Compliance
If the configured call of the emergency microphone was
given a higher priority than the calls that generate alert and
evacuate signals within the same emergency loudspeaker
zone, these calls will be aborted and mute.
Praesideo will resume overruled calls after the overruling
call has finished, providing that the overruled call was
without live speech and had emergency priority.
The emergency state that was entered upon starting a call
with emergency priority, will remain until explicitly manually
reset.
Praesideo allows for free assignment of emergency
loudspeaker zones to calls that may contain live speech or
prerecorded messages.
This assignment can be manually during operation or in
advance during configuration.
Praesideo allows more than one microphone to be
configured for calls with the same priority, but in that case
typically the most recently activated one will not be enabled
until the previous one has finished, i.e. first come, first
served. Only in case of the highest priority, 255, multiple
calls with this priority act on overruling basis, i.e. the most
recently activated microphone will be enabled.
Only one microphone will be active at any one time in the
same zone.
Praesideo allows for configuration of zone groups,
containing one or more emergency loudspeaker zones.
Calls can be made to a free selection of zones and zone
groups.
