Replace retiring copper elevator telephone lines with voice-capable cellular connectivity that meets ASME A17.1 requirements — with full-duplex voice, DTMF support, E911 location, battery backup, and ongoing monitoring.
Elevator codes (ASME A17.1 and state equivalents) require a two-way communication device in every elevator cab that connects to a monitored location. For decades, this requirement was met with a standard telephone line — a POTS line — because it provided reliable, always-on voice communication with a dedicated phone number.
As carriers retire copper infrastructure, those elevator phone lines are being discontinued. Without a phone line, the elevator is not code-compliant and may not be legally operable. Building owners and property managers need a replacement that provides the same voice communication without depending on copper.
A voice-capable cellular device is installed at or near the elevator. It provides a dial tone to the existing elevator phone, supports full-duplex voice calls, and routes calls to the monitoring service or emergency dispatcher over a cellular network. The elevator phone itself does not change — only the underlying telephone line is replaced.
Both parties can speak and listen simultaneously, just like a normal phone call. This is required for elevator communication.
DTMF tones used by elevator phone systems for auto-dialing and programming are passed through transparently.
Location information is programmed so emergency dispatchers receive the correct building and elevator address.
The device includes battery backup to maintain communication during power outages, as required by elevator codes.
Cellular service with carrier options evaluated for coverage at each elevator location.
We coordinate with licensed elevator contractors when the cab phone itself needs service.
Red Tag Lines managed service provides ongoing monitoring after installation:
