SIFA is a Dead man’s control system which is designed for all kinds of rail vehicles and consists of the control unit (UDB1 – stanalone or UD19 – evaluation board), the foot switch (UP1 or UP1-D) and the three-tone sound indicator (ZS24, ZS72, ZS110).
The function of the system is to control the alertness of the locomotive driver. In case that the driver, for whatever reason, is not alert, light and sound signals are produced and eventually the braking process is initiated.
The system is designed according to EN50155, EN 50121-3 and EN 61373, as well as UIC 641, IEC 571, IEC 571-1, IEC 571-2.
All system components are made to be durable because of their placement in the locomotive cabin and do not require any regular maintenance.
Central part of the system (Dead Man’s Electronic Control unit UDB1) is connected to the locomotive via 16 pole connector (DIN41622).
System benefits – Dead Man's Electronic Control Unit UDB1/UDB19
Different types of device for different applications – UDB1 is a standalone device which can be implemented virtually anywhere in the cabin while UDB19 serves the same function but it is in a form of evaluation board and can be implemented in standard 19“ inch rack
After fast braking initiated by the dead man’s control unit UDB1/UDB1-19, it is impossible to run the train again without correct service of the push button or of the foot switch. Moreover, to run the train again, an additional button has to be served to reset the dead man’s control unit.
System benefits – Foot Switches type UP1/UP1-D
Durable plastic coating surface protection.
Integrated fold-up switch
Various dimensions available (wide; narrow)
Foot switches can be used in various systems (horn activation, dead man’s control system or sand-brake)
System benefits - Three Tone Sound Indicator ZS24/ZS72/ZS110
Different types for different supply voltages 24 VDC (ZS24), 72 VDC (ZS72), 110 VDC (ZS110)
Loudspeaker with a plastic membrane; water resistant
The device is powered only if one of the frequency inputs is activated which makes the device lifecycle much longer
