Below are answers to some of the more common questions we are asked from our customers.

  • Re-using old stations - Unless you have the M&S MC602 model you WILL have to replace ALL room intercom stations and patio intercom stations. If you are replacing a Nutone system of any type you will also have to replace doorbell stations, ceiling speakers and controls.
  • Wiring can always be re-used as long as these wires are home run straight back from each station to the master intercom. This is typically how most old M&S and Nutone systems were wired.
  • Drywall work - Drywall or patch work is not necessary since upgrade systems are designed with adapter plate options. BEC Audio also makes Custom Sized Frames for unique applications.
  • Master unit housing - The rough in box or housing that is in the wall for the existing master unit does have to be replaced when upgrading using the M&S or Nutone intercom upgrade products. If you decide to upgrade using the IntraSonic RETRO-M Intercom you will be able to re-use the rough in housing in the wall as long as it is no taller than 10 inches in height. 
  • IPod's, Blue-Tooth, and CD players - We have a few different options for you here. The IntraSonic RETRO-M Intercom Offers a portable music device compartment for iPods and iPhones with USB port for charging. There is also a Bluetooth device option with this system. This system does not have a CD player option. M&S Systems DMC1 & DMC3-4 offers the option to add a single disc CD player / iPod combo unit. This option also has a USB for charge. The M&S Systems also have an option for a six disc CD player (white only). The Nutone Intercom System NM100 & NM200 do not offer iPod iPhone capabilities and the CD player by Nutone has been discontinued. If keeping costs down is what you have in mind but you would still like to play your portable music through the system, we do offer master units with 3.5 mm Jack.
  • Choosing the right Stations - If you have the model number of your existing master unit most of our questions would be answered. If you have an M&S system now, the model number is typically on the bottom right-hand corner of the master units. It is hidden on the bottom of the master unit so you will need to look underneath. You can do this without removing the master unit. If you have a CD player it is likely that this unit would be blocking the model number. If you are replacing a Nutone, the model number is often on the front of the master unit and sometimes behind a closed door on the master. If you have no luck finding the model number you can remove one of the interior room intercom stations and simply count how many individual wires are connected to it. Typically you will see 3, 4 or 6 wires connected.
  • Door Stations - if you are replacing an M&S Systems Intercom with M&S Systems you can always reuse the door station. If you are replacing a Nutone Intercom System you will need to replace this regardless of which product you upgrade with.
  • Ceiling and Wall Speakers - if you have existing M&S music only ceiling or wall speakers you can reconnect these in some cases (if replacing system with M&S Systems) but not all. If you have Nutone music only ceiling or wall speakers you will not be able to read connect these two ANY new upgrade system. The IntraSonic RETRO-M Intercom Is the only upgrade option that allow ceiling and wall speakers to be connected directly to any room station or patio station. The IntraSonic RETRO-M Intercom does use 8 ohm speakers so you will not be able to reuse your existing M&S Systems speakers or your Nutone Intercom System speakers. However, if wiring is run from the ceiling or wall speakers directly to the room station or patio station you will be able to reuse the wire to install new speakers. You will need to check the size and of the current speakers.
