Allowing four different 30 second
long voice,music or sound messages
to be recorded and replayed at CD
quality for improved clarity and
intelligibility, E2S has introduced new
versions of its all-digital Appello
combined voice signalling and tone
sounders.

The Appello can be configured to
replay just the recorded messages or
content can be alternated with one of
45 alarm tones embedded in the unit.

The four alarm stages are remotely
selectable and the message playback
and the alarm tones have independent
volume controls, enabling outputs
to be fine-tuned to the location.

The combination of a distinctive
warning tone followed by clear
spoken instructions ensures people
understand the actions that are
required in an emergency.
