PURPOSE:To economize the method where all systems are controlled in common, by making leads from them to a test panel full-duplex. CONSTITUTION:When a system number is designated by a system designating key 11 of a test panel 1, only a corresponding system is designated on the basis of predetermined information by a corresponding designation confirming part 5, and designation guard information is transmitted to the system, and fault information is transmitted to the test panel 1 to flicker a light emitting diode of the test panel 1. Meanwhile, since designation guard information is cut off in the normal case, the system is in the state of complete connection to the test panel 1. |
