Abstract
A signal detection system for use with a signaling system is disclosed, the signal detection system comprising a plurality of electrical terminals including a source terminal and an output terminal, the output terminal being connected to a signaling device. An auxiliary terminal electrically coupled to at least one of the plurality of electrical terminals is provided. A current sensor is coupled to the auxiliary terminal for detecting an electrical signal for controlling the signaling device. The current sensor generating an output signal in response to the detection of the electrical signal for controlling the signaling device for monitoring the status of the signaling device. Also disclosed is a method for installing a signal detection system in a wayside signaling system including a signaling device for monitoring a status of the signaling device. An apparatus for connecting a current sensor to a signaling device is also disclosed.
