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
- PA system / additional loudspeakers
- Filter Board with Speech Adapter FBSAR 1009505000
- Power Distribution Board PDB 1009970100 (This Board is only required in an E26 installation. E7 and E20 has +24VDC outputs.)
One FBSAR can feed two speakers or two PA amplifiers from two subscriber lines.
Installation
- 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 or other source of power. Use a 1-pair ordinary installation cable for this purpose; the cable is not supplied with the board.
- Run the wires according to Figure 1.1.
- 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.
