Lift emergency comms after the PSTN

Replacing the line into a lift is the easy part. The verification is the real work, and it is a joint job with the lift maintainer. Confirm the emergency communication equipment is compatible with the new path. Check connectivity actually reaches into the shaft and the car, where radio coverage is often poor. Confirm backup power keeps the emergency phone working through a mains failure, because that is precisely when it is needed. Confirm the automatic test calls a lift is required to make still complete, and that calls are received where they should be.

None of this is connectivity alone. A working data path to the lift motor room does not prove a trapped passenger can speak to someone. The complete lift alarm system, and the standards it must meet, remain the responsibility of the lift maintainer and the building operator.

Lift shafts are hard radio environments, so coverage has to be verified at the car, not assumed from a signal outside the building, and an external antenna is often part of the answer. Keeping the lift line on a reliable, managed path, separate from other building systems, keeps it simple to support.

Netavo provides multi-network IoT connectivity on its own mobile core, which can serve lift communications where a fixed line is being withdrawn. Lift phones can run as lines on Netavo's hosted voice platform over that connectivity. Conformance of the complete lift alarm system with the relevant lift communication standard remains with the lift maintainer, so verify it together.
