2.2.9 Hard Wired External Siren
This section shows you how to install a hard wired external siren for your system.
The External Siren should be mounted at the front or the front side of the building so as to provide maximum
visual deterrent and to allow neighbours to identify that it is your system that has been activated. The
mounting position must NOT be exposed to direct rain or other water sources. This means that under an eave
or roof overhang is a good location as shown in the diagram below. The position should allow line of sight
viewing from both the street (for visual deterrent) and from your main point of entry (for visual confirmation of
arming/disarming).
Use the wall plugs and screws provided if suitable for your particular building construction.
a) Installing the COS-PLUG Siren
Unit (refer to pictures opposite)
1. Drill mounting holes (7mm diameter, 25mm minimum
in depth) into the chosen wall.
2. If a masonry wall, use the green star plugs. Press each
one into the 4 main mounting holes.
3. Make a 12mm hole and feed the 20m cable through
the wall and to the main control module.
4. Screw the top 2 screws half way in.
5. Place the unit to support itself from the top 2 screws
through the key shape holes at the top of the main
control unit
6. Screw in and tighten the bottom two mounting screws
then tighten the top two screws.
7. Now run the 10m of low voltage cable through the roof
to the closest power point.
