FIRE EXTINGUISHING APPLIANCE FOR ENGINE ROOM

PURPOSE: To repair the trouble of an electric valve driving means and an electric valve in advance by displaying the fact that the occurrence of a fault in electric valve driving means and electric valve sides is detected based on the detection of a valve opening/closing detecting means. CONSTITUTION: When a defective condition in the connection of an electrically operated valve 22 and a connector 152 occurs due to an unknown cause, or the contact of a limit switch 147 is located at the intermediate position between an HC terminal and an NO terminal, a transistor 112 is turned on, which inverts output to 'H'. Therefore, the output of an exclusive NOR gate 132 is inverted to'H' by the inversion of its input, which turns on a transistor 133. In such a way, a start-up/fault display lamp 33 puts on successively. Also, when the fault occurs in a motor driving IC element 128, the output of the exclusive NOR gate 132 is inverted to 'H' similarly, which turns on the transistor 133, and the start-up/fault lamp 33 puts on successively.
