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.

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.
Detection of changes in infrared energy depends on the
amount of infrared energy transmitted by the moving object,
and the temperature difference between the object and the
background. Because of this the PIR may fail to respond
under certain temperature and background conditions, in
which the temperature difference is too small.
B. The DISC MCW is extremely immune to air turbulence and
RFl interference.
However, to minimize possible
false alarms, it is highly
recommended that you avoid
aiming the detector at heaters,
sources of light, or windows
subjected to direct sunlight.
Avoid mounting the DISC MCW
in locations where air drafts
could flow from the ceiling or
from close walls. Also avoid
running wiring close to high
power electrical cables.
COVER
BASE
Figure 3 - Removing the
Cover
C. Hold the unit base as shown in Figure 3. Rotate the cover
counter clockwise until it stops. Separate the cover from the
base.
Note: If the cover does not separate easily from the base,
insert a 1/8" screwdriver between a tab (on the cover) and a
slot (on the base). Lower the screwdriver handle until the base
separates from the cover and removes easily.
D. Mount the base (equipped with the
printed circuit board) in the
location selected for optimum
coverage. Using the two mounting
holes at the back of the base
fasten the unit firmly to the
mounting surface to avoid
possible vibrations. (Figure 4).
Line up the 3 tabs on the cover
with the 3 slots on the base. Fit
the cover over the base. Rotate
the cover clockwise until it stops.
Figure 4 – Installing the
Cover
3.2 LED Functions
After battery insertion and rear cover closure, the LED flashes for
2 minutes approximately until the detector stabilizes.
After stabilization, the detector enters automatically walk-test
period of 15 minutes (see section 3.6 Walk Test below). In this
mode the LED lights and the unit sends an RF alarm signal on
every detection (regardless of LED jumper position).
After the walk-test period, the LED operates according to the LED
jumper setting, as follows:
LED
Jumper
Position
LED Activity in "Normal Mode"
ON LED lights during alarm transmission.
OFF LED does not light during alarm transmission.
After the first 15 minutes, following every motion detection and
alert transmission, the detector disarms itself to save battery
power. It rearms (reverts to the ready state) if there is no
subsequent detection during the following 2-minute period.
Therefore, if you want to check the detector, you have to exit the
room for at least 2 minutes and then enter the room.
3.3 Battery Insertion
Insert battery (see Figure 5) – Verify proper polarity.
Caution!
Dispose of used battery according to manufacturer's instructions
3.4 Setting the Pulse Counter
The DISC MCW is equipped with a selectable alternate polarity pulse
counter which can be set to count two consecutive pulses with
opposite polarity, before activating the alarm relay. Pulse count signal
processing requires that the moving person will cross both elements
of the dual detector before the alarm relay is activated.
This provides maximum protection against false alarms caused by
environmental disturbances.

The two pulse logic may be selected only when the DISC MCW is
installed in temperature controlled locations.
1 pulse setting
This setting actually disables the pulse counter. It should be used
when maximum detecting sensitivity or fast "catch" performance are
of highest importance, such as in high security installations.
3.5 Enrolling
In order that the PowerMax family control panels will identify the
detector signal, perform enrolling as described in the PowerMax+
or PowerMax Pro installer guide, respectively.
3.6 Walk-Test
After closing the cover and after the detector stabilization period
(2 minutes approximately), the detector enters a 15 minute walk-
test mode. In this mode, the LED flashes each time a motion is
detected, regardless of LED jumper settings and the detector
transmits the occurrence of each event.
Walk across the far end of the coverage pattern in both
directions. The indicator should light for 3 seconds approximately
each time your motion is detected.
Important: Instruct the user to perform walk-test at least
once a week to assure proper detector's function.

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.
