1. General Information
These instructions should be read carefully and retained for further
reference and maintenance.
2. Safety
• Before installation or maintenance, ensure the mains supply to
the PIR sensor is switched off and the circuit supply fuses
are removed or the circuit breaker turned off.
• It is recommended that a qualified electrician is consulted or employed
for the installation of this PIR sensor and that it is installed in accordance
with current IEE wiring and Building Regulations.
• Check that the total load on the circuit including when this
PIR sensor is fitted does not exceed the rating of the circuit cable,
fuse or circuit breaker.
• Secure device with 10A rated air breaker.
3. Technical Specifications
• 230V AC 50Hz
• This PIR sensor is of class II construction and must not be earthed
• Motion Detection Range: Up to 8 meters diameter
at a 3m mounting height
• Presence Detection Range: Up to an 4 metres diameter
at a 3m mounting height
• Detection Angle: 360°
• Maximum Switching Load: 2300W Halogen lighting,
500W Fluorescent lighting,
500W LED lighting, (PF>0.9),
75W Fan.
• Time ON Adjustment: 3 seconds to 18 minutes.
• Dusk Level Adjustment: Day & Night or Night-time only operation
(1 to 1000 Lux).
• Manual Override: Pulse, for approximately 6 hours
ON time max.
• Ceiling Cut-out: Requires a 75mm diameter ceiling cut-out
• IP44 Rated, suitable for restricted internal applications
• CE Compliant
• Dimensions (H x W x D): 90 x 90 x 60mm
• Multiple PIR Sensor Switching: A maximum of 8 SLFM360N PIR sensors
can be wired in parallel, to enable any
detector to turn ON all the lights connected.
The total load must not exceed the lamp
rating of a single SLFM360N unit.

4. Selecting a Location
• The motion detector has a number of detection zones, at various vertical
and horizontal angles as shown (See diagram “A”).
• The best all-round coverage is achieved with the unit mounted
at the optimum height of 3 metres.
• Careful positioning of the sensor will be required to ensure optimum
performance (see diagrams “A” & “B” detailing detection range
and direction).
• The sensor is more sensitive to movement ACROSS its field of vision
than to movement directly TOWARDS IT (see diagram “B”).
Therefore position the unit so that the sensor looks ACROSS
the likely approach path.
• Avoid positioning the sensor where there are any sources of heat
in the detection area (fans, radiators, heaters etc.) including opposite
any other light sources.
• Reflective surfaces (i.e. white-painted walls, windows) may cause
false activation.

• Ensure the mains supply is switched off and the circuit supply fuses
are removed or the circuit breaker turned off.
• An isolating switch should be installed to enable the power to be
switched ON & OFF for maintenance purposes and to activate the
manual/auto override function.
• Remove the wiring cover from the sensor by depressing the catch
on the side and lifting it clear of the twin locators opposite the catch.
• Remove both cable clamps from the sensor body by undoing the 4 cable
clamp screws.
• Mark the position of the 75mm diameter fixing hole centre, taking care
to avoid ceiling joists and other obstructions within the 75mm diameter.
• Using a pad saw or suitable hole cutter cut out a 75mm diameter hole.
• Pass the 230V 50Hz mains supply and load cables through the hole
and prepare for termination.
• Terminate the cables into the terminal block, ensuring correct polarity
is observed and that all bare conductors are sleeved (see section 6.
Connection Diagram).
