Installing Wireless WatchOUT PIR in challenging situations:
In the following situations, rapid and significant infrared radiation changes can happen in both
PIR channels together, resulting in false alarms and therefore care should be taken.
1. Situations in which metal and/or glass objects measuring over 70cm (2'4") in height from the
ground are in the field of view of the detector (cars, metal gates, shutters, metal walls,
windows, etc.)
2. Situations in which a reflective surface on the ground larger than 1m (3'4") in diameter may
cause reflection into the detector's lens. Examples of a reflective surface on the ground are
a puddle, wet road or car park, smooth concrete or asphalt surface, swimming pool, etc.
To avoid false alarms in the above situations:
Area 1
Reduce the detection range to 1m less than the distance of the metal/glass object or possible
ground surface reflection, as follows:
1. Install the Wireless WatchOUT PIR on the supplied standard swivel bracket.
2. Reduce the detection range by sliding up the Wireless WatchOUT PCB within the detector
housing, and by tilting the detector down on the swivel bracket.
3. To reduce the required tilting angle, it is recommended to install the detector at a lower
mounting height and to use the Pet immune lens for low installations.
4. Confirm by walk-test that the Wireless WatchOUT PIR detects in Area 1, and that no
detection occurs when walking in Area 2.
NOTES:
1. Please note that any outdoor PIR detector will require reduction in range to a shorter distance than the car,
metal object or surface reflection (so that these objects won't be protected) in order to eliminate false alarms.
2. For full 15m (50') coverage in the above situations, it is highly recommended to install the wired
WatchOUT DT, the only outdoor detector with 2 PIR channels and 2 Microwave channels.
3.
Wireless WatchOUT detectors include high quality Silicon filters on the PIR sensors for blocking out white light
interferences. These filters are not intended to block infrared thermal radiation.
