What is Inspected in an Elevator Emergency Call System?
A modern elevator emergency call system must do much more than simply trigger an acoustic signal in the shaft. For elevator installations covered by Annex 1 No. 4.1 of the German Industrial Safety Regulation (BetrSichV), an effective two-way communication system in the car is mandatory. This system must allow an emergency service to be reached at all times.
The Technical Rules for Operational Safety (TRBS 3121) specify these requirements: The system must enable voice communication in both directions. An entrapped person must not only be able to send an alert but also communicate actively with the emergency service. During an elevator emergency call functional test, the focus is therefore on the following aspects:
The currently applicable standard is DIN EN 81-28:2022-08, which covers remote alarms for passenger and goods passenger lifts. Although a draft for a revised version (DIN EN 81-28:2025-09) was published in 2025, the 2022 edition remains the authoritative standard until its final replacement.
- Can the emergency call be triggered properly from inside the cabin?
- Is the connection to the designated emergency service established without errors?
- Is clear two-way voice communication possible in both directions?
- Can the emergency service immediately identify which elevator the call is coming from?
- Does the emergency call system work during a power outage of the elevator installation (backup power)?
- Are existing faults or error messages detected automatically?
- Are all labels, instructions, and pictograms in the cabin clearly legible and present?
