Niko DALI-2 BMS 41-742 User Manual

Presence and motion detector DALI-2 BMS
41-742, 41-743 and 41-745
Valid for software version 2 -

Use

DALI-2 BMS detector 360° is used to detect presence and to measure the
actual light level. The detector is connected directly to a DALI bus.
The detector can be installed in connection with a BMS / CTS system.
This gives an effective and energy-saving solution that is integrated with the
application controller.
The detector is DALI-2 compliant and complies with the relevant DALI
Standards. The detector has its own address range on the DALI bus,
which means that the number of detectors does not affect the number of
luminaires that can be connected to the DALI bus.

Function

The detector is connected to the DALI bus. To achieve complete coverage
when using several detectors, is an overlap of approximately 30 %
recommended. Fig. 2.
The detector does not contain a full daylight control. It can only provide
information about presence and lux level. The underlying application
controller must be able to handle daylight control.

Installation

Location:
The detector responds to movement and heat in the surroundings. Avoid
positioning the detector close to heat sources such as cookers, electric
radiators or ventilation systems or moving objects such as hanging mobiles,
etc. This may result in unintended activation.

Installation height 2-3,4 m
Installation height 4-8 m
Installation height - type 41-742 and 41-743:
The recommended installation height for this detector is 2–3.4 m. 2.5 m is
the ideal installation height. At this height, the detector has a range of Ø20 m
on ground level and Ø13.5 m at 80 cm table height (without lens cover).
Fig. 6.
Installation - type 41-745:
The recommended installation height for this detector is 4–8 m. At this
height, the detector has a range of Ø16–32 m on ground level (without lens
cover). Fig. 7.

Connection:

The detector must be connected to the DALI bus. Once connected, the
detector will be ready to operate after approx. 2 minutes (warm-up time).
Connect the detector according to the connection diagram.

Setting

Factory setting:
Sensitivity: High sensitivity, all segments
Lux Range: 0 - 1023 lux
All settings of sensitivity and lux are made via the application controller.
In addition, an IR remote control type 41-934 (accessory) can be used for
testing, settings of sensitivity and for software version control.
In order to use the IR remote, the detector must be provided via the DALI
bus.
In order to change settings, the detector must be unlocked. The detector
is automatically locked after five minutes if this is not done manually. Any
changes to settings will be saved. When settings have been programmed,
the green LED turns off briefly, acknowledging that information has been
received correctly. Fig. 9.
Lock/unlock:
Press "Lock / unlock" once to unlock the detector for setting. The green LED
lights up when the detector is in the setting mode.
Press "Lock / unlock" again to lock the detector - operating mode. The green
LED turns off.
