20p no sound from siren

May 24, 2017 2 Replies

Hello All,



I removed xfinity I control from my panel. The alarm sound only comes from my keypads. I have already confirmed the sounder works. I have even added aux PS but no sound.



I'm thinking it's in the programming somewhere. Any thoughts?


20p only puts out voltage not siren tone if sounder is only a speaker then you need a siren driver to make whoop sound

Shouldn't be anything in programming might be a bad board

power supply isn't usually needed unless you have a lot of other powered devices, you could always tell when Vista panels needed a PS when they blipped the siren and the keypads momentarily lost power
