Kidde Trigger Input & Relay Module, Mains Powered with Battery Backup

The Kidde Trigger Input & Relay Module is a crucial interface device designed to enhance the functionality of your fire and life safety system. Operating on 230V AC mains power with a built-in battery backup, this surface-mounting unit ensures continuous operation even during a mains power failure, providing an essential layer of reliability.

Its primary function is to integrate with interconnected Kidde smoke, heat, and carbon monoxide alarms. When a connected alarm sounds with the temporal three pattern (the standard smoke alarm signal), the module activates its built-in relay. This action can trigger a range of auxiliary devices to provide a coordinated response, such as activating an external sounder, strobe light, or a building management system.

A key application is for use with sprinkler systems. When an interconnected sprinkler flow switch is activated, the module receives the signal and will both sound the interconnected alarms and activate its relay. This dual-response capability is vital for alerting occupants and signalling other systems in the event of a fire.
