PeytonM Posted November 24, 2018 Report Share Posted November 24, 2018 I had some work completed on my Electronics International tach and now I’ve got a blown circuit breaker labeled “PHONE.” (See pic below) I’m going to have the panel reopened and find out what happened. In the meantime, any ideas what this CB is protecting? I thought maybe it was the spare microphone, but that works. (I used to have a King KMA24 audio panel, but replaced it several years ago with a PMA450.) Quote Link to comment Share on other sites More sharing options...
carusoam Posted November 24, 2018 Report Share Posted November 24, 2018 Easier on the eyes? open and look down from the top to see if anything has fallen down on top of it...? great use for an inspection camera... Best regards, -a- Quote Link to comment Share on other sites More sharing options...
PeytonM Posted November 24, 2018 Author Report Share Posted November 24, 2018 Thanks. How’d you do that?? Quote Link to comment Share on other sites More sharing options...
carusoam Posted November 25, 2018 Report Share Posted November 25, 2018 Peyton, Until the forum software stops accidently rotating our pics.... Save, edit, rotate, done, exit... then click to choose file... Done! No special apps, or skill required... just an ordinary iDevice.... The I device software isn’t perfect either, as some buttons may disappear or relocate when you push the rotate button...

(I used to have a King KMA24 audio panel, but replaced it several years ago with a PMA450.) The KMA24 used two breakers. The one labeled "AUDIO" and the one labeled "PHONE". It has been a while but I believe the "PHONE" breaker powered the headphone amplifier and the "AUDIO" powered the rest of the panel. When your PMA450 was installed the installer probably used the "AUDIO" breaker for PMA450 power and left the "PHONE" breaker unused. My guess it isn't powering anything and may be shorting to the frame. Jim 1 Quote Link to comment Share on other sites More sharing options...
