FDU

FDU is used in SB-2 Panel of 3-Phase AC Locomotives. This Fire detection Unit is used to sense any smoke present in the Locomotive during its operation and notify the driver about the same.
FDU indicates the driver about any fault such as rupture, blockage, and leakage in its air suction system Via the LED Indicator display.
The air is captured by suction system which is present in the locomotive. During its normal operation, if smoke is present in the Locomotive, the FDU will sense the smoke and generate the signal and send it to VCU. This message will be transmitted to DDU. DDU will display the fault “Fire Detection” at Subsystem 15, along with title “FIRE IN MACHINE ROOM”
The Fire Detection Unit (FDU), which is installed in a metal case, consists of the following materials:
- Smoke detection unit, 2 smoke detectors are installed inside the case
- Visual indications for operations, fault/malfunction monitoring with alarm
