Installation Instructions

To mount the PIR alarm unit, you'll need the following tools:
• A screwdriver
• A drill (for hardwood or masonry)
The PIR alarm unit should be mounted on a ceiling between 6ft/2m and 9ft/3m
high for maximum coverage and reliability.
Do not mount the PIR on a ceiling higher than 4m, as the sensor's range will not
reach the ground, and will not be able to detect the heat of a single human body
reliably.
You could conceivably mount the alarm unit on a wall. The alarm would still work,
though the field of view isn't particularly suited to this application. Under most
circumstances, a more focused PIR sensor designed to be wall mounted would be
more appropriate for that purpose.
The PIR sensor mounts in much the same way as a cordless smoke alarm. A circular
bracket is attached to the ceiling by screws, and then the main alarm unit is
attached to this bracket.
1. First, attach the mounting bracket to a ceiling, using the supplied screws. If
mounting on to hardwood, you may need to drill guide holes. If mounting
onto masonry (brick, concrete and so on) you'll need a drill with a masonry drill
bit, and use the wall plugs included with the alarm unit.
2. Push the alarm unit onto the mounting bracket. Turn clockwise to secure in
place.
