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.

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 infinite 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).
DANLERS CESF PIR units can switch up to 6 amps (1500W) of:
• Fluorescent lamps, high frequency or switch start
• Incandescent or mains halogen lamps
• Electronic or wire wound transformers.
They can also switch up to:
• 1 amp (250W) of metal halide lamps or fans.
