Installation notes
Ceiling Surface PIR occupancy switches
CESF PIR
DANLERS ceiling surface passive infra-red occupancy switches (CESF
PIR) can be ceiling mounted on a square pattress box (DANLERS
code: PABO).
The CESF PIR incorporates a passive infra-red quad sensor to detect
movement of a warm body within its detection zone (diagram A) and
a photocell to monitor the ambient light level.
Upon detecting movement, if the ambient light is dark enough, the
CESF 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 B).
If no more movement is detected within a pre-selected time, then
the CESF 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).
CESF PIR also incorporates a sensitivity adjuster, labelled ‘SENS’,
to reduce the range and sensitivity of detection (diagram B).
Loading
DANLERS CESF PIR units 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.
They can also switch up to:
• 1 amp (250W) of metal halide lamps or fans.

Variants
As DANLERS design and manufacture in the UK, variants can be supplied,
coded by the following sufxes 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
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 SENS adjuster is set too low.
• 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 cold small room or ceiling void
drafts, fans, or sealed doors causing air movement.
Reduce the sensitivity adjuster or consider using the CESF PIR 2D
double detection version.
• Please contact DANLERS for further technical support.

Installation procedure
1. Please read these notes carefully before commencing work.
In case of doubt please consult a qualied electrician.
2. POSITIONING: The CESF PIR should be installed to achieve correct
coverage of the area, see diagram A. If the photocell override facility
is required, the switch must be located above an area where daylight
can give greater illumination than the articial light. Avoid locating this
product where it is exposed to windy or drafty conditions (exposed
lobbies, open ceiling voids or near ventilation fans) or near heat
sources. To cover large areas CESF PIRs should be spaced in a 5
metre grid formation.
3. The greatest energy savings will be made if each CESF PIR controls
an independent set of lamps. They can be wired in parallel but this
should ideally be limited to three, see diagram D.
4. Make sure the power is isolated from the circuit.
The CESF PIR should be connected as shown in diagrams C & D:
L - Live in. N - Neutral in. SL - Switched Line out.
Start-up mode
When the CESF PIR is powered up, it will switch on the load for 1
minute, the load will then switch off and the CESF PIR will enter its
Operating Mode. If a manual override-off switch is positioned before
the CESF PIR in the circuit (diagrams C & D, note 1) it will do this
each time the wall switch is switched on. Alternatively, if the wall switch
is placed after the PIR (diagrams C & D, note 2) it will not enter the
start-up mode each time.
Time and Lux set-up
For convenience, 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, making reference to diagram B.
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
surface under the CESF PIR may help. With the LUX set fully clockwise
wait for the CESF PIR to switch off. Rotate the LUX adjuster slowly
anticlockwise (- to +), whilst waving your hand approximately 1m below
the PIR, until the load switches on.
