Clause / Requirement Compliance Signature
NOTE - See Annex E for additional
information relating to the interface
between the VACIE and the CIE.
If input contacts are used for
connection of the CIE to the Plena
Voice Alarm System then the input
contacts can be monitored for short
circuit and open line. If the Open
Interface is used for connection of
the CIE to the VACIE, the
communication is monitored using
keep-alive messaging.
7.1.2 The mandatory indications and or
outputs shall not be falsified by multiple
alarm signals received simultaneously
from the CIE and/or manual controls.
The Plena Voice Alarm System offers
one alarm priority.
7.1.3 Where the VACIE and CIE are in
separate cabinets, failure of the
transmission path between the CIE and
the VACIE shall not result in any loss of
control or any change of state of the
VACIE.
The Plena Voice Alarm System is an
autonomous subsystem that can
operate without connection to the
CIE. The effect of the failure of the
transmission path between the CIE
and the Plena Voice Alarm System is
limited to fault reporting and losing
interaction between the CIE and the
Plena Voice Alarm System.
The system must be configured
correctly for this.
7.2 Indication of the voice alarm
condition
Plena Voice Alarm System is
compliant.
7.2.1 The presence of a voice alarm
condition shall be indicated on the
VACIE, without prior manual
intervention, by:
a a visible indication by means of a
separate discrete light emitting
indicator (the General Voice Alarm
Activated indicator);
A voice alarm condition is indicated
on the Plena Voice Alarm System by:
– A red indicator on all call
stations (the system status
LED).
– A textual indicator on the
controller display.
– A red indicator on the
controller.
b a visible indication for each
activated voice alarm zone where
manual controls are provided (see
10.2);
The controller and routers have a
separate LED per zone to indicate
activation of all zones.
