ISO7240-16: 2007 compliancy checklist
Additional clauses
Clause / Requirement Compliance Signature
EN54-16 and ISO7240-16 are very similar standards.
The following list gives a summary of the differences
between the EN54-16 and the ISO7240-16 standards for
voice alarm control and indicating equipment. Only
essential differences are listed. Differences in phrasing
between the standards (that occur very frequently) are
omitted. Also similar clauses that have a different
number in ISO7240-16 compared to EN54-16 are not
listed. The changes are divided into sections
• Additions: clauses in ISO7240-16 that do not exist
in EN54-16; the ISO7240-16 text is generally given.
• Changes: clauses in EN54-16 and ISO7240-16 that
are basically the same but differ in detail, the change
is given by using italic typeface.
• Exclusions: requirements that are in EN54-16 but
are not in ISO7240-16.
Responsibility of the installer. The installer must use the
checklist for EN54-16 before proceeding with this list for
ISO7240-16
Clause / Requirement Compliance Signature
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.
The optional test condition is not supported by the
Praesideo system.
7 Voice-alarm condition
7.1 Reception and processing of alarm signal
7.1.4 Where 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.
Upon entering the emergency mode Praesideo can be
configured to override non-emergency functions, based
on priority settings.
7.2 Alert signal - Optional function
7.2.1 The s.s.c.i.e. may produce one or more alert
signals complying with ISO 7731.
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).
