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 (diagramA). They incorporate
a 2 meter connecting ex 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 innite 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 uorescent 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 sufxes, 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 ex
The details of these variants are covered by an enclosed addendum
installation note if applicable.
Fault nding
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.

Installation procedure
1. Please read these notes carefully before commencing work.
In case of doubt please consult a qualied electrician.
Make sure the power is isolated from the circuit.
2. CEFL PIR LR should be installed to achieve correct coverage of the
working area (diagram B).
3. The greatest energy savings will be made if the CEFL PIR LR
individually controls a set of lamps. They can be wired in parallel
but this should ideally be limited to three or less.
4. The CEFL PIR LR should be connected as:
L Live in
N Neutral in
SL Switched Line out
5. Typical wiring diagrams are shown in diagrams D and E.
6. Once the wiring has been completed and veried, switch on the
supply and test the operation.
Start-up mode
When the CEFL PIR LR is powered up, it will switch on the load for 1
minute, it will then switch off and enter its Operating Mode. If a manual
override-off switch is positioned before the CEFLPIR LR it will do this each
time it is switched back to Operating Mode.Alternatively, if the wall switch
is placed after the CEFL PIR LR it will not enter the start-up mode.
Lux set-up
Ensure that the TIME is set to the minimum when setting up the LUX
level, afterwards set the TIME to a value suitable for the application.
The LUX is best set up when the local ambient light is at approximately
the minimum desired working light level, a lux meter placed on the
working surface may help. With the LUX set fully clockwise wait for the
PIR to switch off. Rotate the LUX adjuster slowly anticlockwise (- to +),
whilst waving your hand approximately 1m below the CEFL PIR LR,
until the load switches on.
This LUX setting point can be used for other devices located where the
current lighting level is not at the desired minimum working level.
