The Tone Generator is used to interface to the larger 120W, 250W and 500W amplifiers or other third
party amplifiers where applicable.

Note: The operation and functionality of the 120W, 250W and 500W complies with AS4428:16,
however these amplifier variants have not been third party approved.
The Tone Generator board provides the same features found on the 25W and 50W amplifiers such as:
4 digital inputs,
3 relay outputs (1A),
Remote paging interface,
a strobe output,
100VAC audio output,
LED indications,
Volume Controls,
Messages and
Tones.
All programming, configuring and settings are as per the amplifier board.

Note: The Tone Generator’s 100V Speaker line output can only accommodate 250W of speaker load.
Therefore, when using the 500W amplifier an Audio Line Splitter must be used to be able to utilise and
distribute the full 500W.
