Intercom installation: a guide for pros

What customers ask, how to win the job, and what to put on your profile.

Offering intercom installation

Intercom installation is a low-voltage and door-control job where the customer judges the audio, the video and whether the door opens every time. Win it by planning the cable route, testing every station and being clear about the electrical scope.

What customers ask

  • Can I see and talk to visitors from inside?
  • Will the video work at night?
  • Can I open the door from my phone?
  • How many stations can I add later?
  • What happens if the power goes out?
  • Who fixes it if it fails?

How to win the job

  • On the walkthrough, check the entry, the indoor station spots, the cable path, the power source and the door release type, and write each one down.
  • Show the customer the station layout on paper, with the video field of view at the entry marked.
  • Quote the stations, the cable, the power supply, the door release work and the electrical work as separate lines.
  • Test the call, audio, video and door release from every station before you leave.
  • Set the door release timing and the fail mode with the customer, and write down the settings.
  • Leave a written user guide with the station buttons, the call routing and the warranty contacts.

What to put on your profile

  • Post photos of clean entry stations with the weatherproofing and cable routing visible
  • List the intercom brands and door release types you install
  • State the entry systems you install, including single-building and multi-unit setups
  • Show a sample station layout with the details blurred

Follow-up that helps the customer

  • Offer a camera or video upgrade at the entry once the intercom is working
  • Suggest a weatherproof check of the outdoor station before the wet season
  • Recommend a power backup review when the customer depends on the entry in a power outage

Licenses and permits

Intercom installation often requires a licensed electrician for power supplies, door releases and any new outlet, and some areas require a permit for entry systems. Confirm the requirements with your state or local licensing agency and your local building office before you take the job.

Questions

Can I connect the door release myself?

Door releases are wired to the entry and often to a power supply, so the connection often requires a licensed electrician. Refer that work out, and keep the station and cable work within your scope.

How do I handle a customer who wants the entry to open from their phone?

Explain the setup in writing, including the network, the account security and the power needs. Refer any door release or network connection that needs licensed work to the right trade.

What do I do if the old wiring is not rated for the new system?

Stop before the connection, document the wiring with photos, and recommend a rewire or a licensed electrician. Do not connect a system to wiring that cannot carry it.
