• Fast intermittent sounding of the internal buzzer.
• Activating non-disabled alarm outputs (after a delay expiry, if programmed).
• Activating the Global Fire contacts.
• Activating the Fire Link output (if fitted and not disabled).

The 3100 responds by.
• Illuminating the ‘General Fire’ indicator.
• Illuminating the ‘MCP Fire’ indicator.
• Flashing the relevant zone fire indicator.
