Installation notes
Ceiling Long Range PIR occupancy switch
CEFL PIR LR
DANLERS ceiling long range PIR occupancy switches are mains
powered (230Vac) and can be mounted into the ceiling void through a
ceiling board or within a lighting luminaire (diagram A). They incorporate
a 2 meter connecting flex to make installation quicker and easier.
They 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.
On detecting movement, if the ambient light level is not above an ambient
threshold, the PIR will switch 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 C).
If no more movement is detected within a certain time, then the PIR
will switch off the load. The time can be set via the TIME adjuster to
10 seconds, 20s, 40s, 1 minute 15s, 2m30s, 5m, 10m, 20m or 40
minutes (diagram E).
Loading limits
DANLERS CEFL PIR LR units can switch up to 6 amps (1500W) of:
• Fluorescent lamps, either high frequency of switch start
• Incandescent or mains halogen lamps
(recommended with integral safety fuse)
• Electronic or wire wound transformers.
They can also switch up to:
• 2 amps (500W) of compact fluorescent or LED lamps (typically 50 lamps)
• 1 amp (250W) of Fans.

Variants
As DANLERS design and manufacture in the UK, variants can be supplied,
coded by the following suffixes, applied in this order:
• 12V or 24V
12V and 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
The details of these variants are covered by an enclosed addendum
installation note if applicable.
Fault finding
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 diagrams.
• Person is moving unusually slowly (perhaps when testing).
The load switches on when nobody is present:
• Heating source causing IR variations
• Direct light pollution causing IR variations
• Ceiling void drafts or fans causing excessive air movement.
