== Description ==
This Filter Board and Speech Adapter with relay provides interface to PA systems.
It has filters that remove the display data carrier from the audio. In this way
excessive heating of power amplifiers is prevented. It also provides DC
termination of subscriber outputs (corresponding to non-display stations).
 
For interface to non-selective mobile radios, it provides two relays that are
controlled by [[RCO]] /c-wire for busy marking of the external equipment and control
of transmitter keying. There are also two optocouplers that can be used for mutual
busy marking.
 
The board has two audio transformers that provide galvanic separation between the
intercom exchange and the external equipment.
 
The relays use +24 V from the exchange. If the relays are not used, no power is
required.
 
The FBSAR is fastened onto the mounting rail on the connection field of the
AlphaCom exchange.
