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.

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.
8.6 Fault-warning condition output signal
The s.s.c.i.e. shall have an output to transmit the fault-warning
condition specified in 8.2. The output signal shall be given if the
s.s.c.i.e. is de-energized.
The Praesideo network controller provides two predefined
control outputs for audible and visual fault indicators with fail-
safe behavior. When de-energized, the contacts of these
control outputs are closed (activated).

9 Disabled condition - Optional function
9.3 Indication of specific disablements
9.3.1
Each emergency loudspeaker zone shall be indicated by
means of separate light-emitting indicators and/or an
alphanumeric display. The indications shall not be suppressed
during the voice-alarm condition.
The optional disablement condition is not supported by the
Praesideo system.
