The RETRO Music & Intercom Replacement System is the answer to the age old question of what to do with your existing old intercom system.  This is one of the easiest and cost effective solutions available anywhere!

A Step By Step Approach to Replacing Your Old Intercom:

  • Measure the hole where the old intercom master has been taken out. DO NOT use the old transformers, the Master Station wires directly to 110VAC. **
  • Go go RETRO Master Unit ▸ to find the RETRO Master and Trim-plates with dimensions
  • Usually you can use the old housing and metal clips we include with the RETRO Master
  • Determine if the Old Room Stations are Vertical Stations (V) or Horizontal Stations (H)
  • Go to RETRO  Room Stations ▸
  • Look at front door station, decide on plastic, metal or the RETRO MyDoor Smartphone Doorbell ▸
  • Go to RETRO  Front Door ▸
  • If it is a 2 wire system at the front door get the adaptor *RETRO-DBB (click here, scroll down to read description)
  • A 2 wire front doorbell will only be able to ring through the RETRO system, you will not be able to talk through it
  • Combination packages have a Master, Master Trim Plate, 4-5 Rooms, Standard Front Door, Patio Station and Bluetooth Adapter. You can add Room Stations, AM/FM Antenna, IREMOTE Control, etc. to the package as needed. RETRO Combination Packages ▸
