failed doorbells

[bobbymari]

Gotta call this afternoon from an apt owner that all doorbells to units stopped working. First thoughts tripped breaker somewhere. Mind you I haven't even went out yet, just wanted to cheat a little before I did. Most apts I deal with have individual transformers for doorbells to units but are there transformers that will serve multiple units doorbells. Just wanted to pick some brains before I went out, owner says he didn't see any tripped breakers but if I had a dollar for every time I've heard that boyyy i tell ya

One transformer could very well be serving multiple apts. How often would they all be ringing?

If if it a system with a common bell pushbutton panel for all units, they will all use the same transformer and it should be powered from the house panel rather than an individual tenant panel.
If it is only a local bell and pb at each unit, then they might have individual transformers, but could still all wired to a common circuit somewhere, since there will be house power wiring in a variety of places in the building, including hallways, etc.

Can you say, "denial of service attack"? Flashmob goes to apartment building and on cue rings every doorbell in the place simultaneously. Drags the doorbell system to its knees. Gotta call the Doorbell System Adminstrator.
