4 Safety requirements and/or protective measures
4.1 General
4.1.1 Introduction

Alarm systems shall comply with the safety requirements and/or protective measures of Clause 4.

In addition, alarm 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.
4.1.2 Alarm information

The alarm equipment shall ensure that subject to 4.1.6 alarm filtering, the full alarm identification (see 4.1.7)

will be emitted until acknowledgement, even during maintenance.

If an emission fails before acknowledgement, the delay between re-emission(s) shall be reduced to the

minimum compatible with the communication network.

If the communication is interrupted any re-emission after acknowledgement shall not be impeded by the

alarm equipment. The alarm system shall be able to accept communication from the rescue service until the

end of the alarm has occurred.

Emission of the alarm identification to the transmitter shall not be delayed, except during alarm filtering.

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-

emission.
4.1.3 End of alarm

Means shall be provided to enable indication, from the alarm system to the rescue service, that the alarm has

been dealt with and no user is trapped in the lift.

The end of alarm shall be initiated at lift installation from which the alarm call was made. The means to initiate

the end of alarm shall be accessible only to competent persons.

Resetting of the alarm by a signal coming from the rescue centre shall be possible.

4.1.4 Emergency electrical power supply

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

failure.

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

regarding the emergency electrical power supply apply to the transmitter.
4.1.5 Visible and audible signals in the lift car

The alarm system shall be equipped with visible and audible signals, integrated in or above the car operating

panel, consisting of:

a) a yellow graphical symbol in accordance with ISO 4190-5:2006, Table C.1, No 1, illuminated when an

alarm has been validated as a true alarm, i.e. after the end of filtering, until the end of alarm;

---------------------- Page: 9 ----------------------
oSIST prEN 81-28:2020
prEN 81-28:2020 (E)

b) an audible signal with a sound pressure level at 1m from the source between 35 dB(A) and 65 dB(A)

adjustable to suit the site conditions when an alarm has been validated as a true alarm, i.e. after the end

of filtering, until the voice communication is established. The acoustic signal is not required to be

continuous;

c) a green graphical symbol in accordance with ISO 4190-5:2006, Table C.1, No 8., illuminated during voice

communication.
See Figure 1 which clarifies the operation of the visible and audible signals.

4.1.6 Alarm filtering
Provision shall be made to enable the alarm system to filter alarm initiations.

For this purpose, the filter shall be capable of not initiating the alarm when any of the following events occur:

— when the car is in an unlocking zone and the car and landing doors are fully open, or in the case of hinged

landing doors, the car doors are fully open and landing doors are unlocked;
— the car is running.

Where the alarm system is designed to filter inadvertent alarm initiations by setting a minimum time to

operate the alarm initiation device, thi
