Bosch Security Systems B.V. IUI-PRAESIDEO_4.0 | V1.0 | 2013.01 Installation and User Instructions
7.2.2 Where a voice signal is used as part of the alert
signal, the alert signal shall precede the first pre-
recorded voice message for 3 s to 10 s. Successive alert
signals and messages shall then continue until either
automatically or manually changed or silenced. The
interval between successive messages shall not exceed
30 s and alert signals shall be broadcast whenever
periods of silence might otherwise exceed 10 s.
Praesideo offers this functionality via its call macros. The
installer must configure the call macros accordingly.
7.2.3 Where more than one alert signal is provided, each
signal shall be clearly distinguishable.
Praesideo offers a wide choice of independent alert and
alarm signals.
7.3 Evacuate signal
7.3.1 The evacuate signal may be preceded by an alert
signal (see 7.2).
The use of an alert signal, together with an evacuate
signal, should be assessed as part of an emergency
management plan (see ISO 7240-19). For buildings and
structures where the plan requires the unassisted
evacuation of occupants, the s.s.e.p. may be configured
to generate a warning signal that does not incorporate an
alert signal.
Praesideo offers the possibility to configure a call macro
with an evacuation signal or evacuation message only.
7.3.2 The evacuate signal shall include the tone signal
and pre-recorded voice messages, as specified in ISO
8201.
Manufacturers may implement other signal templates to
satisfy specific mandated national requirements.
The installer must configure one of the dedicated
ISO8201 compliant evacuate signals that Praesideo
offers. These emergency signals have the temporal
pattern as described by ISO8201 and have a predefined
name
‘Emg x ISO8201 C’, with x being a sequential number.
The installer must ensure that the sound pressure level
of the evacuate signal is at least 65dBA, or 75dBA if the
signal is intended to arouse sleeping occupants.
ISO8201 does not specify pre-recorded voice messages,
but Praesideo offers the possibility to store and select
custom voice messages to satisfy specific mandated
national requirements.
7.5 Audible warning - Optional function
7.5.3 The audible warning shall be silenced
automatically when the s.s.c.i.e. is reset from the voice
alarm condition.
Praesideo silences the audible warning signal upon
acknowledge of the voice alarm condition. Acknowledge
and reset can be combined in a single action.
7.6 Delay before entering the voice-alarm condition -
Optional function
d It shall be possible to override the delay by a manual
operation at access level 1 and/or by a signal from a
manual call point.
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.
7.7 Phased evacuation - Optional function
c When switching from phased evacuation to manual
mode, the phased evacuation sequence shall halt.
Praesideo has multiple priority levels to override (phased
evacuation) calls by manually activated calls.
d When switching from manual mode to phased
evacuation, the phased evacuation sequence shall
resume from the point at which it was halted.
Praesideo will resume manually overruled calls without
live speech but with emergency priority, after the
overruling call has finished.
Clause / Requirement Compliance Signature
8 Fault-warning condition
8.1 Reception and processing of fault signals
8.1.2 The s.s.c.i.e. shall be capable of simultaneously
recognizing all of the faults specified in 8.2, and in 8.3 if
provided, unless this is prevented by
• the presence of voice-alarm signals in the same
emergency loudspeaker zone, and/or
• the disablement of the corresponding emergency
loudspeaker zone or function, and/or
• the testing of a corresponding zone or function.
In Praesideo supervision is always active.
8.2 Indication of faults in specified functions
8.2.2 If the indication is by means of separate light-
emitting indicators, these may be the same as those
used to indicate disablement and/or testing of the
corresponding emergency loudspeaker zones or
functions.
Praesideo uses separate indicators for faults.
The optional disablement and test conditions are not
supported by the Praesideo system.
