Bosch Security Systems B.V. IUI-PRAESIDEO_4.0 | V1.0 | 2013.01 Installation and User Instructions
7.3 Audible warning (option with requirements)
An audible warning of the voice alarm condition might be
the same as that for the fault warning condition. If they
are different, the voice alarm condition warning shall
have priority.
Output contacts of the Praesideo system can be
configured in the site specific data as either Emergency
alarm buzzer or Fault alarm buzzer. A buzzer must
always be connected to the output contact to generate
the actual audible warning. A single buzzer can be used
as audible warning device for both the voice alarm
condition and the fault warning condition, by using a
parallel connection of the output contacts of the
Emergency alarm buzzer and the Fault alarm buzzer to
control the actual buzzer.
The Praesideo system does not offer priority handling for
the Emergency alarm buzzer (i.e. the Fault alarm buzzer
is not automatically silenced when the Emergency alarm
buzzer is activated).
7.4 Delays to entering the voice alarm condition
(option with requirements)
The VACIE may be provided with a facility to introduce a
delay before entering the voice alarm condition. In this
case:
Since the Praesideo system does not process the fire
sensors, this functionality is better handled by the device
managing the fire sensors (the CIE). The Praesideo
system itself does not implement this requirement.
a the operation of the delay shall be selectable at
access level 3;
b the operation of the delay shall be in increments not
exceeding 1 min up to a maximum of 10 min;
c the delay to one output signal shall not affect the
delay to other outputs;
d it shall be possible to override the delay by a manual
operation at access level 1;
e there shall be provision to switch on and switch off
delays by means of a manual operation at access
level 2 (see Annex A for information on access
levels);
f there may be provision to automatically switch on
and/or switch off delays by means of a
programmable timer which shall be configurable at
access level 3;
g a separate discrete light emitting indicator and/or a
field on the alphanumeric display shall be visible
when a fire signal is received and the delay activated.
This indication shall be suppressed when the VACIE
enters the voice alarm condition.
7.5 Phased evacuation (option with requirements) Praesideo is compliant.
The VACIE may have a provision to phase the warning
signals to the emergency loudspeaker zones. The facility
shall be configurable at access level 3. There may be
provision to switch on and switch off the phased
evacuation sequence by means of a manual operation at
access level 2 (see Annex A for information on access
levels).
Phased evacuation can be accomplished by phased
triggering of input contacts that start the same voice
alarm call in different zones. The device managing the
fire sensors (CIE) is responsible for the phased triggering
of the contacts. Voice alarm calls can also be started via
the Open Interface, where the device managing the fire
sensors (CIE) is responsible for the phased invocation of
the necessary Open Interface methods.
The input contacts must be configured at access level 3.
Using the Open Interface requires access level 2.
Praesideo also offers the possibility to start up to 5 calls
simultaneously from a single input contact or key,
configured as ‘Call activation key’ or ‘Start’, where
phasing can be implemented using accurately defined
periods of silence in the call macros, preceding the
actual tone or message. The installer shall configure the
calls correctly using these chimes/messages (at access
level 3) and use call station keypad keys to switch on
and off the chimes/messages (at access level 2).
7.6 Silencing of the voice alarm condition Praesideo is compliant.
7.6.1 Silencing of the voice alarm condition from the
CIE
7.6.1.1 Where the voice alarm condition has been
triggered from the CIE, the VACIE shall respond
appropriately to a silence instruction from the CIE.
Voice alarm calls triggered from the CIE can also be
stopped from the CIE. To reset the voice alarm condition
an Acknowledge Emergency and Reset Emergency
action is required.
