Praesideo 3.5 Installation and User Instructions ISO7240-16: 2007

7.2.2Where 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

alarm signals.

7.3 Evacuate signal

 

7.3.1The 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.

7.3.2The 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.

7.5Audible warning - Optional function

Praesideo offers the possibility to configure a call macro with an evacuation signal or evacuation message only.

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.

7.5.3The audible warning shall be silenced automatically when the s.s.c.i.e. is reset from the voice alarm condition.

7.6Delay before entering the voice-alarm condition - Optional function

dIt 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.

7.7 Phased evacuation - Optional function

Praesideo silences the audible warning signal upon acknowledge of the voice alarm condition. Acknowledge and reset can be combined in a single action.

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.
