Greetings Folks; I'm in the process of trying to figure out why a siren that someone else installed isn't working. I have a analog port running through a relay to a Wheellock Emergency Alert Device. When calling the analog extension it just rings. The relay activates and I'm getting warble out of the Wheellock on my butt set. I'm now stuck. I have no drawings and not sure exactly how this set-up is supposed to work. All you get when you call ICM 335 is ringing when your supposed to hear alarm warble. Is there anyone that has experienced this? Or does someone have a drawing that might lead me in the right direction?

Thanks; Clueless!!
