PIR 360° 41-302 Master/Slave Sensor
Installation and operating instructions
1. Applications.
The PIR 360º 41-302 Master/Slave Sensor is designed
to be fitted to the ceiling for indoor light control, for
example in offices.
Areas where the unit is suitable:
• Offices
• Corridors
• Staircases
• Canteens
2. Function.
Master unit:
The integrated light sensor measures the light level
in the area continuously and compares it with the
preset value specified via the LUX setting button.
The light is switched on if the light level falls below
the preset value and the movement sensor detects
activity in the coverage area. The integrated off
delay of 1-30 minutes ensures that the light stays
on until the sensor no longer detects activity or the
selected light level is reached.
Slave unit:
The movement sensor of the slave unit detects
activity in the coverage area. The integrated off
delay of 1-30 minutes ensures that the relay remains
closed until the sensor no longer detects activity.
Calculating the total off delay when using slave
units:
The off delay in the master unit is set to 15 min.
The off delay in the slave unit is set to 10 min.
Total off delay:
Master 15 min. + slave 10 min. = 25 minutes.
The shortest possible off delay is
2 minutes (master 1 min. + slave 1 min.).
If only the master unit is used, the shortest possible
off delay is 1 minute.
All slave units MUST have the same PHASE as the
master unit.
3. Installation.
Coverage area:
The PIR 360º sensor is designed to be fitted to a
ceiling. At a height of 2.5m the sensor will cover a
floor area with a diameter of 20m and provide full 360º
coverage for the movement of people.
The PIR 360º sensor has a special lens area in the
centre with a diameter of 5m, with more than 618
fields guaranteeing optimal detection of even very
slight movements.
The PIR 360º sensor is designed be fitted to ceilings
with a standard height of 2.5-3.0m and should be
located above a desk, usually 1 metre away from
the chair.
The sensor has a specially developed optical
function with two detection ranges: a close range
(A + B) to detect small movements and a distant
range (C + D) to detect body movement. This
combination provides excellent control of lighting,
while at the same time guaranteeing the greatest
possible energy saving, see Fig. 1.
Limiting the detection range:
If the coverage area is too large, it is a good idea to
limit it by fitting the enclosed cover. This reduces the
maximum coverage of Ø20 m to Ø12 m, Ø5 m or Ø3m,
and the 360º angle can be reduced by multiples of 45º,
see Fig. 2.
It is recommended that the PIR sensor is not installed
where it is exposed to direct sunlight, air flows from
air conditioning, radiators, etc., see Fig. 3.
Fitting:
a) For optimum daylight readings, the PIR 360º
sensor (master) should be fitted with the light-
gate pointing towards the incident daylight.
See Fig. 4
b)If the PIR 360º sensor is fitted directly to the
ceiling, holes at intervals of 105 mm can be used.
Please note that the cable input is turned 45º in
relation to the fixing holes, see Fig. 5.
c) If the PIR 360º sensor is fitted to flush mounting
box, use the holes provided for this purpose,
spaced 60 mm apart and punch out the base cap.
Run the cable carefully and correctly, following
the instructions for fixed installation. Note that the
main power must be switched off for any
installation work. See Fig. 5.
d)Push the sensor component into the terminal block
in the base and fit the locking screw.
e)Set up and test the PIR 360º sensor as described
in point 4 and Fig. 7.
f) The coverage area can be reduce as shown in
Fig. 2.
g) Fit the sensor cover as in Fig. 8
Connection:
a) First read ALL the installation and user instructions.
b) Switch off all power.
c)Connect the mains supply to the terminals
marked: L, N.
d)Connect the load to the terminals marked:
on the master unit
e)Connect the slave unit between SL on the master
unit and on the slave unit.
f) During the power-up period, the light and
integrated indicator (LED) always light up for 1
minute (stabilisation period).
Connect the ground to the terminal marked:
For wiring diagram, see Fig. 6
Pushbutton operation:
Option to use a pushbutton to switch on the light,
provided the light level is lower than the preset
value, see Fig. 9
Changing the master unit into a slave unit:
Turn LUX to Max.
Change lightgate (transparent) to lightblock (white).
Fig. 10.
4. Setting up/testing.
The PIR 360º sensor is provided with two test mode
functions. One is the LUX test and the other is the
PIR test.
a)LUX TEST mode, measuring daylight level.
Master only. Set the switches DIP1 and DIP2 to ON.
In this position the light will be off. Slowly turn the
LUX setting from Min. to Max. until the integrated
indicator (LED) switches on. At this point the LUX
setting is identical to the daylight level measured
by the sensor. If the daylight level in the room is
adequate, turn the LUX setting towards minimum
until the LED switches off and leave the LUX
setting at this level.
If the LUX setting is turned towards Min., the light
is switched off at a lower daylight level.
If the LUX setting is turned towards Max., the light
, N is switched off at a higher daylight level.
Finish by setting the switches DIP1 and DIP2 to OFF.
b)PIR TEST mode, PIR go test.
Set the switches DIP1 OFF and DIP2 to ON for all units.
In this position, the light switches on in 5 seconds
as a result of PIR activation, while the integrated
indicator (LED) signals PIR activity.
PS: In this test the daylight blocking will not be
working.
Finish by setting the switches DIP1 and DIP2 to OFF.
c)LED indication ON, signaling PIR activation.
Set the switch DIP1 to ON. You are recommended
to switch it to OFF to indicate monitoring.
d)PIR sensitivity adjustment
Switches DIP3 and DIP4 allow you to adjust the
sensitivity of the sensor. The factory setting is
high sensitivity. In some situations it may be
necessary to change the setting. The options are
described in Fig. 7.
The PIR sensor is preset in the factory:
• The sensor is automatic
• LED is off
• High sensitivity
• As master unit
