High output multi-message
Maxi Fire-Cryer Voice
Sounders from Vimpex are
being used to enhance safety for
maintenance staff working on
Sydney Harbour Bridge.Workers
undertaking regular maintenance
tasks can now be safely evacuated in
the event of an emergency through
pre-programmed messages that are
broadcast from the Maxi Fire-Cryers.

In this application, the challenge
was to keep the maintenance staff
informed of any emergency situation
whilE working in a noisy, outdoor
Security Pty in partnership with
Vimpex developed a wireless voice
evacuation solution to meet this
requirement.

Ten Maxi Fire-Cryers, each with
four messages, have been installed in
the maintenance cribs and active repainting
areas, which are relocated
from time to time. The Maxi Fire-
Cryer outputs 116dBA and features a
fully weatherproof enclosure making
it particularly suitable for external
use in large open areas. A specially
designed wireless control panel
connects to Vimpex’s Voice Message
Controller, which in turn controls
the voice message sequencing to
each of the Maxi Fire-Cryers.
