HELP!!!!

[firehouse]

Hello again Smart People,


I have a Unitrol Touch Master Delta. The other day I was going on a call and it stopped making noise. You can hear it in my vehicle like it is under a pillow coming out of the siren, but nothing out of the speaker. On a previous call, it started acting goofy and cut out occasionally. I had a spare siren and changed it out with a like model thinking it was the siren itself. But it is still making the muffled noise. Siren or speaker?


Thanks,

Sounds like you have just isolated the problem to the speaker or speaker wiring.

if you can only hear the siren "in the box" then its the speaker or wiring. trace all your wiring from siren to speaker if wiring is good to go then your speaker must have pooped the bed.

And whatever you do, do NOT run the siren at ALL when it's not hooked up to a speaker… it's very hard on the transistors and sometimes makes them fry.
