The alarm equipment shall ensure that subject to 4.1.6 alarm filtering, the full alarm information (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.
Where the characteristics of the communication network require (see EN 81-20:2014, 0.4.2 e) and 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.
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.
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, iluminated when an alarm has been validated as a true alarm, i.e. after the end of filtering, until the end of alarm;
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;
a green graphical symbol in accordance with ISO 4190-5:2006, Table C.1, No 8., iluminated during voice communication.
In order to allow manual testing of the alarm system, the filter shall be bypassed when alarm initiation device is continuously pressed for an adjustable time not longer than 30 s. However, no alarms initiated during maintenance and/or repair shall be discarded.AS 1735.19 pdf free download.
