What voltage is a intercom system?
While every intercom product line is different, most analogue intercom systems have much in common. Voice signals of about a volt or two are carried atop a direct current power rail of 12, 30 or 48 volts which uses a pair of conductors.
What should I replace my NuTone intercom system with?
For older systems, the only available replacement parts are door speakers. If you need other replacement parts, it will be necessary to replace the entire system. Generally the existing wire can be used. We recommend the Intrasonic RETRO system .
How many wires does a NuTone door and patio station use?
The NM200 uses either 6 wires or Cat5e. While the NM100 master station can work with both 3 and 4 wire systems, there is one room, door and patio station built specifically for a 3-wire system and a different room, door and patio station built specifically for a 4-wire system. Keep this in mind when ordering.
