Requirement

Compliance

Signature

A sound system for emergency purposes shall permit the broadcasting of intelligible information of measures to be taken for the protection of lives within one or more specified areas.

The following criteria shall be fulfilled:

aWhen any alarm is detected, the system shall immediately disable any functions not connected with its emergency role (such as paging, music or general pre-recorded announcements being broadcast to the loudspeaker zones requiring emergency broadcasts).

bUnless damaged as a result of the emergency, the system shall be available for operation at all times (or as required by the system specification).

cThe system shall be capable of broadcasting within 10 s after primary or secondary power is applied.

dExcept during the condition described in 4.1c), the system shall be capable of broadcasting a first attention-drawing signal within 3 s of being placed in an emergency mode by the operator, or automatically on receipt of a signal from a fire or other detection system. In the latter case, the period of 3 s includes the reaction time of the detection system from the time the emergency is first detected, to commanding the alarm broadcast.

eThe system shall be able to broadcast attention- drawing signals and speech messages to one or more areas simultaneously. There shall be at least one appropriate attention-drawing signal alternating with one or more speech messages for this purpose.

fAt any time the system operator shall be able to receive, by means of a monitoring system, indications of the correct functioning or otherwise of the relevant parts of the emergency system (see also 5.2 and 5.3).

gFailure of a single amplifier or loudspeaker circuit shall not result in total loss of coverage in the loudspeaker zone served.

NOTE 1 - The monitoring system specified

in 4.1f) should indicate the failure of an amplifier or of a loudspeaker circuit.

NOTE 2 - Particularly in small buildings, it may not be necessary to install two separate loudspeaker circuits in one loudspeaker zone. A decision on this matter may be subject to local regulations.

hAn attention-drawing signal shall precede the first message for 4 s to 10 s. Successive signals and messages shall then continue until either changed in accordance with the evacuation procedure, or manually silenced. The interval between successive messages shall not exceed 30 s and attention- drawing signals shall be broadcast whenever periods of silence might otherwise exceed 10 s. Where more than one attention-drawing signal is used, such as those used for different types of emergency, each signal shall be clearly distinguishable in character.
