Home intercom, door answering system which wont work

I have just moved into a house which has a basic intercom system built into the wiring of the house. unfortunately it seems to be pretty dead.i have opened up the phone handset inside the house and it all looks pretty well connected. I opened up the outside intercom and it looks fine though there did seem to be two loose (ish) wires hanging free. I also tracked the wiring into the house, and it seems to have its on control box, beside the mains electric box. do you know any basic fixes for this type of system?

    This should be a low voltage system, much like a door bell uses. If the wiring running from the control box to the intercoms looks like speaker wire, it is a low voltage system. Check to see if you have power to the control box. Then using a simple electrical tester, check to see if you have power in the control box, and also at the intercoms. If this appears to be okay, then look for places where the wires may be touching (shorting) inside the connection areas. Also look for frayed or smashed wires. Replace if necessary. If all these things look good, talk to a residential electrician, they install many of these devices, and would be familiar with the interworkings.

    This is a really great question. I've never dealt much with door systems in Chicago, before. I'd love to learn more about them and how they work. Nothing is worse when you get a problem llike this.

No and we have two phones and neither of them can hear the incoming call yet they can hear us. Nothing happened to the phones they were working and then they did not.

Not likely defective, just need to be reset. If I understand correctly, no ring with an incoming phone call, but the intercom feature works fine. The ringer on the handsets is either "off" it will say no ringer or the base station is not communicating correctly. Intercom is handset to handset. Phone calls pass through the base station first. Of course, check the base unit: power on, phone line plugged in, antenna attached. Then try the phone line to check for dial tone with a regular, "old" analog telephone. If you are using these with a PBX, you must have an analog line installed.

connector 5 goes to your gat actuator, 6 is power for the unit, obviously there will be 2 wires for each for a complete circuit.

This unit says it is voice activated. When it is not in use, is it actually off, or is it still using battery power? I am hoping to be able to use this to monitor an invalid in another part of the house....

The units are still drawing power for their receiver sections and voice-activated relay. They will work as a monitor, but your battery life will be considerably less that it would be with a baby monitor or an intercom that's designed for the monitoring function.

All radioes in my home have a loud buzz. started buzzing two days ago. have not plugged in anything different.

I assume this is on AM as FM would typically not do this.

You have a noise generator interfering someplace. I suggest you use a battery operated radio and tune to the buzzing.

Then turn off your main breaker to your house. If the buzzing remains, the problem is external to your house. It MIGHT be a bad insulator on a power pole. See if your electric company will investigate this.

IF the noise totally went away when you killed the power to your house, turn off ALL the breakers then turn on the main and one by one turn the brealers on till the buzzing returns. When it does, analyze what is on that breaker.

Some common in house sources: Bad door bell transformer, ionizer or electrostaic air cleaner, flourescent lights and CFL bulbs, Bad connections in wiring (very dangerous), switching power supplies and "wall wart" adapters to name a few.

Interference in our wireless intercom

Wireless routers operate on 2.4GHz frequency. It's very possible that your intercom is in the same frequency range causing inerference. Try and find the frequency your intercoms operate on. If you can't find it on the unit, search the internet for the name brand and maybe you will find the info. If this is that case, (as I suspect it is), the only alternative I can suggest is to change your intercoms. Be sure to check the frequency of the new intercoms before purchasing. Anything but 2.4GHZ should work fine.
