NOTICE

Nonapplicable for Canadian installations
Usage not conform with the National Building Code of Canada
● Note that for Canadian installations, playing Background music in a fire alarm
or voice communication system is prohibited, per Section 3.2.4.18 of the
National Building Code of Canada.
The inputs of the FHA2054 audio transformer kit cannot be cascaded together as
this will degrade the low-level audio input by introducing excessive load on the
circuit. If a low-level audio signal needs to be transmitted, one output of the booster
amplifier mainboard can be used to send the audio signal to other booster amplifier
mainboards through the high-level input as shown in the figure below.
