- How does a door phone work scientificaly?
A standard doorbell has an electromagnet, which attracts an armature which is attached to interrupter contacts and a clapper which impacts the bell. The electromagnet attracts the armature, causing the bell to be struck but opening the contacts. With the current momentarily shut off, the armature retreats (it's on a spring), closing the contacts so that the cycle will repeat. The usual doorbell requires about six volts to operate, normally supplied by a small transformer.
- Door bell dies out when pushed?
It sounds like the problem is the transformer. The voltage could be too high. You could check the output with a mulitmeter and see if the voltage is within range for the doorbell you are using. If the doorbells keep getting burned out, chances are, there is too much voltage reaching the coil. If you are not using a transformer to get it down to the rated voltage (24v or whatever), that could be the problem.
- How do you connect a four-wire bell cable to the door bell (two switches to one chime)?
All you need is 2 wires, from the transformer, but you need to know the voltage your chimes are. Take the cover off and see the voltage then note the wires and mark them. Wire up the chime with the 2 wires, and wire the transformer with the same 2 wires(YOU may have to tarce the wires if not color coded) wire them to the proper voltage.
