Plena Voice Alarm System | Installation and User Instructions | IEC60849
table 8: IEC60849 - 5.3 Automatic fault monitoring
Requirement
k Short-circuit or disconnection of visual alarm
devices.
l Failure of a processor to correctly execute its
software program.
m Detection of any error during memory
checking.
n Cessation of any scanning or interrogation
process.
o Failure of the interconnecting data or voice
communication links between parts of a
distributed system.
In addition to individual fault identification at
these locations, a common sounder shall
sound for a minimum of 0,5 s every 5 s. A fault
shall cause the sounder to operate in a latched
mode and a visual indicator to light, either
steadily, or in a flashing mode. Manual
acceptance and reset switching shall be
included. When accepted, the sounder shall
be silenced and the indicator shall change to
(or remain in) steady illumination. The
occurrence of a further fault condition shall
reactivate the sounder and the visual indicator.
When all the faults have been cleared, the
indicator shall be switched off, either
automatically or by operating a reset switch.
The fault indication should be given within
100 s of the occurrence of the fault, regardless
of whether the voice alarm system is being
used for non- emergency purposes, such as
the transmission of background music.
