Claims

[Scope of utility model registration request]

In an abnormality detection device configured such that a sensor is provided in series on a track for each section from a monitoring point to a required point, and an alarm is issued at the monitoring point by sensor operation, a fault detector 8 that can be switched to the monitoring point is provided. A series circuit 7 consisting of a diode and a resistor is provided in parallel to the line for each section, and the loop current is measured by the detector 8 which is switched when a sensor or line disconnection is detected, and the measured value is A track fault detection device characterized in that it is configured to detect a point of fault occurrence by comparing and a stored value.
