Installation and Operating Instruction for 

B.E.G.

 - Occupancy detectors PD2-M-2C-24V-3A-SM/-FC and PD2-M-2C-24V-RR-SM/-FC

2a.   Installation of the LUXOMAT

®

 PD2-M-2C-24V-SM

The detector must be installed on a solid 

and level surface. There is no need for 

frames. 

For mounting remove lens (C) (turn 

anticlockwise). Fasten the mounting pod 

to the ceiling.

Having connected up the wires in accord-

ance with regulations, secure the detector 

with 2 screws as per the illustration above. 

In order to assemble the detector outside, the PD2-IP54 base-plate, 

which is available as an accessory, must be mounted between the 

detector and the surface on which it is to be installed.

PD2-M-2C-24V

2b.   Installation of the LUXOMAT

®

 PD2-M-2C-24V-FC

The detector has been designed 

and developed specifically for in-

stallation in suspended ceilings. 

A circular opening of diameter 

68 – 70 mm must be produced in 

the ceiling. 

Having connected up the cables 

in accor dance with regulations, 

the detector is inserted into 

the opening as shown in the 

drawing opposite and fixed into 

position with the assistance of 

the spring clips.

The product enters an initial 60-second 

self-test cycle, when the supply is first 

connected. The occupancy detector is 

ready for operation.

 1. Mounting preparations
 

Work on the 230 V mains supply 

may only be carried out by qualified 

professionals or by instructed persons 

under the direction and supervision 

of qualified skilled electrical person-

nel in accordance with electrotechni-

cal regulations.

 

Disconnect supply before installing! 

 

When in Master/Slave mode of 

operation, the Master-appliance  

must always be installed at the  

location where there is least  

daylight.

4. Settings carried out using remote control (optional)

Remote control LUXOMAT

1. Check Battery:

 

open battery compartment by pressing the 

plastic springs together and removing the 

battery-holder.

2.  IMPORTANT 

Please pay attention, that the setting is Potentio-

meter 1 at “TEST” and Potentiometer 2 

not

 at 

“SUN”. All values which have been programmed 

using the remote control will be deleted in the 

event of power failure in the position “TEST/

SUN”. Please switch Potentiometer 2 over to 

“MOON” or any other value.

Caution:

 

Settings with remote control supersede the 

settings by courtesy of potentiometers.

Resetting when closed

The lighting relay is switched off, i.e.  

opened and the follow-up times reset.

Permanent protection against sabotage

This function blocks the unit permanently (green LED is  

illuminated). This operating mode can only be activated  

during the period of 5 seconds after pressing the “lock“  

button. This status will only permit actuating the function 

“Light on/Light off”.
The procedure for leaving this mode is as follows:

 

1. Switch off the current

 

2. Apply current for 31 – 59 seconds 

 

3. Switch of the current again 

 

4. Apply current 

 

5. Open detector

Light on/off => (see page 2, point 6)

The light will remain switched on/off for as long as move-

ments are detected in the areas of coverage. Once the last 

movement has been detected, the light will remain on for 

the duration of the follow-up time as per setting.  

The appliance will then return independently to the mode 

selected (Fully or Semi-automatic).
