DISCOVERY QUAD MCW

Wireless PowerCode Quad PIR Detector

Installation Instructions

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

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

Keep wiring away from

electrical power cables

Do not install behind partitions

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.

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

Figure 3. Cover Removal

2. Insert the battery into the battery clip - observe polarity (see
Figure 4).

3. Press the tamper switch once and release it. This will
perform the reset necessary for smooth power up.

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

detector stabilizes (within about 30 seconds).

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

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

2. Loosen the vertical adjustment screw, slide the PCB down

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

Figure 4. Inside View

3.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

4. Hold the base against the wall at the selected location, mark
the drilling points, drill the holes and attach the base to the wall.

5. 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

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

2. Loosen the vertical adjustment screw, slide the PCB down
and remove it via the “keyhole” (see Figure 4).

3. Punch out the large knockout in the round bulge at the top
part of the base (see Figure 6).

4. Assemble the bracket as shown in Figure 6.

Figure 6. Attaching the Bracket

5. Rotate the bracket to the desired position (see Figure 7)
but do not yet tighten the screw fully.
