Installation notes
Ceiling flush PIR occupancy switches
CEFL PIR
CEFLP PIR
CEFL PIR 10A
CEFL PIR SEALED
DANLERS ceiling flush passive infra-red occupancy switches (PIR) can
be flush mounted into suspended and plasterboard ceilings (diagram
A). They include a 2 metre connecting flex to make installation quicker
and easier.
These PIR 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.
Upon detecting movement, if the ambient light is dark enough, the
PIR switch will turn the load on. The ambient threshold can be set by
the user to between approximately 100 lux and infinite lux (photocell
inactive) via the LUX adjuster (diagram E).
If no more movement is detected within a pre-selected time, then
the PIR switch will turn the load off. This time lag can be set via the
TIME adjuster to 10 seconds, 20s, 40s, 1 minute 15 seconds, 2m30s,
5m, 10m, 20m or 40 minutes (diagram E).
CEFL PIR variants
CEFL PIR

Loading
These PIR switches can switch up to 6 amps
†
(1500W) of:
• Fluorescent lamps, high frequency or switch start
• Incandescent or mains halogen lamps
(recommended with integral safety fuse)
• Electronic or wire wound transformers.
†
The CEFL PIR 10A can switch up to 10 amps (2500W) of the above loads.
They can also switch up to:
• 1 amp (250W) of fans or most metal halide lamps.

Variants
As DANLERS design and manufacture in the UK, variants can be supplied,
coded by the following suffixes and applied in this order:
• 12V or 24V
12V or 24V (ac or dc) operation
• VF
Volt Free contacts
• GOLD or LG
Gold or Logic Gold contacts
• NC
Normally Closed contacts
• 3M
3 Metre (or other) length flex
Variant details are covered in an enclosed addendum sheet if applicable.
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).
The load switches on when nobody is present:
• Heater causing infra-red variations in a small cold room.
Consider using the CEFL PIR 2DRS, double detection version.
• Ceiling void drafts or opening sealed doors causing air movement.
Consider using the CEFL PIR XS2D, extra sealed version.
• Please contact DANLERS for further technical support.
