Surface-Mount PIR Switching Sensor: Installation Guide
Features
The SS-PIR-SW-01 is a PIR-triggered switch suitable for mounting onto a back box or directly onto a solid surface. It allows
simple selection of presence or absence detection to control both lighting and nonlighting loads.
Configurable for any room occupancy style, it switches on the connected load if the area is occupied and the illuminance is
lower than the specified level (with the photocell activated). Similarly, it switches off the load if the area is unoccupied for the
set time.
In absence mode, the unit can also be operated from a mains-rated retractive wall switch.

Installation Guide
Presence Mode (Default Mode)
Out of the box, the time-out adjuster is set to 10 s, and the illuminance threshold adjuster is set to maximum (photocell
inactive). With the illuminance threshold adjuster set to maximum, the sensor will always switch on the connected load
when movement is detected. There are nine time periods available from the time-out adjuster (from 10 s to 40 min).
Multiple sensors can be connected to the same load in order to extend the detection zone (see ‘Multiple sensors’ on
page 2).
Absence Mode
With the mode selector set to absence detection mode, pressing a retractive switch connected to the sensor will switch
on the connected load. Then, if no presence is detected for the selected time period, or if the retractive switch is pressed
shortly, the load will be switched off.

Installation Notes
• Position the sensor so that the occupants of the room are normally inside the detection zone.
• Do not fix the sensor to an unstable or vibrating surface.
• Do not install the sensor within 1 m of any lighting, forced air heating, or ventilation equipment.
• Do not install several sensors in parallel near lamps that emit infrared radiation if these lamps are switched via another
PIR switch. This can cause false triggering.
• Make sure that the wires and cables are securely held within the connection terminals.
• Do not connect on a circuit with large inductive loads, as induced spikes can cause false triggering or damage the sensor.
• Protect the sensor by a 6 A MCB or fuse.
• Disconnect the sensor from the circuit before performing insulation testing of the wiring circuit.

Setup
Presence Mode
Auto on, auto off via time-out settings (no manual wall switch control). Multiple sensors can be connected to the same load
in order to
extend the detection zone (see figure in section ‘Multiple sensors’ on page 2). When used in conjunctions with
illuminance settings,
the load will only switch on if the detected light levels are below the minimum level set on the illuminance
threshold adjuster.
Absence Mode
Manual on via wall switch, auto off via time-out settings or manual off via wall switch. Single sensors only. Not for use with
multiple sensors in parallel.
Illuminance Setup
Notes: It is best to adjust the illuminance setting when the ambient light level is at the required minimum level.
For loads that should switch on regardless of ambient light levels, set the illuminance setting to maximum (photocell
inactive).
1. Set the illuminance setting to minimum and wait for the load to switch off.
2. Slowly increase the illuminance setting while waving your hand below the sensor until the connected load switches on.
Connection and Fixing
Side entry
On the sensor head and back mounting
plate, knock out the required side entry
for the conduit and/or the cables.
2b.
On the back mounting plate,
knock out the mounting holes
or predrill the pilot holes for
the screws.
1. Rear entry
On the back mounting plate,
knock out the rear entry hole
for the cable.
2a
Screw the back mounting
plate to the ceiling or back
box via the mounting holes.

Time Setup
Set the time appropriately for the usage of the area. For example, some possible settings could be:
• Offices with workers regularly walking: 20 min
• Offices with mainly desk-based workers: 40 min
• Corridors: 5 min
• Washrooms with total coverage: 10 min
• Washrooms with entry coverage only: 40 min
• 2D fittings: Not less than 20 min, due to potential lamp failure. If in doubt, contact your lamp
manufacturer.
