2-Way Audio (2–44+ Only)
The system can support up to three TP800 speaker-mic devices via the audio header. To allow connection via
the Audio Header, an Audio Terminal Board must be fitted (part no. A233—2-way Audio Terminal Board).
Alternatively, a 14-way socket can connect directly on to the Audio Header on the main PCB.
The Galaxy 2 Series Audio Terminal Board is a connector that allows 2-way audio communication (speak and
listen) between the panel PCB and the Alarm Receiving Centre. The Audio Terminal Board is connected to a
TP800 speaker mic which allows audio communication via the on-board PSTN/Modem or the plug-on GSM
module. The Audio Terminal Board is fitted to the main PCB at the location shown in the diagram below.

The TP800 modules can be adjusted for audio levels. Refer to the instructions supplied with the modules for
further information.
The wires between the TP800 units must be no longer than 30 metres in total. The wires are connected to the
terminal board as shown in the following table:
