The KR-I interface branching box is an expansion module, by means of which the number of control panels in the LDS system is increased and new outputs of system fault signals (Alarm outputs) are added.
The device provides:
- connection of up to six ROM control panels;
- continuous monitoring of communication with the connected ROM control panels;
- indication of the status of the connected control panels;
- receiving audio signals from one of the six zone control panels and transmitting them to the central control centre
control panels and their transmission to the central module CMU-200;
- continuous monitoring of communication with the CMU-200 module;
- generation of four fault signals in the system on command from the central module CMU-200;
- control of main and backup power supply voltages, automatic transfer to backup power supply in case of main power failure and vice versa.
