Clause / Requirement Compliance Signature
10 Voice alarm manual control
(option with requirements)
10.1 General requirements Praesideo is compliant.
The VACIE may have provision for manually activating the
voice alarm output condition. If a voice alarm output control
facility is provided the following shall apply:
a a manual control which causes a voice alarm output
condition to be given shall only be accessible at access
level 2;
The Praesideo system can enter the voice alarm output
condition manually via control input contacts, the Open
Interface and call station (keypad) keys, by starting a call
with a high enough priority.
b it shall be possible to activate each voice alarm zone
individually and/or in group(s) of voice alarm zones;
A voice alarm priority call can be manually activated in one
or more individual zones or zone groups. Zone selection is
possible via call station keypad keys or via the Open
Interface (e.g. using a PC Call Station for graphical
representation of zones with mouse or touch screen
selection).
Zones can also be added to and removed from a running
voice evacuation call using the ‘Start’ action, even from
other call stations or control inputs on other system
elements. A separate ‘Stop’ action is available to stop such
a call from any location.
c the manual activation of a voice alarm zone shall not
prevent the mandatory indications and outputs to other
voice alarm zones.
Praesideo uses the concept of audio output assignment to
a dedicated zone. Because different zones use different
amplifiers, the activation of an additional voice alarm zone
will not affect other voice alarm zones.
Praesideo can be configured to abort lower priority calls
and BGM (Background Music) if a voice alarm state is
present.
The mandatory zone related indications are based on the
priority of the active call in the voice alarm zones. This
means that the lower priority boundary of the Zone status
indicator for each zone should be set to include all priorities
of possible alarm calls into that zone. Using priority level
224 as lower boundary is a safe choice, because then the
Zone status indicator will cover all possible alarm priorities
(224-255).
10.2 Indication of the voice alarm zones in an activated
condition
Praesideo is compliant.
The indication for the voice alarm condition in the voice
alarm zone(s) associated with each manual control shall be
available without any manual action and shall not be
suppressed. This indication shall be by means of
a a separate light emitting indicator (the General Voice
Alarm Output activated indicator), and
The voice alarm condition is indicated on the Praesideo
system by:
• A red indicator on all call stations (the system
status LED).
• A textual indicator on the network controller display
• An output contact configured as voice alarm
activated indicator (Emergency alarm indicator).
This output contact can be used to control the
General Voice Alarm Activated indicator.
b a separate light emitting indicator and/or alphanumeric
display for each voice alarm zone and/or an indication
for group(s) of voice alarm zones.
The key-indicators on call station keypad kits (or regular
keypads) can be configured for ‘Zone status’, to show that
a (voice) alarm is active for a specific zone or group of
zones. The indication is based on the priority of the active
call in that zone, see 10.1. c.
NOTE - These indicators may not necessarily indicate
which emergency message is being broadcast in each
voice alarm zone.
10.3 Indication of the voice alarm zones in fault
condition
Praesideo is compliant.
The indication for the fault condition which would prevent
the generation and transmission of the voice alarm signal to
the voice alarm zone(s) associated with each manual
control shall be available without any manual action and
shall not be suppressed. This indication shall be by
