green-i SPIR-PRM Wall Mounted PIR Presence Detector
Overview
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 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.
Installation & Wiring
Compatible with all BS4662 dimensions back boxes.
Remove top and bottom lugs if fitted.
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.
IMPORTANT NOTICE!
This device should be installed by a qualified electrician in accordance with
the latest edition of the IET Wiring Regulations and any applicable Building
Regulations.
KEY LEGEND :
L — LIVE IN
N — NEUTRAL
L out — LIVE OUT
Setup
- Set the LUX level thumbwheel fully clockwise.
- 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.
- Apply power—the load should come on immediately.
- Vacate the room or remain very still and wait for the load to switch off (should take no more than 2 minutes).
- Check that the load switches on when movement is detected.
- 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 clockwise then the lights will always come on with occupancy.
- 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).
- If required, select the power up delay using switch 2 (to prevent the load coming on immediately on power up).
Fault Finding
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.
