The present invention relates to an apparatus for testing an audible pedestrian signal device for crosswalks. A breaker is installed to block between infrared transmitter and receiver of the audible pedestrian signal device installed inside a chamber, and an operator to start the breaker are installed on an outer side of the chamber. A tester can block infrared rays transmitted and received from/by the infrared transmitted and receiver of the audible pedestrian signal device by operating the breaker installed inside the chamber, with the actuator outside the chamber. Thus, the apparatus enables the tester to simply carry out a test without needing to block the infrared rays in person inside the chamber, and without needing to block between the infrared transmitter and receiver in person, thereby making the test simple and significantly improving efficiency of the test. |
