Minute Impulse Shaper FMI-14 for Accurate Subway Time Management

The "minute pulse formulator" FMI-14 (hereinafter, the product or FMI-14) is designed to operate as part of the metro unified time system. FMI-14 is corrected by the external minute pulses from the IFSC or the clock station. FMI-14 is corrected by the setting signal from the reference time device UEV-4m or from the interface unit BI-NTP, which receives information about the exact time from the NTP-server.

FMI-14 is designed for counting minute pulses for secondary electromechanical clocks. FMI-14 is designed to issue corrective signals of the current time for lobby clocks CHV-10(CHV-11). FMI-14 is designed for operation in crossing rooms.

In terms of resistance to the effects of climatic factors during operation FMI-14 corresponds to group K1 according to OST 32.146-2000, but for operation at ambient air temperature from +10 deg. C to +45 deg. C and relative humidity up to 90%.
