Precautions and Warranty
Ceiling flush mounted PIR absence switch
CEFLAPIR
DANLERS ceiling flush passive infra-red absence switches (CEFLAPIR)
can be flush mounted into suspended and plasterboard ceilings (diagram
A). They include a 2 metre connecting flex to make installation quicker
and easier.
CEFLAPIR switches incorporate a passive infra-red quad sensor to
detect movement of a warm body within their detection zone (diagram
B) and a photocell to monitor the ambient light level.
When entering the room, if the ambient light is dark enough, the lights
can be activated by pressing a momentary light switch for less than 2
seconds. The ambient threshold can be set by the user to between
approximately 30 lux and infinite lux (photocell inactive) via the LUX
adjuster (diagram B). If no more movement is detected within a pre-
selected time, then the CESFA PIR will switch the load off. This time lag
can be set via the TIME adjuster to 10 seconds, 20s, 40s, 1 minute 15
seconds, 2m 30s, 5m, 10m, 20m or 40 minutes (diagram B).
Pressing and holding the momentary switch (for 2 seconds or more)
(while CEFLA PIR is in its ON state) will overide the control enabling
the load to be switched OFF. This is useful when a darkened room
is required or if the user does not wish the time lag period to elapse.
Allow a minimum of 1 second to elapse after the lights have gone off before
repressing the momentary switch (allowing CEFLA PIR to reset).
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.

Troubleshooting
The load will not switch on:
• The LUX adjuster is set too low and is inhibiting the switch.
• The moving body is not emitting more IR than the background.
(Person wearing insulating clothing in a warm environment)
• Person is too far from the PIR switch, see detection diagram.
• Person is moving unusually slowly (perhaps when testing).
• Please contact DANLERS for further technical support.
