I have existing wiring for my doorbell that goes from the front door to a closet. No actual doorbell or chime is hooked up, just wiring. When I connect a 24v transformer to the closet end, I'm detecting very low to non existent voltage at the front door.
Just a note, the existing wire is a, i think, cat 3 wire. It has 6 total wires, pair solid and stripped blue, green and orange wires which i believe are 24 awg. The construction contract probably went cheap and saved a few pennies with these wires since the distance is no more than 50 feet.
I did do some googling and tried a few things listed below with no luck. Any help recommendations is appreciated.
- Installed 24 Volt transformer (multimeter detected ~28), connected 1 wire each to the 2 screws on the transformer, doorbell detected ~0 volts
- Installed 24 Volt transformer (multimeter detected ~28), connected 3 wires (twisted together) each to the 2 screws on the transformer, doorbell detected ~2 volts
- Tested continuity. Twisted 2 wires together where the doorbell is and tested near the transformer with no luck. Multimeter got no beeping noise.
- Tested resistance with the same setup as above. I get 0.5 M ohms.
- Tested with a wire tracer/tracker to make sure the wire is correct. I do get noise from both ends. Not sure why this is working with the super high resistance, but it is working...
FYI: I'm using Wire Tracker Tacklife CT01 and Klein Tools Auto Ranging MM400.
I'm stumped on this. Not sure what else to do besides calling an electrician and having him re-wire with a proper bell wire (20awg) which i'm guessing is the main issue.
