Ive recently got a panel for my fire alarm system and I want to be able to use my speaker storbe on my system. I don’t want to use my phone on it because I want the audio device to activate when the panel activates. I have an amplifier the amplifier runs on 12V DC. I need to know how can I get an audio device that will activate when my MS4 activates.
Buy an MP3 board that other enthusiasts have & use like these (I’d recommend the 20-channel one since of course you can have more messages on it than the 4-channel one, though you might need a pretty beefy power source for it just the same):
FN-BC04-TB 4-Button MP3 Player Board – 10W Amplifier, Terminal Blocks,
FN-BC20 20-Channel Stereo MP3 Sound Board with 2x25W Amp & Enclosure
