Installation and Operation manual
Compliance
The Plena Voice Alarm System provides
an audible fault indication from the
controller and remote control panels.
The optional function 'disablement' is not
implemented in Plena Voice Alarm
System.
Plena Voice Alarm System does not have
an alphanumeric display.
Plena Voice Alarm System is compliant.
The mains and backup power of all Plena
Voice Alarm System elements are
supervised individually, depending on
configuration. The controller and routers
monitor the power sources on a system
level.
All 100V lines of the Praesideo system
are supervised individually for earth
faults (i.e. connections to earth with a
leakage resistance of less than 50 k
Ohm).
Every rupture of a fuse or the operation
of a protected device that affects a
mandatory function will result in a fault
since the mandatory functions are
supervised. The reported fault is as close
to the located defect as possible. E.g. a
mains related fault is reported as a mains
fault and an amplifier defect is reported
as defect for that amplifier.
