Recommended mounting location
Detection area
Sensor head
• Avoid direct sunlight entering the sensor
• Do not site within 1m of forced air heating or ventilation.
• Do not fix to a vibrating surface.
• Avoid metallic objects directly in front of the sensor head.
• Do not fit to a suspended luminaire
• When installing the sensor head behind a glass /
polycarbonate diffuser will reduce the detection range by
approximately 20%.
Note:
On maximum sensitivity, the detector unit is extremely sensitive
to movement and may detect through glass, thin walls or partitions.
If this causes a problem, reduce its sensitivity using the SA-IR-PROG
Programmer.

SAFETY
The microwave radiation emitted by these units is extremely
low power. At a distance of > 50mm the power density is <6%
of the ANSI IEEE C95.1 –1991 recommended microwave
power density. At a distance of 5mm from the unit it is <84% of
recommended power density.
