DISC MCW

Wireless PowerCode Digital Ceiling Mount PIR

detector

Installation Instructions

1. INTRODUCTION

The DISC MCW is the smallest 360° ceiling mounted passive

infrared detector presently marketed. The DISC MCW is a

microprocessor-controlled wireless digital PIR detector, designed

for easy installation.

The DISC MCW provides a nearly conical pattern of maximum

10.5 m (36 ft) diameter, when installed on a 3.6 m (12ft) ceiling.

The advanced True Motion Recognition™ algorithm (patented)

allows to distinguish between the true motion of an intruder and

any other disturbances which may cause false alarms.

False alarms caused by environmental disturbances are virtually

eliminated with alternate polarity pulse counter signal processing

and a low-noise pyroelectric detector.

The DISC MCW includes the following features:

• Provides multiple beams coverage.

• Incorporates a fully supervised PowerCode transmitter.

• Sophisticated frequency domain digital signal processing.

• Programmable motion event counter.

• Very low current consumption

• Tamper switch for detector opening.

• White light protection.

• Elegantly styled, sturdy case.

2. SPECIFICATIONS

Detector Type: Dual element low-noise pyroelectric sensor.

ELECTRICAL

Internal Battery: 3V Lithium battery, type CR-123A. For UL

installations, use Panasonic, Sanyo or GP only.

Nominal Battery Capacity: 1400 mA/h.

Battery Life (with LED on): Typically over 3 years.

Battery Power Test: Performed immediately upon battery

insertion and periodically after every several hours.

FUNCTIONAL

True Motion Event Verification: 2 position selector - 1 (OFF) or

2 (ON) motion events.

Visual Indications:

LED Lights for about 3 seconds upon transmission of alarm &

tamper messages and upon motion detection in the walk test

mode.

LED Flashes during the power-up stabilization period, or after

restoring (pressing) the tamper switch.

LED does not light upon transmission of supervision

messages.

Rearm Timer: Rearms the detector 2 minutes after the last motion

detection. The detector reverts to the initial state if there is no

movement during 2 minutes. The timer is disabled in the walk test

mode.

WIRELESS

Frequency (MHz): 315 (U.S. version) or other frequency according

to local requirements.

Transmission Sequence: 3 data bursts at variable / random

intervals within 3 seconds.

Encoding: Over 16 million possible combinations.

Total Message Length: 36 bits.

Supervision Message: Signaling at 60-minute intervals (U.S.

version).

MOUNTING

Ceiling Mounting: Maximum mounting height 3.6 m (12 ft)

ENVIRONMENTAL

3. INSTALLATION 3.1 Mounting The DISC MCW PIR is installed on the ceiling. The maximum installation height is 3.6m (12 ft). A. Mount the unit so that the expected motion of an intruder is perpendicular to the detector and not into the detector. Be sure to install the detector on a stable ceiling, to avoid vibrations. Note: Passive infrared detectors are sensitive to changes in infrared energy caused by an object moving across the unit's field of view.

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.
