Elevator, alarm and gate: the devices to check first
The devices that often depend on a copper line, and why to check them first.
- Elevator phone: the cab's emergency line is usually a code requirement.
- Fire alarm panel: the communicator to the monitoring center may carry inspection requirements.
- Gates & entry phones: many call boxes dial out over a landline.
- Fax & card terminal: medical, legal and retail offices sometimes keep these as backups.
- Your main business number: if it's on copper, plan the port so you keep it.
- Common replacements include cellular line-replacement devices, internet calling, fiber, or cellular failover. The right one depends on the device and the building.
