tilt the detector by 9° to achieve similar coverage
to Figure 1 (although sensitivity will be reduced).

Step 2: Mount backplate
Note: During installation, protect the electronics
against water to avoid damage.
1. Using the template provided, drill the wall
to accept the three fixing screws and the
tamper foot cup (Figure 5).

Figure 5. Tamper foot and cup
Note: Two extra tamper feet are provided;
each has a different shaft length to allow for
different wall surfaces. You can prise off the
existing foot using a small screwdriver.
2. Remove the front cover as follows:
a. Loosen the locking screw on the front of
the cover.
b. On each side of the mounting base,
insert the opening tool into the slot and
twist to separate the cover from the
mounting base.
c. Remove the cover (the cover hinges
from the top).
3. Remove the 3 securing screws located along
the top edge of the detector assembly, and
remove the assembly from the backplate. Put
the loose back-tamper spring to one side.
4. Screw the backplate to the wall (screw
through the thin areas of plastic on the
mounting base). Make sure the tamper foot
engages correctly into the cup.
Step 3: Add/configure detector
1. Fit the batteries. Observe correct polarity:
large “+” and “–” symbols are marked on
the PCB.
2. Use the relevant Installer options at the
control unit to:
a. Learn a new radio detector (when
prompted, activate one of the tamper
switches at the detector).
b. Program the zone as required.
For further information, please refer the
Engineering Guide.
3. Remain in the Installer menu (while the cover
of the detector is off).
4. If required, use the local programming
options to configure the range or pulse count
(see “Local programming options”).
Step 4: Refit and align detector
1. Fit the back-tamper spring in place, then
secure the detector assembly to the
backplate with the 3 screws.
2. Align the detector by rotating and/or tilting
the detector assembly by hand as required.
If required, apply masking to mask areas you
do not want to monitor (see “Masking”).
If pet tolerance is needed, remove the
batteries, then use a pair of long-nose pliers
to remove the metal creep mirror (Figure 7).
Refit the batteries.
