Mounting the SP818
Choosing a location
The detector is suitable for mounting indoor in dry interior locations only.
When considering a location for the detector the following points should be considered:
- Do not locate the detector facing a window or where it is exposed to or facing direct sunlight. PIR
detectors are not suitable for use in conservatories.
- Do not locate the detector where it is exposed to ventilators.
- Do not locate the detector directly above a heat source, (e.g. fire, radiator, boiler, etc).
- Do not locate the detector in a position where it is subject to excessive vibration.
Where possible, mount the detector in the corner of the room so that the logical path of an intruder would
cut across the detection zone. PIR detectors respond more effectively to movement across the detection
area than to movement directly towards the sensor.
Good Sensitivity
More Sensitive
The detector can be installed on a flat wall or in a corner as shown below.
Flat wall mounting
Mount the PIR detector at height of 2m. At this height, the detector will optimize the detection range of up
to 12m with a field of view of 90°.
Less Sensitive Bad Sensitivity
Corner mounting
This product comes with pet immunity mechanism so that small pets or animals will not trigger the
detector and cause false alarms. For pet immunity to be effective the pet's height and length must not
exceed 60cm/90cm respectively to avoid triggering the detector.
Note:
If the height of your pet exceeds 60cm, you can mount the PIR detector higher to prevent the PIR from
being triggered by your pet. For example, if your pet is 70cm tall, you can mount the detector at the
height of 2.1m instead of 2m as in regular condition, and the 70cm-tall pet should be able to stroll by
without triggering the PIR. However, the same effect would also apply to human detection. So the PIR
detector should not be mounted too high to affect its regular detection purpose.
Installation
1. Remove the rear cover if it is fixed to the main body (refer to Figure 3). Use the rear cover as a
template to mark the positions of the fixing holes on the wall. Carefully drill the required mounting
holes on the wall.
