MHS 817
Repeater panel
Repeater panel is a simple upgrade element of the analogue addressable Fire Detection and Fire Alarm System LITES,
Repeater panel is a simple upgrade element of the analogue addressable Fire Detection and Fire Alarm System LITES, that indicates situations of connected C.I.E.`s MHU 116 and MHU 117, and enables their control.
In the system it is possible to connect up to 16 C.I.E.s and repeater panels. All these devices show information about the whole system, unless it is not restricted in the configuration program.
To the repeater panel it is possible to connect a printer, configuration PC, computer of the superstructure, Remote routing equipment and Fire brigade control panel.
