Door Buzzer/Intercom

The door buzzer/intercom system to my building stopped working. The model number is 2000 by Jeron, installed in 1987. In anticipation of this day, I e-mailed Jeron a few years back for a schematic and while they were responsive to my query, they had no schematic available for this model. They've moved on to things like retinal and fingerprint scanning.

It's a basic system. The person outside hits the button for the appropriate apartment and an annoying warble rings inside. You hit the "Talk" button to communicate with the outside and then hit the "Listen" button to hear their response. If you decide to let them in you hit the "Door" button to buzz them in.

Does anyone have a schematc for this model or a website that goes over a typical circuit? The last time we needed a fix, the transformer went and we needed to get one custom wound so a schematic would be particularly helpful. The whole thing is dead (intercom and door buzzer) so the first place I'll look will be the power supply, including the transformer.

Any and all help is appreciated.

Thanks, Dave

OK. I popped the cover off the control panel outside to have a look. At some point the control module was replaced with a Lee Dan PK-543. Well it looks like they still make them if this is the problem. The only other possible problem could be the transformer which kicks the voltage down to 16 VAC to run the module.

Now here's a dumb question. Where would this transformer be located? It's not behind the control panel outside. I looked around the basement by the circuit breakers/cable/phone lines and couldn't find it there either. Any suggestions where to look?

Thanks.

Doorbell transformers are often located in the attic.

Greetings..

Regarding: "| Doorbell transformers are often located in the attic."

True! Also, all too often all but forgotten about as they create RFI havoc for nearby radio amateurs / SWL etc.! Trying to get the neighbor or business to be cooperative to replace this crude RF transmitter can, and often IS, quite a challenge!

Usually brought to you by the sheer ignorance of a fellow home or business owner that "didn't know" such things could ever happen..

Cheers, Mr. Mentor

Is that legal?

Mine is on the wall in the garage, I've also seen them in closets, never seen one in the attic.

Every one I've ever encountered in the last 40 years around Colorado have been mounted on a rafter in the attic.

But, I'm also sure that the hodge-podge of electrical codes across the U.S.A. could dictate that it be mounted almost ANYWHERE.

Three houses I have owned in Baton Rouge, Louisiana all had the doorbell transformer in the unfinished attic.
