Connecting microphones and speakers
The audio channels will work with most line-level audio equipment. Use microphones with
a pre-amplifier that delivers audio at line-level (3 V peak to peak). The module can transmit
audio to speakers that accept line-level signals. Please read any instructions that come with
your microphone regarding the adjustment of sensitivity. The module can be used with the
following Honeywell audio devices:
TP800/TP2-800GY
Speaker and microphone unit
IS215TCE-MIC
PIR detector with built-in microphone
DT7450-MIC
