An apartment intercom has a door station at the entrance that calls each flat, an indoor station in every unit, and a door or gate release. Modern IP systems also let residents answer and open from their phones, add the caretaker's desk, and keep a log of calls.
Key takeaways
- One entrance panel, one indoor station per flat.
- Door release opens the lock or gate from each flat.
- IP systems ring residents' phones too.
- Old 2-wire cabling can often be reused.
- Add a guard or caretaker station.

Many older blocks have intercoms that stopped working. We can replace them with a system that reuses existing cables where possible. See intercom not working and intercom prices.
