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.
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 breakaway 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.
