The HFI-SIM-01 Intelligent Sounder Interface module is designed for use with the Hyfire range of modular wall sounders and sounder beacons. When either the conventional sounder or sounder beacon are fitted with this module they can then be installed directly onto any Hyfire compatible intelligent loop. Once installed on to an Hyfire compatible loop the device is fully addressable and benefits from an extensive range of intelligent control and monitoring functionality.
