µDim Microwave Sensors
The µDim series of miniature microwave presence detectors provide automatic control of lighting loads with optional manual control. The unit comes
complete with a selection of fixing clips, allowing unobtrusive flush mounting of the sensor head into ceiling tiles or on to solid surfaces. It has been
designed so that it can be used for ceiling mounted or wall mounted applications. As microwave radiation penetrates plastic and glass, this unit has
been specifically designed to be mounted inside a luminaire.
Three versions are available: switched, 1-10V analogue, and DALI. All of which will switch incandescent, fluorescent and compact fluorescent
lighting.
The unit detects movement using a microwave sensor and turns the load on. When an area is no longer occupied the load will switch off after an
adjustable time out period has elapsed.

SL-MW-SW µDim Microwave Switching Sensor
The SL-MW-SW miniature microwave presence detector
provides automatic control of lighting loads. The unit comes
complete with a flush-mount bracket, allowing unobtrusive
mounting of the sensor head into ceiling tiles or onto solid
surfaces. It has been designed so that it can be used for
luminaire mounted or ceiling mounted applications. As
microwave radiation penetrates plastic and glass, this unit has
been specifically designed to be mounted inside a luminaire.
The product consists of the following :
• Sensor head with integral RJ11 sensor lead
• Power supply unit
• Flush mount bracket
Presence detection: when movement is detected the load will
automatically turn on; when the area is no longer occupied the
load will automatically switch off after an adjustable time period.
1) No presence detected, daylight, lights OFF
3) Presence detected, insufficient daylight, lights ON 4) No presence detected, night time, lights OFF

Sensor head
• Avoid direct sunlight entering the sensor
• Do not site within 1m of forced air heating or ventilation.
• Do not fix to a vibrating surface.
• Avoid metallic objects directly in front of the sensor head.
• Do not fit to a suspended luminaire
• When installing the sensor head behind a glass /
polycarbonate diffuser will reduce the detection range by
approximately 20%.
Note: On maximum sensitivity, the detector unit is extremely sensitive
to movement and may detect through glass, thin walls or partitions.
If this causes a problem, reduce its sensitivity using the SA-IR-PROG
Programmer.

The product can be mounted into a flat panel of a luminaire using the flush mount bracket as shown below. If flush mounting in a panel that is
greater than 6mm thick, remove bottom of retention arms with side cutters. A 44mm diameter hole will be required in the panel to mount the
flush mount bracket.

Power supply unit
• Connect the power supply via the terminal block on the power supply unit as shown overleaf. Live supply to the L terminal,
Neutral to the N terminal and the load to the LIVE OUT (L/out) terminal.
• Connect the sensor head to the power supply unit using the RJ11 connector, ensuring it “clicks” in place.
• In the case of dimming applications, connect the D+ and D_ connections to the corresponding terminals on the luminaire
dimming ballast.
• On power up, the load should come on immediately.
• Vacate the room or remain very still and wait for the load to switch off (on the factory preset, this should take approximately
15 minutes, but the timing out period can be adjusted down to 1 minute to help speed up the setup procedure — please
see next section for details on set-up & adjustment).
• Check that the load switches on when movement is detected.
