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.
Compliant, if properly installed. Responsibility of the
installer.
The following criteria shall be fulfilled:
a When 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).
Compliant.
b Unless damaged as a result of the emergency, the
system shall be available for operation at all times
(or as required by the system specification).
Compliant, if installed with:
• Redundant ring network.
• Spare Power Amplifiers.
• Multiple loudspeaker circuits per zone and one
loudspeaker circuit per amplifier channel.
• Battery back-up / UPS back-up.
• Emergency Call Station in failsafe layout or
Emergency Call Station Kit in the failsafe layout.
Responsibility of the installer.
c The system shall be capable of broadcasting within
10 s after primary or secondary power is applied.
Compliant, if installed with failsafe layout. Responsibility
of the installer.
d Except 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.
Compliant.
e The 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.
Compliant, if attention-drawing signal is part of the pre-
recorded message. Responsibility of the installer.
f At 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).
Compliant, indicated by call stations and/or by a control
output of the Network Controller (if properly installed).
Fault is also displayed by the Network Controller and
the Logging Viewer (optional).
g Failure 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.
Compliant if installed with:
• Spare Power Amplifiers.
• Multiple loudspeaker circuits per zone and one
loudspeaker circuit per amplifier channel.
• Line Supervision set.
Responsibility of the installer.
h An 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.
Compliant, if attention-drawing signal is part of the pre-
recorded message and call macro has been configured
properly. Responsibility of the installer.
