Apartment Intercom Station Service
Common Apartment Intercom Station Problems We Repair
A malfunctioning apartment intercom station can show up in several ways. In some buildings, the station does not ring at all when someone presses the lobby call button. In others, the tenant can hear the visitor but the visitor cannot hear the tenant. Sometimes the door release button fails, the station / handset produces static, the sound is too weak to understand, or the unit works only occasionally. These problems can be caused by worn station components, loose wiring, aging low-voltage parts, power issues, damaged buttons, or a wiring issue .
We regularly service
apartment intercom station issues such as:
dead apartment
intercom stations, weak or distorted audio, no talk/no listen
communication, failed door release, stations that do not ring and
old / outdated intercom stations that are no longer dependable for
daily use.
