The SPIR-F/C/IP presence detector switch is 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 adjustable 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.
The /IP variant of these products is sealed to IP55 when used with the gasket pro-
vided.
Wiring
Warning
. This device works at mains potential. Be sure to take care when working with electricity.
1.
Make sure the load is connected and in working order.
2.
Isolate the mains supply to the circuit at the main consumer unit.
3.
Connect the controller via the terminal block. Live supply to the
L
terminal, Neutral to the
N
terminal and the load to the
LIVE OUT
terminal.
4.
Set the LUX level to maximum and the time to minimum.
5.
Switch the mains supply back on at the distribution board.
6.
The load should come on immediately.
7.
Vacate the room or remain very still and wait for the load to switch off (should take no more than 2 minutes).
8.
Check that the load switches on when movement is detected.
9.
To set the final LUX level wait until the level of natural daylight is just enough that lighting is required. Starting with the LUX control fully clock-
wise (at minimum), very slowly turn the control anti-clockwise until the lights come on. Note that when the LUX control is at maximum then the
lights will
always
come on with occupancy.
10.
Set the time required.
Installation
Wire the SPIR-F/C products 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 overleaf, at a recommended
height of 3-4m on the ceiling. Note that the lower the sensor is in-
stalled the smaller the detection range will be, subject to the pa-
rameters shown on the diagram.
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.
To maintain the IP rating the unit must not be used on ceilings with an
uneven surface.
Place the gasket (provided) between the unit and the ceiling.
The units is supplied with 2 washers to seal the screw holes.
