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!!

You should be able to short out the siren somehow to make it sound to verify that it is working.

Did something change recently? Like a new telephone system? I have ran into when putting new systems that they do not provide enough ring voltage to make the wheelock units work. Just suggestions at this point!

Thanks, for input. No Changes; just quit working.

I'm confused.

Are you saying that the extension rings and you hear ringing from the handset but the Wheelock just doesn't pick up? Where are you supposed to hear the warble from?

Looks to me like the relay just follows the intercom extension's 90v ringing and there is nothing to seize the line so it's not going to pick up. So ringing from the originating phone's handset or speaker is what you are going to hear until you hang up to silence the warble.

Question is how is the output of the Wheelock connected? Apparently the tone generator is working since you hear a warble with your buttset. Normally I would expect the output to be connected to some sort of overhead paging or alert system.

my guess would be a bad siren , I would call wheelock support

have you checked the voltage going to the Siren and compared it what the siren is looking for ?

Yeah, there's a storm on the loose here. Check the relay for closure, if you got that then it's like Skip says or in the wiring

my guess would be a bad siren...

But he has signal on the output.

We need to know more about how this thing is supposed to work before we can say what's wrong. You don't need drawings for that. Surely somebody can tell you how they operate it and what it does. You don't say anything about where the warble tone is supposed to be heard.

My thinking was that he has one of those Wheelock ring voltage to contact closure devices for control, could be wrong and it wouldn't be the first time.

that was my thinking John the relay then to the siren

" I'm getting warble out of the Wheellock on my butt set. "

coming out to the rely but nothing from the siren

so a bad Siren

Yes, that's the response that gets me. What does that really mean? 1. Do I have ringing voltage to the device? 2. Is the relay closing? 3. Does the siren have power? 4. If triggered at the device, does it work?.

Sounds like basic troubleshooting to me.
