360° presence detector,
2-Ch, 41-330
Operation
The Sensor PIR 360° model 41-330 is a two-channel lighting
control system that is mounted to the ceiling.
The sensor is ideal for use in the following areas:
• Classrooms.
• Lecture rooms.
• Conference rooms.
Function
Classroom function:
The Sensor PIR 360° model 41-330 will initially switch on the
lighting when the manual switch is pressed. After activation, the
channel 2 lighting is switched on. The channel 1 lighting is then
switched on if the light level is lower than the preset value.
If there is no activity in the coverage area and the cut-out delay
of 1-30 minutes has expired, the lighting in channel 2 and then in
channel 1 is switched off, after which the sensor will be blocked.
For switching the light on again, press the manual switch.
The lighting can be switched off manually, e.g. to show a fi lm or
video. The lighting is switched on by pressing the switch again.
If channel 2 is connected in conjunction with blackboard/screen
lighting, will it also be switched on and off manually.
Two-channel lighting:
The use of two-channel lighting provides optimal control and
signifi cant energy saving.
Channel 1: When the sensor is activated, the lighting is switched
on/off automatically, depending on the preset LUX value, in
relation to the measured light level and movement.
Channel 2: The lighting is switched on and off manually. Channel
2 is also switched off when the cut-out delay expires.
Fig. 1A shows how the sensor should be positioned and how
the classifi cation of channel 1 and channel 2 should be set up to
achieve the greatest benefi t from the sensor.

Manual functions:
Manual on:
The lighting can only be switched on by pressings the manual
switch at the door. Channel 1 is switch on if the light level is
lower then the preset value.
Manual off:
When the room is left the lighting can be switched off by
pressings the manual switch at the door. (Channel 1 + 2 will
switch off)
Installation
Coverage area:
The Sensor PIR 360° model 41-330 is designed to be mounted
to the ceiling at a standard height of 2.5 – 3.4 metres, and
should be positioned centrally in relation to the seating in the
room, although the sensor must cover the area in front of the
blackboard/screen, which is where there will typically be the
most frequent activity. Fig. 2.
Limiting the detection range:
If the coverage area is too large, it is a good idea to limit it by
fi tting the enclosed cover. This enables the maximum reach of Ø20
metres to be reduced to Ø12 metres, Ø5 metres or Ø3 metres,
and the angle of 360º can be reduced in increments of 45º.
It is recommended that the Sensor PIR is not installed
where it is exposed to direct sunlight, air fl ows from
air conditioning, radiators, etc. Fig. 3.
Parallel connection:
Mounting of two sensors on the same switch will because of lux-
function affect the control system and is not recommended.
Installation, Fig. 4:
a) The ideal measurement of daylight is obtained by positioning
the Sensor PIR 360º with its light gate facing the source of
daylight.
b) If the Sensor PIR 360º is mounted directly to the ceiling, the
holes placed at intervals of 105 mm can be used. Please
note that the cable entry point is turned 45º in relation to the
fi xing holes.
c) If the Sensor PIR 360º is fi tted to a ceiling box, use the holes
located for this purpose at intervals of 60 mm, and punch
out the base opening.. Guide in the cable correctly and
carefully in accordance with the instructions for a fi xed
installation, and please note that all installation work must
take place with the mains voltage disconnected.
For cable connections, see Fig. 5.
