Additional clauses

Clause / Requirement

6 Quiescent condition

Any kind of system information may be displayed during the quiescent condition. However, no indications shall be given that can be confused with indications used in

•the test condition.

7Voice-alarm condition

7.1 Reception and processing of alarm signal

7.1.4Where the s.s.c.i.e. is used for non-emergency purposes, the voice-alarm condition shall disable or override any functions not connected with the emergency functions.

7.2 Alert signal - Optional function

7.2.1The s.s.c.i.e. may produce one or more alert signals complying with ISO 7731.

Compliance Signature

The optional test condition is not supported by the

Praesideo system.

Upon entering the emergency mode Praesideo can be configured to override non-emergency functions, based on priority settings.

Praesideo offers various alert signals that comply with ISO7731. Also prerecorded signals can be stored and selected in Praesideo.

The installer must select and configure an alert signal that is in compliance with ISO7731 from the list of available signals that Praesideo offers. The preferred signal and required sound pressure level depend on the the actual application, as the parameters of the danger signal (signal level, frequency spectrum, temporal pattern, etc.) shall be designed to stand out from all other sounds in the reception area and shall be distinctly different from any other signals.

The sound pressure level shall be at least 65dBA at any position in the signal reception area, while being at least 15dB above A-weighted ambient noise, but it may not exceed 118dBA.

The danger signal shall include frequency components between 500Hz and 2500Hz. Pulsating danger signals are preferred to signals that are constant in time, while the repetition frequencies shall be in the range from 0.5Hz to 4Hz.

Examples of compliant Praesideo tones are the ‘DIN alarm’ (sweeping signal from 1200Hz down to 500Hz in 1s, repeating) and the ‘2-tone alarm 2’ (alternating frequencies of 650Hz and 850Hz, every frequency lasts 500ms, repeating).
