User manual
Motion detector 8 m high ceiling,
master, 41-771
The detector is delivered with a lens cover - can be
adapted or removed for correct coverage.

Operation

Motion detector 360° 1-channel master, consists of an integral
unit, featuring On/Off control of 1 channel, motion detector, light
sensor and integrated IR receiver.
Pushbutton power switch and light fittings are connected directly
to the detector which is mounted directly on the ceiling. The
detector can be installed and operated using the factory settings.
However, for optimal light regulation, it is recommended
that you adjust the detector settings to the conditions of the
premises (light requirements). This is done via the integrated
potentiometers or IR remote control type 41-926 (accessory).

Installation

Location:
The detector responds to movement and heat in relation to the
surroundings. Avoid placing the detector close to heat sources
such as ventilation systems, or moving objects. This may
cause unwanted activation. If installed in warehouses where
closed trucks are used, reduced functionality may occur due to
differences in temperature being so slight. Fig. 1.
Range:
The recommended installation height for this detector is 4-8 m.
At this height the detector has a range of Ø 16-32 m on ground
level (without the lens cover). Fig. 2.
Extending the coverage area:
It is possible to increase the coverage area by using motion
detector 41-773 (slave). It is possible to connect 10 slaves
(41-773) to one 41-771 (master) which will control the load
with its settings.
Master and slave motion detectors have the same range.
To achieve complete coverage by using several detectors,
it is recommended that an overlap of approximately 30% is
calculated. Fig. 3.
Installation:
The detector is designed for mounting on the ceiling. Fig. 4.
Connection:
The detector must only be connected to a power supply once

all wire connections have been connected. After connection
to the power supply, the detector will be ready to operate after
approximately 40 seconds (warm-up time).
The red LED flashes during warm-up. The end of the warm-up
time is indicated with two short flashes from the green LED.

Glossary
App. = Application, the method by which the detector will
function.
Active on = The detector only switches on the light if the push-
button power switch is activated, depending on the lux setting.
The light switches off automatically after a predetermined time
after the last registered activity.
Auto on/off = The detector switches the light on automatically
depending on the lux setting when activity is registered in the
coverage area. The light switches off automatically after a
predetermined time after the last registered activity.
Short press on = Press the pushbutton power switch < 1 second.
This may switch on the light, depending on the setting.
Long press = Press the pushbutton power switch > 1 second
and is light-independent.
ECO off = Short press < 1 second, switches off the light at the
same time. The detector will be blocked for 10 seconds.
Settings
Factory settings: Fig. 6.
App.: Auto On/Off with the option for short press On and ECO
Off.
Short press is light-dependent.
Lux: 200 lux
Time (Off-delay): 10 minutes
Sensitivity: High sensitivity
Settings:
Settings can be changed via potentiometers under the cladding
or by using the IR remote control type 41-926 (accessory).
Selection of applications:
The detector can be set to function as: Active On/Auto Off or
Auto On/Auto Off. This is done via DIP switch 1. Fig. 6.
It is also possible to select various functions using the connected
operating button(s). This is done via the DIP switch 3. Fig. 6.
Setting of applications:
DIP switch 1:
On: Auto On/Off
Off: Active On/Auto Off
DIP switch 2:
Not used
DIP switch 3:
On: Only short press On. (ECO Off and long press deactivated)
Off: Option for short press On and ECO Off. For long press > 1
second the light will be switched on or off constantly for two
hours + the set cut-off time, switched on or off.
