This document (prEN 81-28:2020) has been prepared by Technical Committee CEN/TC 10 “Lifts, escalators

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.

— A new Annex ZA has been developed in order to be aligned with the requirements of the EU Commission

The content of this document provides the design rules, examinations and tests for alarm systems for lifts.

This document is intended to be used in conjunction with the parts of the EN 81 series of standards calling for

the use of this standard, which give 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

The lifts concerned and the extent to which hazards, hazardous situations or hazardous events are covered

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

This document covers the risk of entrapment of users in the car and in the well, and gives the technical

requirements for the alarm systems for passenger and goods passenger lifts, as described in the EN 81 series.

— site testing to verify the requirements of this document have been met before the lift is used.

— the failure of the communication network (see Annex A), including mobile network signal strength or

— the failure of the network power supply such that all the lifts in a geographical area create entrapment

This document is not applicable to alarm systems for lifts installed before the date of its publication.

Between the acknowledgement and the end of alarm, any alarm filtering shall be bypassed.

After acknowledgement, if the communication is interrupted, the alarm equipment shall stop automatic re-

Any alarm shall not be impeded or lost even in cases of electrical power supply switching or power supply

Where an emergency electrical power supply is used, means shall be provided to automatically inform the

rescue service and to indicate at the installation of the failure of the emergency electrical power supply. This

is considered to occur whenever the emergency electrical power supply is incapable of holding sufficient

capacity to provide one hour of function of the alarm system including 15 minutes voice communication.

If the transmitter is integrated in the alarm system (e.g. GSM-module), the requirements of the standard
