3. INSTALLATION

3.1 Installation Hints

To minimize false alarms:

Do not aim at heat sources Mount on solid, stable surfaces

Do not expose to air draughts

Do not install outdoors

Prevent direct sunlight from

reaching the detector

Do not install behind

partitions

Keep wiring away from electrical

power cables

3.2 Battery Insertion

It is recommended to power up the detector and let the target
receiver “learn” the transmitter’s ID before actual installation. This
can be done only after battery installation.

1st.Remove the front cover as shown in Figure 3.

Figure 3. Cover Removal

B. Insert the battery into the battery clip - observe polarity (see

Figure 4).

3rd. Press the tamper switch once and release it. This will perform

the reset necessary for smooth power up.

4th. Put the cover on and observe the LED. It will flash until the

detector stabilizes (within about 30 seconds).

Figure 4. Inside View

3rd.Punch out the mounting knockouts at the base (for surface

mounting) or mounting knockouts at the angled sides of the
base (for corner mounting).

Attention! The unit has a special tamper switch under the PCB. As
long as the PCB is seated firmly within the base, the switch lever will
be pressed against a special break-away base segment that is
loosely connected to the base (Figure 5). Be sure to fasten the
break-away segment to the wall. If the detector unit is forcibly
removed from the wall, this segment will break away from the base,
causing the tamper switch to open. It is advisable to pierce the

anti-tamper knockouts from within the base outward, while
pressing the rear surface of the break-away segment against a
piece of wood.

Figure 5. Anti-Tamper Break-Away Base Segment

4th.Hold the base against the wall at the selected location, mark

the drilling points, drill the holes and attach the base to the
wall.

5th.Return the PCB to its place: align the ”keyhole” with the head

of the vertical adjustment screw, press the PCB against the
base, slide the PCB up and temporarily tighten the screw.

3.5 Mounting with Swivel Bracket

1st.Remove the front cover as shown in Figure 3.
2nd.Loosen the vertical adjustment screw, slide the PCB down

and remove it via the “keyhole” (see Figure 4).

3rd.Punch out the large knockout in the round bulge at the top

part of the base (see Figure 6).

4th.Assemble the bracket as shown in Figure 6.

3.3 Enrolling the Transmitter ID

Refer to the target receiver’s installation instructions and follow
the procedure given there for “teaching” the transmitter's ID. It is
much easier to carry out this operation in close proximity to the
receiver.

3.4 Mounting without Swivel Bracket

1st.Remove the front cover as shown in Figure 3.
2nd.Loosen the vertical adjustment screw, slide the PCB down

and remove it via the “keyhole” (see Figure 4).

5th.Rotate the bracket to the desired position (see Figure 7) but

do not yet tighten the screw fully.

Figure 6. Attaching the Bracket

Figure 7. Wall and Ceiling Positions of Bracket

6th.Mark the points for drilling through the two mounting holes of

the bracket. Attach the bracket to the mounting surface.

G. Tilt down or swivel the detector to face the desired direction.

Figure 8 shows the tilt/swivel possibilities.

regardless of the jumper position and then enters walk-test mode.
After 15 minutes the detector enters normal mode in which the
LED functions according to the LED control jumper position.

3.8 Vertical Adjustment

Refer to Figure 10. Loosen the vertical adjustment screw and slide
the printed circuit board up or down to obtain the desired
coverage. When done, tighten the screw well.

Figure 8. Tilt/Swivel Limits

3.6 Setting the Motion Event Counter

The location of the motion event jumper is shown in Figure 4.
Refer to Figure 9 below and mount the jumper as desired.

Figure 9. Motion Event Counter Setting Options

3.7 Setting the LED Control Jumper

ON Position: Setting the jumper as shown enables
the LED. Remember that the detector disables

itself for 2-minutes after detection!
OFF Position: Setting the jumper as shown

disables the LED.

Note: At power up or reset, the LED flashes for 30 seconds

Figure 10. Vertical Adjustment

3.9 Walk Testing

Upon battery insertion or closing of the cover (which results in
closing of the tamper switch) the detector goes into walk-test
mode and automatically exits the mode after 15 minutes.

1st. Set the motion event counter as required (see Paragraph

3.6).

2nd. Adjust the vertical angle as desired (see Paragraph 3.8).
3rd. Remount the cover and fasten the case closure screw. This

results in the resetting of the detector and the start of walk­test mode.

4th. Wait until the LED stops flashing (about 30 seconds).
5th. Walk-test the entire protected area by walking slowly across

the detector's field of view, observing the LED. Pause for 5
seconds after each detection to allow the detector to complete
its 3-transmission sequence (see Appendix A); the LED will
light for about 3 seconds.

6th. When the walk-test is completed (after 15 minutes), the

detector's setting automatically changes according to the LED
control jumper setting.

Notes:

1. The OFF setting is recommended to prevent unauthorized

people from tracing the detector’s coverage pattern.

2. If the LED is disabled, you may use the control panel’s

visual and audible indicators to verify proper function of the
detector.

Attention! To assure proper function of the detector, the
range and coverage area should be checked at least twice a
year. Furthermore, the user should be instructed to perform
a walk test at the far end of the coverage pattern to assure
an alarm signal prior to each time the alarm system is armed.

4. MISCELLANEOUS
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 transmitted signal at a

time.

C. Wireless equipment should be tested regularly to determine

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

4.2 Frequency Allocations for

Wireless Devices in European (EU)
Countries

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

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

APPENDIX A. THE VISONIC LTD. POWERCODE
SYSTEM

A-1. The PowerCode Message
Format

The PowerCode message transmitted by the DISCOVERY
QUAD MCW includes the 24-bit ID and a status report (see Fig.
A1).

messages transmitted automatically at 1 hour or 15 minute

intervals. This marker will be OFF in all other messages.

• Transmitter Type: A special marker indicates the type of
the transmitter:

n Supervised or non-supervised
n Reports or does not report restorals after alarm

The DISCOVERY QUAD MCW does not report restorals after

alarms.

• Checksum: Checksum bits at the end of the message allow
the receiver to determine whether an incoming message is
valid (error-free). This feature considerably enhances the
reliability of the wireless communication link.

Figure A1. Transmitted Data

A message includes the following data:

• Detector's ID: Any message transmitted starts with the 24-
bit ID assigned to the particular detector unit.

• Tamper / Restore: Upon removal of the unit's front cover, a
message will be transmitted with a "tamper marker" ON. If
the unit's cover is put back, a message will be transmitted
with the tamper marker OFF ("Tamper Restore").

• Alarm: Once the detector is in alarm, a message will be

transmitted with an "alarm marker" ON.

• Low Battery: A special battery condition marker is used to

report the battery status in any message. The battery is
tested once an hour and if found low, the "low battery
marker" is set to ON in all following messages.

• Supervision Message: A special "supervision message

marker", when set to ON, identifies the periodic supervision
