compliant with DD243. After initial detection, the detector is
capable of 6 additional detections for a period of 5 minutes.

Further detection is possible only if no movement occurs during
the following 2 minutes. The detector will revert to the initial
stateif there is no movement for 5 minutes

• Automatic

termination of walk-

test after 15 minutes

• Low current consumption

• Full temperature compensation.

• Microprocessor-controlled

temperature compensation

• Sealed chamber protects the
optical system

• White light protection

3. INSTALLATION

3.1 Installation Hints

Important! The detector is immune to 36 kg
(80 lb) animals moving on the floor or
climbing on furniture as long as the activity
takes place below 1 m (3 ft). Above the 1 m
(3 ft) height limit, the detector is immune to
18 kg (40 lb) pets, but the pet immunity will

decrease as the pet gets closer to the detector. It is therefore
recommended to select a mounting location that minimizes
potential close proximity of animals.

2 DE3638

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.

A. 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).

C. Press the tamper switch once and release it. This will

perform the reset necessary for smooth power up.

D. 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

A. Remove the front cover as shown in Figure 3.
B. Loosen the vertical adjustment screw, slide the PCB down

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

C. 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 back tamper switch (option) 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

D. Hold the base against the wall at the selected location, mark the

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

E. 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

A. Remove the front cover as shown in Figure 3.
B. Loosen the vertical adjustment screw, slide the PCB down

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

C. Punch out the large knockout in the round bulge at the top

part of the base (see Figure 6).

D. Assemble the bracket as shown in Figure 6.

Figure 6. Attaching the Bracket

E. Rotate the bracket to the desired position (see Figure 7)

but do not yet tighten the screw fully.
