Overview
prEN 81-28 (draft 2025) is a CEN type‑C standard that specifies technical requirements for two-way communication systems in passenger and goods passenger lifts. It defines how a lift’s in-car communication must operate to contact a reception (rescue) equipment, including initiation, signaling, automatic testing and emergency power. The standard forms part of the EN 81 series and is intended to be used alongside EN ISO 8100-1. Note: prEN 81-28 is not applicable to lifts installed before its publication and will supersede EN 81-28:2022 when finalized.
Key Topics and Requirements
- Initiation device
- At least one in-car initiation device, located between 850 mm and 1 200 mm above the car floor.
- Initiation device(s) must be yellow and identified with standard symbols (IEC 60417 / ISO 7000).
- Alert activation and filtering
- Alert state is activated after operation of the initiation device and any permitted filtering.
- Short presses (< 3 s) may be exempted from activation; filtering applies only under specific car/door conditions and can be disabled.
- Communication initiation and identification
- Two-way communication must emit the lift identification and receive an acknowledgement from reception equipment.
- If no successful initiation within 5 minutes, communication must try an alternative reception equipment.
- Two-way voice communication
- Full two-way voice must be established after successful initiation; it must be re‑initiable if suspended.
- Emergency supply
- System operation must be unaffected by power failure/restoration/cycling.
- Emergency supply must support 1 hour of two-way communication including 15 minutes of two‑way voice.
- Automatic test
- Automatic connection tests to reception equipment must run at least every 3 days, using the same means as a manual initiation and sending lift identification.
- Failed tests trigger in-car optical indications and reporting to reception equipment.
- In-car signals
- Acoustic signal adjustable between 35–65 dB(A) until voice link is established (measured at car centre, 1.5 m height).
- Yellow symbol illuminated during alert and green symbol during established two‑way voice communication.
- User information
- Instructions must include manual test methods, parameter changes, failure recognition, signal descriptions and alert reset procedures.
Applications and Users
- Intended for lift manufacturers, installers, maintenance/service providers, building owners, and safety/regulatory bodies.
- Applies to design, installation, commissioning and service checks of lift emergency communication systems and rescue procedures.
- Supports compliance with EU machinery and lift legislation via the EN 81 series.
Related Standards
- EN ISO 12100 (risk assessment / machine safety principles)
- EN ISO 8100-1 (basic requirements for passenger and goods passenger lifts)
- ISO 4190-5, ISO 7000, IEC 60417 (control symbols and interfaces)
