undesired operation.

WARNING! Changes or modifications to this unit not
expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.

The digital circuit of this device has been tested and found to
comply with the limits for a Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide

reasonable protection against harmful interference in residential
installations. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference
to radio and television reception. However, there is no guarantee
that interference will not occur in a particular installation. If this
device does cause such interference, which can be verified by
turning the device off and on, the user is encouraged to eliminate
the interference by one or more of the following measures:

– Re-orient or re-locate the receiving antenna.
– Increase the distance between the device and the receiver.
– Connect the device to an outlet on a circuit different from the

one which supplies power to the receiver.

– Consult the dealer or an experienced radio/TV technician.

4.3 Frequency Allocations for
Wireless Devices in European (EU)
Countries

• 315 MHz is not allowed in any EU member state.

• 433.92 MHz has no restriction in any EU member state.

• 868.95 MHz (wide band) is allowed in all EU member states.

• 869.2625 MHz (narrow band) is not restricted in any EU

member state.

circumvented, or that the Product will prevent any death, personal and/or bodily
injury and/or damage to property resulting from burglary, robbery, fire or otherwise, or
that the Product will in all cases provide adequate warning or protection. User
understands that a properly installed and maintained alarm may only reduce the risk
of events such as burglary, robbery, and fire without warning, but it is not insurance
or a guarantee that such will not occur or that there will be no death, personal
damage and/or damage to property as a result.
