PIR occupancy switch with DSI dimming
CESRA PIR DSIP
DANLERS passive infra-red occupancy (absence detection) switches
with closed loop control (CESRA PIR DSIP) can be used to control high
frequency DSI dimmable ballasts.
These PIR switches incorporate a passive infra-red quad sensor to detect
movement of a warm body within their detection zone (diagram A) and a
photocell to monitor the ambient light level.
CESRA PIR DSIP can be mounted directly onto solid ceilings or onto
a range of different mounting boxes
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 C.
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 B. 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 innite (default
value is 0). See diagram C.
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.
CESRA PIR DSIP
has an integral DSI Power Supply Unit suitable for
use with up to 12 DSI ballasts, assuming each ballast has a constant
current output of 1mA.

Variants
CEFL PIR DSIP: PIR occupancy switch (presence detection) with DSI
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).

Installation procedure
1. Please read these notes carefully before commencing work.
In case of doubt please consult a qualied electrician.
2. POSITIONING: The CESRA PIR DSIP should be installed to achieve
correct coverage of the area, see diagram A.
Avoid locating this product
where it is exposed to drafty conditions (exposed lobbies, open ceiling
voids or near fans) or near heat sources.
3. Make sure the power is isolated from the circuit.
The PIR should be connected as shown in diagram D:
SL Switched Line out
L Live in
N Neutral in
DA - DSI control line (Polarity independant)
DA + DSI control line (Polarity independant)

5. Knockout or drill the appropriate holes on the mounting plate for attaching
the plate to the ceiling or back box (if applicable). Feed cables through
the appropriate (side or rear) entry hole (see diagram E). Screw the back
mounting plate to the ceiling or back box via the mounting holes. Wire the
cables into the sensor head block terminal. Push the sensor head onto the
mounting plate and align the side clips with the slots on the sensor heads.
Start-up mode
When the PIR is powered up, it will switch on the load for 1 minute, the load
will then switch off and the PIR will enter its Operating Mode.
Time / Run-on / Lux set up
The LUX adjuster spindle on the side of the PIR is used to regulate the automatic
daylight linked dimming function lux level (see diagram C opposite). This should
be adjusted in situ by rotating the LUX adjuster slowly anticlockwise (+ to -)
so that the desired level of brightness is achieved under the luminarie(s) being
controlled.
Once the correct level is achieved and there has been no further adjustment to
the LUX spindle,
CESR PIR DSIP will go through a 30 second delay before the
automatic closed loop control will start.
CESR PIR DSIP incorporates a xed 20 second fade rate from maximum to
the set back level.
Sensitivity
CESR PIR DSIP incorporates a sensitivity adjuster, labelled ‘SENS’, to reduce
the range of detection from 100% to 50% in 9 steps
(see diagram B opposite).
