Installation notes
Dusk Switch
DUSW
DANLERS Dusk Switch 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
point at which the lights switch on is controlled by a Lux adjuster and
the length of time the lights remains on for is set via a Time adjuster.
Loading
The DUSW should only be connected to a 230V 50Hz ac supply.
It can switch the following loads:
• 6 amps (1500W)
Incandescent or mains halogen lamps
(recommended with integral safety fuse)
• 4 amps (1000W)
Electronic or wire wound transformers.
Fluorescent lamps (high frequency or soft start)
• 2 amps (500W)
  CompactuorescentorLEDlamps(about50lamps)

Incaseofdoubtpleaseconsultaqualiedelectrician.
2. The switch should be sited such that it can receive more daylight
thanarticiallight.Ensurethatanyarticiallightisnottoocloseto
the switch or shining directly 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
spindles must point down, with room below to adjust them.
4. The cable enters from above, either through a 20mm threaded
conduit or via the cable gland provided, in which case the cable
must be circular with a diameter of between 6 and 12mm.
5. Make sure the power is isolated from the circuit.
6. The detector should be connected as shown in diagram A

supply and test the operation.
Time and Lux set-up
The time for which the lamp will stay on for can be adjusted from
approximately 2 to 16 hours as shown in diagram B.
The LUX is best set up when the ambient light is at approximately
the level at which you wish the lights to come on at. With the external
LUX adjuster set fully clockwise to ‘-’ (Dark) wait for the DUSW switch
to turn off. Rotate the LUX adjuster slowly anticlockwise to ‘+’ (Dark
to Light), at each new position wait about 5 seconds for the DUSW to
react to the change.
