Signature
h An attention-drawing signal shall
precede the first message for 4 s to
10 s. Successive signals and messages
shall then continue until either
changed in accordance with the
evacuation procedure, or manually
silenced. The interval between
successive messages shall not exceed
30 s and attention-drawing signals
shall be broadcast whenever periods
of silence might otherwise exceed 10
s. Where more than one attention-
drawing signal is used, such as those
used for different types of emergency,
each signal shall be clearly
distinguishable in character.
Compliant, if attention-drawing
signal is part of the pre- recorded
message and the configuration has
been setup to include this signal.

Default configuration is compliant.
Various messages are pre installed
as examples.
Where pre-recorded messages are
used they shall be held in a non-

monitored for availability.
Flash memory is monitored with
checksum.
The system design shall make it
inherently impossible for an external
source to corrupt or derange the store
or its contents.

configuration via external PC is
password protected. Other
external connections are not
available.
