Clause / Requirement
The emergency detection system shall also
be capable of receiving information
regarding faults in the sound system and
shall include a provision, usually at its
control and indicating equipment, for
appropriate audible and visual indication of
such faults. As a minimum, the sound
system shall be capable of transmitting to
the emergency detection system one
general "Sound system fault" for any of the
fault conditions listed in 5.3 that may occur
within the sound system.
The link between a fire detection and alarm
system and the voice alarm system is of
crucial importance in maintaining the
integrity of overall operation. It may be
desirable on larger systems, where
distributed control equipment is used, to
provide a link at each control equipment
location rather than to rely on a central
location. Each link shall be monitored. The
voice alarm system shall be capable of
continuing to broadcast alarm messages,
which have been initiated by the fire
detection and alarm system, even in the
event of a subsequent fault in the
interconnecting link between the two
systems (i.e. the voice alarm system shall
"latch" on receipt of a signal from the fire
detection and alarm system). Interruption
by higher priority broadcasts shall still be
possible.
In complex buildings in which actions, such
as initiation of evacuation signals, silencing
of alarm signals, etc., can be implemented
at remote voice alarm equipment,
consideration shall be given to whether
there is a need for such actions to be
indicated at any central fire detection and
alarm control and indicating equipment.
