• How can I determine the model number of a master station?

  Most NuTone intercoms have the model number on the front of the panel. If there is a door that opens on the front, the model will most likely be on a label affixed to the door.

• How can I determine if my current intercom is “looped” or “homerun” wired?

  Older and some current systems were designed to be installed in a “looped” or “home-run” fashion. “Looped” means that the speakers are wired from speaker to speaker to speaker. “Homerun” means that each speaker is ran back to the master, all alone and by itself.

  To determine how your system is wired, a number count of cables at the master and the number of remote speakers must be done. If there are as many cables, as speakers, you have “home-run” wiring. On the other hand, if the number of speakers exceeds the number of cables at the master, your system is “looped”.

• What are the primary cables recommended for NuTone intercoms?

  Listed below are the various models and cable recommendations.
  NM200 –Category 5 (Cat 5)
  NM100 - Will use the existing 3 or 4 conductor cable.

• What is the total number of speakers that can be used on each master?

  The maximum allowable number of speakers varies by model. (See below)
  NM200 – 15 remotes plus 3 doors.
  NM100 – 15 remotes plus 3 doors for 4 wire. 13 remotes plus 3 doors for 3 wire.

• I have an older 3 wire system. Can I update it with a newer system?

  Yes. It can be updated to the NM100 series; however, you will need to change everything except the wire.

• Can I use an MP-3 / I-pod type device with my intercom?

  Yes. In most cases, there is an RCA type audio input “jack” on the back side of the master (inside the wall). Most any auxiliary device of this type (with the appropriate connectors) can be plugged into and played over the intercom system. The IA-30WH wall plate can be used to accomplish this task.

• Can I use Cat 5 cable on the NM100?

  No. This system is designed to be installed on existing 3 or 4 wire cable. Oscillation may occur if Cat 5 is used. (NuTone IWA-3 is recommended for 3 wire updates and NuTone IW-4 is recommended for 4 wire updates.)

• Are the IM/IMA series components compatible with the NM series?

  No. Due to impedance and other electronic differences, there is no compatibility between the two systems.

• Are there “update” frames available for replacing older systems?

  Yes. There are “update” frames for many of the older remote speakers and masters, which in most cases were larger than the current units. Please see our catalog or website for specific frames required.

• Can I use an electronic chime with the NM series intercom?

  No. The stand-alone electronic chimes will only function with the IM/IMA series. They are incompatible with the NM series.

• Can I install the NM series CD player (NC300) with my IM/IMA series master?

  No. Unfortunately, due to voltage and audio reasons, the NM series components are not compatible with the IM/IMA series of intercoms.
