Precautions and Warranty
PIR occupancy switch with DALI dimming
CEFLA PIR DALIP
DANLERS passive infra-red occupancy (absence detection) switches
with closed loop control (CEFLA PIR DALIP) can be used to control high
frequency DALI dimmable ballasts. The product can be ush mounted into
suspended and plasterboard ceilings (diagram A). It includes two 2 metre
connecting exes, one 4-core cable for the supply and one 2-core cable
for the DALI control.
These PIR switches 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.
Functions
When entering a zone of detection a momentary wall switch must be pressed
to send a signal to the PIR to switch the lights ON at maximum and start
the closed loop control to maintain the preset lux level value (LUX) between
30 and 1000 lux (default value 1000 lux). See diagram D.
NO BACKGROUND ILLUMINANCE RUN ON TIME SET: If no further
movement is detected the lights will switch OFF after the set PIR hold timer
(TIME) has expired. This time lag can be set via the TIME adjuster to 10
seconds, 20s, 40s, 80s, 2m30s, 5m, 10m, 20m or 40 minutes (default value
10 seconds). See diagram C. Alternatively, the momentary switch can be
pressed for more than 2 seconds to switch the lights OFF.
BACKGROUND ILLUMINANCE RUN ON TIME SET:If no further movement
is detected the lights will FADE to minimum after the set PIR hold timer
(TIME) has expired OR if the momentary wall switch is pressed for more
than 2 seconds. The lights will then stay at minimum until the background
hold timer (RUN ON) has expired. The RUN ON time can be set via the
RUN ON adjuster to 0, 1, 2, 5, 10, 15, 20, 30 minutes or innite (default
value is 0). See diagram D.
If the momentary wall switch is pressed for less than 2 seconds while
the background hold timer is counting down, the lights will switch ON at
maximum and start the closed loop control to maintain the set lux level value.
Loading
These PIR switches can switch up to:
6 amps (1500W) of dimmable uorescent lamps.
2 amps (500W) of CFL, LED Drivers and LED lamps and ttings.
CEFLA PIR DALIP
has an integral
DALI Power Supply Unit suitable for
use with up to 12 DALI ballasts, assuming each ballast has a constant
current output of 1mA.

Variants
CEFL PIR DALIP: PIR occupancy switch (presence detection) with
DALI daylight linked dimming (does not require a momentary (retractive
wall switch).
Troubleshooting
The load will not switch on:
• 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).
