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. W hen an area is no
longer occupied the load will switch off after an adjustable time out period.
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 immediately 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 surf ace.

LOAD DOES NOT COME ON
Check to see if the live supply to the circuit is
good. Strap across the L and LIVE OUT terminal to turn the load on.
If the supply and wiring are good, check the
LUX level setting. Increase the LUX level setting to allow the controller to turn on at higher
ambient natural light level.
LIGHTS DO NOT GO OFF
Ensure that the area is left unoccupied for a
greater time period than the time out period set
using the switch.
Make sure that the sensor is not adjacent to
circulating air, heaters or lamps.

Setup
Switch settings
Time setting
Lux setting
1. Set the LUX level thumbwheel fully clockwise.
2. Set the time to minimum (fully anticlockwise) and set both switches to ON (0-1/2 hour range, no power up delay) according to the diagram.
3. Apply power—the load should come on immediately.
4. Vacate the room or remain very still and wait for the load to switch off (should take no more than 2 minutes).
5. Check that the load switches on when movement is detected.
6. To set the final LUX level wait until the level of natural daylight is just enough that lighting is required. Starting with the LUX thumbwheel fully
anti-clockwise. Very slowly turn the thumbwheel clockwise until the lights come on. Note that when the LUX thumbwheel is fully c lockwise then
the lights will always come on with occupancy.
7. Select the time out range using switch 1 according to the diagram. Set the time out period using the thumbwheel, fully clockwise is the maximum (either 1/2 hour or 1 hour depending on the range).
8. If required, select the power up delay using switch 2 (to prevent the load coming on immediately on power up).
