Gallagher Integration

Audio Annunciation from Command Centre

When a Gallagher output fires, the right clip plays on the right speaker - without a dedicated audio server, paging console, or scheduler.

Gallagher · Axis ACAP/Shipping
Overview

The Audio Bridge is an ACAP that turns Axis network audio devices (C8110 and family) into Gallagher-aware annunciators. It subscribes to Command Centre outputs, alarms, or schedules and triggers per-event audio clips via the device's native mediaclip API. Configuration lives on the device - there is no separate audio middleware to install or maintain.

Capabilities

What it does, said plainly.

01

Per-event clip mapping

Map any Gallagher event source (output, alarm, schedule) to a specific clip, with priority and pre-emption rules.

02

Native mediaclip playback

Uses the device's built-in mediaclip.cgi - supports the same clip library you already use for paging.

03

Completion ack

Optional acknowledgement back to Gallagher when a clip finishes - useful for evacuation and drill workflows.

04

Per-device API key

Each device authenticates against Command Centre with its own scoped key. No shared secrets.
