Precautions and Warranty
Dusk Switch
DUSW with Intelligent photocell
DANLERS DUSW is IP66 rated and can be surface mounted onto an
external wall. It will switch outdoor lights on at dusk and switch them off after
a chosen time delay or when it becomes light again, repeating each day.
The light level at which the lamp will switch on and off is set by a lux adjuster.
DUSW has a new ‘intelligent’ calibration process which will remove the site
specific addition of artificial light from any decision to switch the lights on/off.”
Loading
The switch should only be connected to a 230V 50Hz AC supply. These PIR
switches can switch up to:
6 amps (1500W) of resistive loads.
6 amps (1500W) of fluorescent loads.
3 amps (750W) of electronic and wire wound transformer loads.
2 amps (500W) of CFL, 2D lamps, LED Drivers and LED lamps and fittings.
1 amp (250W) of fans
Minimum load 2W resistive, suitable for most energy saving lamps, LEDs and
emergency fittings.
Installation procedure
1. Please read these notes carefully before commencing work.
In case of doubt please consult a qualified electrician.
2. The switch should be sited such that it can receive more daylight than
artificial light. Ensure that any artificial lights are not too close to the switch or
shining into it.
3. The switch must be mounted via the four pre-formed holes only, no
additional holes should be drilled through the enclosure. The spindle must
point downwards, with room below to adjust it.
4. Make sure the power is isolated from the circuit.
5. The detector should be connected as shown in diagram D.
L - Live in, N - Neutral in, SL - Switched Line out.
6. IMPORTANT - Replace terminal cover.
7. Once the wiring has been completed and verified, switch on the supply and
test the operation.

Variants
Low voltage variants can be supplied, coded by the following suffixes:
• 12VAC
12V - (ac supply) operation
• 12VDC
12V - (dc supply) operation
• 24VAC
24V - (ac supply) operation
• 24VDC
24V - (dc supply) operation
Variants with bespoke timings can be manufactured to special order.
Trouble shooting
The lamp switches off about 1 minute after it switches on.
• Unit has not been calibrated
• Too much artificial light is entering the DUSK Switch.
The lamp switches on too early in the evening.
• Move the Lux adjuster further towards clockwise.
The lamp switches on too late in the evening.
• Move the lux adjuster further anticlockwise.
If the LED fails to illuminate (after calibration) either RED or Green and the
load switches on (after a minute), the current ambient lux is lower than the
minimum 10 Lux (at the cell) and the switch cannot be inhibited off.
• Site the DUSW in a position that sees more natural light.
