The Hyfire module range provides an ideal solution to the monitoring and control requirements of most fire detection and alarm systems, ranging from small and simple, to large and complex. By utilising the Hyfire fully digital communication protocol, reliable and fast operation is achieved even when employing the impressive 240 device loop capacity. A choice of mechanical configurations provides easy integration of the units into a variety of field locations. The HFI-IO-SM-01 is contained in a compact housing, which can be easily mounted inside third party equipment and provides the capability to remotely monitor a single circuit and control a single ancillary circuit using external power. Both input and output circuits are monitored for fault conditions. Bi-colour LEDs provide local indication of device status.
