MOUNTING METHOD
•
The PIR is designed to be mounted on either a flat surface or in a
corner situation with fixing screws and plugs provided.
•
The base has knockouts, where the plastic is thinner, for mounting
purpose. Two knockouts are for surface fixing and four knockouts
are for corner fixing as shown below.
•
To mount the PIR, break through the appropriate knockout. Using
the holes as a template, drill holes in the surface, insert the wall plugs
if fixing into plaster or brick.
INSTALLATION
•
Decide on the location of the PIR and if it is to be corner or surface mounted.
•
Ensure the Test/Normal mode jumper switch (JP1) is in Test mode position by inserting the
jumper link between the left two pins of the jumper switch. This is to disable the Sleep timer and
enable the LED indicator to flash every time movement is detected.
•
Screw the base to the wall.
•
Screw the cover on.
•
Walk around the protected area noting when the LED flashes and check that the detection
coverage is adequate.
•
When you are satisfied with the detection coverage, remove the PIR, place the jumper (JP1) in
the Normal mode (put the jumper link between right 2 pins).
•
Screw the PIR back on to its base Installation is now completed.
INSTALLATION RECOMMENDATIONS
•
It is recommended to install the PIR in the following locations.
o
In a position such that an intruder would normally move across the PIR’s field of view.
o
Between 2 and 2.5m above ground for best performance.
o
In a corner to give the widest view.
o
Where its field of view will not be obstructed e.g. by curtains, ornaments etc.
o
For a small 3 to 5m room, install between 1.9 to 2m above ground.
•
Limitations
o
Do not position a PIR to look directly at a door protected by a Door Contact, this could
cause the Door Contact and PIR radio signals to be transmitted at the same instant
when entering, canceling each other out.
o
Do not install the PIR completely exposed to direct sunlight.
o
Avoid installing the PIR in areas where devices may cause rapid change of temperature
in the detection area, i.e. air conditioner, heaters, etc.
o
Avoid large obstacles in the detection area.
o
Not pointing directly at sources of heat e.g. fires or boilers, and not above radiators.
o
Avoid moving objects in the detection area i.e. curtain, wall hanging.
