The SPIR-PRM presence detector switches are designed to provide
automatic control of lighting, heating or ventilation loads. They detect
movement using a PIR sensor and turn the load on. When an area is no
longer occupied the load will switch off after an adjustable time out pe-
riod.
An internal light sensor provides additional energy saving in lighting
applications. When an area is occupied lighting is only switched on when
the level of natural light is below a preset level.
When the unit is first powered up the PIR sensor will always detect im-
mediately regardless of whether the room is occupied. A selectable
power up delay allows the installer to choose whether the load comes on
immediately when the unit is powered up or is kept off for a small time
(about 40 seconds) to allow the sensor to settle.
Wire the SPIR-PRM as in the diagram.
To switch from more than one position simply wire two or more
units in parallel to achieve two way and intermediate switching.
The detector should be sited so that the occupants of the room
fall inside the detection pattern shown below, at a recommended
height of 1.2m to 1.5m for wall sensors. Note that the higher the
sensor is installed the shorter the detection range will be.
Avoid direct sunlight entering the sensor.
Do not site within 1m of forced air heating
or ventilation.
Do not site within 1m of any lighting.
Do not fix to a vibrating surface.
