Wireless PowerCode Quad PIR Detector

1. FEATURES

• Employs a real quad element low-noise pyroelectric sensor

• Includes a fully supervised PowerCode transmitter

• Patented sophisticated motion analysis algorithm - True Motion

Recognition (TMR™)

• Two-position vertical adjustment for coverage pattern

• Integral swivel bracket for wall or ceiling installation

• Programmable motion event counter - ON or OFF (default)

• Front and back tamper switches for improved tamper protection

• Full stabilization achieved 30 seconds after power up

• After detection, the detector disables itself to save battery

power. It reverts to the ready state if there is no subsequent
detection throughout the following 2-minute period

Visual Indications:

LED lights for about 3 seconds upon transmission of alarm &

tamper messages and upon each 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.

within 3 seconds.

Encoding: 24-bit ID, over 16 million possible combinations.
Total Message Length: 36 bits.
Tamper Alert: Reported when a tamper event occurs and in any

subsequent message, until the tamper switch is restored.
Supervision Message: Once per 15 minutes, 60 minutes or

according to local standards.

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.
