European foreword
This document (prEN 81-28:2025) has been prepared by Technical Committee CEN/TC 10 “Lifts,
escalators and moving walks”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 81-28:2022.
EN 81-28:2025 includes the following significant technical changes with respect to EN 81-28:2022:
— editorial corrections to assist in understanding;
— replaced term “alarm” status to “alert” status;
— replaced term “alarm system” and “alarm equipment” to “two-way communication system”;
— clarification and streamlining of requirements;
— changes in verification of the safety requirements and/or protective measures;
— the Annex ZA has been updated.
This document is intended to be used in conjunction with EN ISO 8100-1:— , which gives the basic
requirements for passenger and goods passenger lifts.
This document is part of the EN 81 series of standards. The structure of the EN 81 series is described in
CEN/TR 81-10:2008.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
Under preparation. Stage at the time of publication: prEN ISO 8100-1:2024.
Introduction
This document is a type-C standard as stated in EN ISO 12100:2010.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate in the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
When requirements of this type C standard are different from those which are stated in type A or type B
standards, the requirements of this type C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type C
standard.

4 Safety requirements and/or protective/risk reduction measures
4.1 Introduction
Two-way communication systems shall comply with the safety requirements and/or protective measures
of Clause 4.
In addition, two-way communication systems shall be designed according to the principles
of EN ISO 12100:2010 for relevant but not significant hazards which are not dealt with by this document.
4.2 Two-way communication system
4.2.1 Initiation device
At least one initiation device shall be provided in the car.
At least one initiation device in the car shall be located at a height between 850 mm and 1 200 mm from
the car floor.
Initiation device(s) shall be yellow in colour and identified by one of the following symbols:
IEC 60417:2025-5013
(ISO 4190-5:2006, Table C.1, No 1)
ISO 7000:2019-2301
(ISO 4190-5:2006, Table C.1, No 1)
4.2.2 Alert activation
The alert shall be activated after the operation of an initiation device and filtering. It is permitted not to
activate the alert if the initiation device is operated for less than 3s.
4.2.3 Filtering
Filtering shall only be applied to initiation device(s) in the car.
Where filtering is applied, it shall occur only when:
a) the car is running; or
b) the car is in an unlocking zone; and
1) the car and landing doors are fully open; or
2) in the case of hinged landing doors, the car doors are fully open and landing doors are unlocked.
It shall be possible to disable filtering.
No filtering shall occur between the lift identification acknowledgement and the end of alert.
No filtering shall occur when the initiation device is continuously operated for an adjustable time
not exceeding 30 s.
4.2.4 Initiation of communication
Two-way communication system shall initiate communication to the reception equipment when the alert
is activated.
The two-way communication system shall emit the lift identification to the reception equipment.
Initiation of communication shall be considered successful when the two-way communication system
receives the lift identification acknowledgement from the reception equipment.
If communication is not successfully initiated within five minutes at the latest, the two-way
communication system shall initiate communication to an alternative reception equipment.
4.2.5 Two-way voice communication
After successful initiation of communication, two-way voice communication shall be established between
inside the car and the reception equipment.
If the two-way voice communication is suspended before the end of alert, operation of the initiation
device or request from reception equipment shall re-initiate the two-way voice communication.
4.2.6 End of alert
The two-way communication system shall be capable of ending the alert by an intentional reset on site
and upon a request from the reception equipment.
