Note the Receiver is suitable for Indoor use only. The Transmitter is rated for sheltered exterior locations.
Before fixing the products, check the distance between your desired locations can communicate first.
The product is rated to operating up to a range of 120 metres in free air. The operating range will be
reduced if the signal is transmitted through a number of walls or ceilings.
NOTE: Common barriers to avoid include mounting to any metal surface or UPVC door frames.
Avoid positioning above heat sources such as radiators, or in damp areas such as a kitchen or bathroom.
Do not expose the internal unit directly to rain or immerse in water. Do not locate either unit close to
fireplace or expose to high temperatures.
Consider which way you should aim the PIR, taking into account the range and area it can cover,
as well as what may mislead it into false triggering. Aspects to consider include avoiding heat sources
close by like A/C units or vent outlets, neighbouring traffic or pedestrians, foliage in the line of detection,
or reflectance from pools or car headlights. All of these may cause false triggering at times.
Simx Entry Alert PIR are supplied as paired devices.
This product cannot be paired with multiple Receivers or Transmitters.
SELECTING YOUR MOUNTING LOCATIONS
1. The sensor can’t detect anything which is the same temperature as their backgrounds.
For example, a car which hasn’t been running long (and is, thus, the same temperature as its
surroundings) may go unnoticed. This should, however, be unlikely.
2. Any moving heat source can trigger the sensor. For example, a moving shadow on a sunny day
may trigger the sensor, or the sun coming out from behind clouds. False triggers should be rare,
but will occasionally occur.
3. Pedestrians, animals or any other large heat source can trigger the sensor, so avoid busy pathways
or sidewalks.
Therefore, try to aim the sensor towards an evenly lit and open view with a minimum of shifting
lighting or moving objects. Ideally, the sensor should only see your driveway, and the only moving
object(s) in front of the sensor should be the car (s) or person (s) you want to detect.
Reducing the angle of detection may be desirable. This can be achieved by applying opaque adhesive
tape to parts of the PIR lens to remove detection angles.
The PIR sensor is not infallible. In particular…
