IEC60849 - 5.5 Interface with emergency detection system
table 10: IEC60849 - Interface with emergency detection system
Requirement
The communication link between the
emergency detection system and the sound
system shall be continuously monitored for
faults. This is normally performed by the control
equipment for the emergency detection
system, which gives an audible and visual
indication of a fault in the link between the two
systems.
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.
