12. Installation
12.1 Checking the Function of the System at the Place of Installation
Before installing the PIRs and the siren, repeat the steps described in section 11.3 with the components in
the positions where you want to install them (see “Planning your System”). Hold the components
provisionally in the intended positions, and check the detection range of the PIRs and the radio link to the
siren. If necessary, change the locations. If the system operates correctly, you can continue with the
installation.
12.2 Setting the PIR Sensors to Operating Mode
If you leave the LED operational jump link fitted (it
connects both pins), the LED behind the lens flashes
when the PIR sensor detects a warm moving body. This
is only important when you are installing the PIR. It
helps you to test the detection range at the place of
installation. If you are content with the installation, you
should remove the LED operational jump link and store
it by replacing it on one of the pins. Now the LED does
not flash, and battery power is saved.
When operating the system, you should also move the
power saver jump link from covering both pins, to
covering only one pin. The PIR will send a signal to the
siren when it is triggered, whether the system is armed
or not. Removing the power saver link provides an off-
period of approx. five minutes between two radio
signals to save battery power. If you want to test your
system, you have to wait five minutes to avoid the
effects of the off-period.
After having installed and checked the PIR
sensors, you should remove both power saving
links in the PIR sensor. Otherwise
the batteries will be discharged too quickly.
12.3 Installation of the PIR sensors
The PIRs can be fixed to the wall with self-adhesive pads
supplied or with screws. Ensure that the casing screw is at the
bottom. If screwing to a flat wall, use the two predetermined
breaking points at the top and the bottom of the back casing. If
screwing to a corner, use the two predetermined breaking
points on the right and on the left of the back casing.
Break through the holes, and use the back casing as a
template to mark the position for the fixing holes. Warning:
Before drilling, make sure that there are no electric cables
hidden in the wall. Drill the holes and use the masonry plugs
and screws supplied to fix the back casing to the wall. Clip the
PIR to the back casing and secure it with the casing screw.
When using self-adhesive pads, stick them to the back side of
the casing and press the PIRs firmly to the mounting surface.
