SHIP DEVICE FOR FIRE DETECTION Russian patent published in 2018 - IPC G08B17/00 

FIELD: fire safety.

SUBSTANCE: invention relates to the pre-fire and fire situations on ships monitoring means. Device contains N monitoring devices 1, connected to the fire detectors 2 groups by the communication lines, control and annunciation panel 3, external annunciation activation device 4, annunciation backup devices 5, microprocessor 6 connected to the monitoring device 1, which outputs are controlled by the microprocessor 6 through the channels switch 7, are connected to the analog-to-digital converter 8 and to the microprocessor 6, to which annunciation backup devices 5 are connected to the control and annunciation panel 3 through the external ports, RS485 serial interface external port, external annunciation activation device 4, memory device (MD) 10 real time clock 9 is connected to the microprocessor 6 data bus. Monitoring device 1 includes in-series connected short-circuit protection unit 11 and the voltage modulator 12, current sensor 13 and the voltage adder 14, by the inputs connected to the current sensor 13 and to the short-circuit protection unit 11, the voltage modulator 12 and the current sensor 13 outputs are connected to the LAN through the microprocessor 6 controlled key devices 15.

EFFECT: technical result consists in the detection time reduction and increase in the fire detection reliability.
