orientation light adjustable

• 

Sensor and power supply in one housing

• 

Infrared remote control

2. Operation

The presence detector controls the light automatically according 

to people present (movements) and the ambient brightness.
The integrated light sensor constantly measures the ambient light  

and compares it with the brightness level on the detector. If the 

ambient light is sufficient, lighting will not be switched.  

If the ambient light level is below the brightness level, a move-

ment activates the lighting in the room.
The detector switches the light off, if there is enough natural light 

for 5 min. or if no movement is detected for one follow-up time.
The second channel can be interpreted as HVAC channel 

(heating, ventilation, air conditioning). This channel switches the 

connected load independent of the brightness. 

 3. Safety advice

!

   

Work on the 110-240V mains supply may only be 

carried out by qualified professionals or by instructed 

persons under the direction and supervision of quali-

fied skilled electrical personnel in accordance with 

electrotechnical regulations

!

  Disconnect supply before installing!

!

  This device is not suitable for disconnection.

!

   After having connected all cables, please mount the 

cap onto the detector.

4.  Mounting FC

A circular opening of diameter 68 mm must be drilled into the ceil-

ing. Having connected the cables in accor dance with regulations, 

the detector is inserted into the opening as shown in the drawing 

above and has to be fixed into position by means of the spring clips.

!

   In Master/Slave operation, the master device must always 

be installed at location with least daylight.

6. Self test cycle/Startup behavior

The product enters an initial 60-second self-test cycle, when the  

supply is first connected. During this time, the device does not 

respond to movement and stays on. 

The initialization mode can be changed by using the remote 

control.

7. Putting into operation / Settings

Twilight-switch for constant light control

The set value brightness can be adjusted at between 10 and 

2000 Lux. Using the potentiometer, the set value brightness 

can be adjusted as desired.

:  Day/night time operation

Follow-up time for light control

The time can be set infinitely variably  between  

1 and 30 minutes.
Symbol 

TEST

: Test mode  

Every movement switches on the light independent of 

brightness for a period of 1 second, switching it off for a 

period of 2  seconds.

Orientation light

The follow-up time can be set infinitely variably at between 

5 and 60 minutes. Manually switching ON/OFF the 

orientation light.  

„ON“ for permanent orientation light 

„OFF“ for deactiviation of orientation light

Follow-up time for device control

The follow-up time can be adjusted between 5 min. and

120 min. The delay is active from a set time of >15 minutes.

This delay is about 5 min. If no other movements are detec-

ted during this time, the delay starts again.

Impulse function

The impulse function can be used to control external HVAC 

systems. All 9 s will be set a 2.5 sec.

Alarm impulse

In order to initiate an alarm impulse, there have to be three 

detected movements within a period of 9 sec.

This function can be used to display a presence in the room 

on external visualizations. All 9 sec. will be set an impulse 

of 2.5 sec.

The device does not fulfil the requirements of DIN EN50131-

2-2 and therefore cannot be used in professional intrusion 

detection systems.

Pulse spacing PD-Slave

2 or 9 seconds can be set for the pause between 2 pulses 

sent to the master. The setting can be made with activated  

( ) or deactivated ( ) LED indicator.
For devices with a separate slave input, 2 sec.  

can be set.

9. Manual switching and dimming

By pressing the push button, the phase can be given to the S

terminal.
To turn on or off, press the push button briefly. The light will remain 

on or off, as people are detected plus the follow-up time.
With a long key press the light will be dimmed manually. When

you release the button, the current brightness value is retained.

Upon renewed dimming, the dimming direction is reversed.
Taking the phase to the R terminal by using a button, the HVAC 

channel can be switched with a short key press.
