use 

The indicating unit 3-8 has up to eight boards. Each of these boards 
has three input channels.  

Each channel has two terminals. When connected, a signal circuit is 
closed between the terminals. If a VLX .. A-Ex is connected, only the 
first channel can be used. All other channels have to be closed 
(bridge).  

If the signal circuit of the first channel is closed, the indicating unit is 
in good state. If the signal circuit is interrupted, the alarm is triggered 
at the LAE. 

Note:

  

Unused channels in the indicating unit must be bridged. 

In the event of an alarm, the internal buzzer sounds on the indicating 
unit and indicator lights on the keypad light up.
