<p>PROBLEM TO BE SOLVED: To provide the sensor abnormality decision device of the terminal device which shorten hs the operation time of an inspector and greatly improves the operation efficiency without disturbing the monitoring operation of a monitor center, and accurately and easily decide operation abnormality and miswiring of a sensor. SOLUTION: To inspect operation abnormality or misconnection of sensors 40 to 43, the mode is switched to an inspection mode by operating a switch 38 of the terminal device 3 and then its switching information is transmitted to a CPU 31; and detection signals of the sensors 40 to 43 are diagnosed to decide whether or not the building facilities are abnormal, decision information is displayed at the display part of the terminal device 3, and the decision information is stopped from being sent to the monitor center 1. The inspector forcibly turns ON the sensors 40 to 43 and then can confirm the display at the display part, thereby easily deciding the operation abnormality or misconnection of the sensors 40 to 43 without disturbing the monitoring operation of the monitor center 1.</p> |
