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.

DIAGRAM A (DETECTION)
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 30 lux and
1000 lux and maximum (photocell inactive) at
the PIR 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,
20 seconds, 40 seconds, 80 seconds,
2 minutes 30 seconds, 5 minutes, 10
minutes, 20 minutes or 40 minutes
(diagram B).
CESF PIR also incorporates a sensitivity
adjuster, labelled ‘SENS’, to reduce the range
and sensitivity of detection (diagram B).
INSTALLATION PROCEDURE
1. Please read these notes carefully before
commencing work.
In case of doubt please consult a qualified
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 artificial 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.
LOADING
See overleaf for loading details.
START-UP MODE
When the PIR is powered up, the PIR will
switch on the lighting load for 1 minute then
switch it off. After 2 seconds it will switch
on again if it detects movement. With TIME
set to minimum the load will stay on for 10
seconds so the detection range can be
easily assessed. If a manual override-off
switch is positioned before the 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, LUX AND SENSITIVITY 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.
Turn the SENS adjuster fully clockwise
for maximum range and sensitivity of the
person detector. Turn anti-clockwise for
reduced range and sensitivity.

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
small cold room. Reduce the sensitivity
adjuster or re-site the CESF PIR.
• Please contact DANLERS for further
technical support.
