MHS 815
Repeater panel
Repeater panel is a simple upgrade element of the analogue addressable Fire Detection and Alarm System LITES, that indicates situations of connected C.I.E. MHU 115 and enables their control.

Documents and certificates
Repeater panel can be set to one of three modes – passive, semi-active and active.
- Passive mode – shows only state of an C.I.E. without possibility of it’s control. Allows cancelling of acoustic signalling. Repeater panel connects to the line SL-RS 485.
- Semi-active mode – allows basic control of C.I.E. (reset, acknowledge of alarm, cancelling of acoustic signalling) and listing of events. Repeater panel connects to the line SL-RS 485.
- Active mode – shows information about the whole system and allows it‘s full control. Repeater panel connects to the line RS 485/422.
