New upgraded Appello high output voice signalling sounders

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

The Appello can be configured to replay just the recorded messages or the content can be alternated with one of the 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 the outputs to be fine-tuned to the installed location.

The effective combination of a distinctive warning tone followed by clear spoken instructions ensures that people understand the actions that are required when an emergency alert is generated.
