How To Clean the Controls on a NuTone N485 Apartment Intercom Speaker 

Hi Drealenry: Make sure you don't disconnect more than the "Ring" Wire - otherwise you may disable station in other units in your building - Chris

Hi Wayne:Thanks! - Chris

Hi Crabsoft: If you have a 2 Entry Door System - You must have either a Model 466 - 2nd Door Control Module or a Model 467 Timer Module installed in the 478. The circuity that controls the Door Release is more complex than "just a resistor" but a resistor is used to change voltages within the circuit when the Door Release Switch is activated - Chris

Hi Claude: Any electrical voltage in the wires is low-voltage, less than 16 volts - so it won't harm you. Make sure that the bare ends of the wires do not touch each other when they are disconnected form the apartment station - Chris

Hi Ian: The N485 Apartment Stations are unique to the the NuTone 478 Apartment Intercom system and there are no other choices for Remote Stations - Chris

Hi Jeffery: Here's a link to our Video that show how to clean the Controls on your original 485 Apartment Stations: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_B7d-Z7MZXQ.html Chris

Hi axeonvonshadow: There is no provision to turn off the Call Tone - unit by unit - for the 478 System using N485 Remote Stations. I can think of a way to do this, however - since your units Station is part of a larger System (the entire building) nothing should be done that will effect the units - Are you a renter or do you own the unit? - Chris

Hi Hughie: Is your stainless steel station part of an Apartment Intercom System? - Chris

yes it is a six button unit but sprayed when raining heavily.

Hi cinefil500: The NuTone N485 Aprtament Stations (which are for the 478 System) were made between about 1982 through 2005, or so - Chris

@@northsideservicecompany3567 Thank you for your information, maybe that intercom is rather old. From Spain my country there're intercoms rather different, maybe they're more similar a telephone and in this link you have a intercom old with this style [ cloud10.todocoleccion.online/vintage/tc/2014/11/02/16/46004050.jpg ] even older than this intercom of your video, this intercom is about the 70s and it's a Golmar intercom, but in Spain there're intercoms similar to the american intercoms too, like this Fermax Fonoporta intercom [ upload.wikimedia.org/wikipedia/commons/8/84/Fonoporta_fermax.png ] even older than this intercom of this video about the 70s too.
