Clause / Requirement Compliance Signature
d any short-circuit or interruption in the
transmission path between the VACIE
and fire alarm devices when used (see
7.8).
The Plena Voice Alarm System
does not offer this functionality
directly: control inputs are
supervised, but control outputs are
voltage free relay contacts. It is the
responsibility of the installer to
create a feedback signal
(corresponding to the transmission
path status between the Plena
Voice Alarm System and the fire
alarm device) to a supervised input
contact of the Plena Voice Alarm
System.
e failure of any power amplifier. All Plena Voice Alarm System
power amplifiers are supervised for
overload, overheating, short-
circuit, ground short and amplifier
defect.
8.2.6 Indication of faults related to the
transmission path to the CIE (option with
requirements)
The VACIE may have provision for an
indication of faults related to the
transmission path to the CIE. In this case,
the short-circuit or interruption of the
transmission path to the CIE shall be
indicated by means of a separate light
emitting indicator and/or an
alphanumeric display. Plena Voice Alarm System is
compliant.
All input contacts of the Plena
Voice Alarm System can be
supervised for short and
interruption.
Open Interface connections are
supervised through keep-alive
messaging.
Faults related to the transmission
path to the CIE are therefore
individually reported and can be
inspected using the front panel of
the controller or the logging
application. The faults are also
reported through the general fault
warning indication.

alarm zones (option with requirements)
