The MHS 811 Repeater Panel is a simple upgrade element of the analog addressable Electric Fire Detection and Alarm System LITES, that indicates situations of connected C.I.E.`s
MHU 110 and MHU 111, and enables their control.
The Repeater Panel can work in two basic modes - in an activ or a passiv one. In the activ mode the Repeater Panel as a control panel permits, beside the signalling of the C.I.E`s situation, also its full control. In the passive mode the Repeater Panel as a signalling panel displays only the situation of the C.I.E. without the possibility of its control. However on occasion it is possible to take the controlling competences also from the passiv panel, and switch it over into the activ mode (the current activ panel switches over to the passive mode). It is possible to connect at most 3 panels and 4 C.I.E.`s to a system.
The Repeator Panel complies with the standards ČSN 34 2710, ČSN 73 0875 and ČSN EN 54-2.
