Abstract

PROBLEM TO BE SOLVED: To easily reset a smoke sensor after its operation during a test by providing an automatic switching part which switches the reset switch of the smoke sensor provided to a monitor device to its reset side after the test operation of the smoke sensor. SOLUTION: After checking the operation of the smoke sensor, an operator operates a switching instruction transmission part and sends a switching instruction signal so as to reset the smoke sensor. The switching instruction signal from the switching instruction transmission part is received by the receiver 23 of the automatic switching part 16 and supplied to an auto micro 21 through a connection line 22. Then the auto micro 21 operates to move a rod 20 in a specific direction, and consequently a grip part 19 moves to switch the lever 18 of the reset switch 15 that the grip part 19 is gripping to the reset side, thereby resetting the smoke sensor.
