Zusammenfassung:PROBLEM TO BE SOLVED: To provide a fire alarm equipment and a sensor that can execute the sensor test even when the number of connected sensors is unknown in the case of performing a remote test of the sensor and can improve the reliability of the sensor test. SOLUTION: This equipment is constituted by connecting plural sensors 4 through a wire. Then, a sensor test means 8 performs a test one by one from a nearby sensor 4 to an inmost-side sensor 4 by outputting a test signal one by one to plural sensors continuing on the line from the nearby sensor to the inmost-side sensor, and successively receiving a test alarm signal transmitted from the sensor 4 based on the input of this test signal. During this test, a test response means 10 receives one of the test signals outputted to the line and outputs a response signal identifiable as the test alarm signal.
