==Calling through PA System==
[[Image:FBSAR PA 1.JPG|thumb|350px|Figure 1.1 Calling through PA System]]

===Feature Description===
The AlphaCom can distribute audio through separate loudspeakers for announcements and music distribution. This audio can be distributed via an FBSAR board. When loudspeakers without amplification are used, there must not be more than 20 such loudspeakers in one system. Such loudspeakers can only be connected via a FBSAR board.

===Equipment List===
* AlphaCom System with desired station range
* PA system / additional loudspeakers
* Filter Board with Speech Adapter FBSAR 1009505000
<br/>
One FBSAR can feed two speakers or two PA amplifiers from two subscriber lines.

===Installation===
====Installing the FBSAR board====
* Fasten the FBSAR board onto one of the mounting rails on the distribution field.
* Supply the board with 24 V and 0 V (GND) from the Power Distribution Board. Use a 1-pair ordinary installation cable for this purpose; the cable is not supplied with the board.
* Run the wires according to Figure 15-4. Audio output connection is done from the Subscriber Connection Board.
* Check the switch settings.

===Additional information===
If you use the FBSAR for the connection no programming in necessary. We do however recommend that you program the physical connection for the PA system as a substation.

==Amplified Calling Through Loudspeaker without Answer Option==
[[Image:FBSAR PA 2.JPG|thumb|350px|Figure 2.1 Amplified Calling Through Loudspeaker without Answer Option]]
===Feature Description===
You use a loudspeaker for voice distribution of incoming calls. You may also choose to have distribution of group calls and audio programs through the loudspeaker. Additional indication of incoming calls may be connected.

===Equipment List===
* AlphaCom System with desired station range
* Additional loudspeakers
* Filter Board with Speech Adapter FBSAR 10099505000
* Power Distribution Board PDB 1009970100
* Power Amplifier WK1000614100
* Mounting box
* Local power supply for the Power Amplifier
* PC with AlphaPro program and cable for connection to the AlphaCom exchange

===Installation===
====Installing the Power Distribution Board====
* See [[PDB - Power Distribution Board]]
If a PDB board is already installed, you need not switch off the entire exchange. Just unplug the connector on the PDB board supplying power from
the exchange.
 '''''CAUTION'''''
 Do not extend power cables from the PDB outside the exchange rack environment. 
 Use local power for remote installation of equipment.

====Installing the FBSAR board====
* Fasten the FBSAR board onto one of the mounting rails on the distribution field.
* Supply the board with 24 V and 0 V (GND) from the Power Distribution Board. Use an 1-pair ordinary installation cable for this purpose. The cable is not supplied with the board.
* Run the wires according to Figure 15-8 Amplified Calling through loudspeaker without answer option. Audio and RCO output connections are done from the Subscriber Connection board.
* Make sure the [[FBSAR_-_PA_interface#Switch_settings|switches]] are in the correct positions.

====Installing the Power Amplifier====
* Mount the board in a mounting box near the amplified loudspeaker
* Install a local power supply
* Connect the cables according to Figure 2.1 Amplified Calling through loudspeaker without answer option


==Station with Amplified Calling and Answer through the Station using Amplifier WK20==

===Feature Description===
The loudspeaker amplifies the calling tones, private ringing tone and canceling tones. When the calling station uses the M-key, the amplifier is switched on and off. When a key on the amplified station is touched or the handset is lifted, the amplifier is switched off.

===Equipment List===
* AlphaCom System with desired station range
* Filter Board with Speech Adapter FBSAR 1009505000
* Power Amplifier WK1000614100
* Power Distribution Board PDB 1009970100
* Additional Loudspeaker
* PC with AlphaPro program and cable for connection to the AlphaCom exchange.
