From: dave on 5 May 2008 13:14 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 |
