Abstract

PROBLEM TO BE SOLVED: To provide an electric lock tester capable of quickly finishing a test on an electric lock without removing it from a door and eliminating a personal error in a test result because of experience and of individual maintenance workers for always performing appropriate diagnosis. SOLUTION: In the first place, ordinary wiring connection to terminals T1-T7 in the electric lock 1 is removed, and then, terminals S1-S7 of a main body case body 10 are connected to the terminals T1-T7 via lead wires respectively. Under this condition, when a test switch 18 is pressed, a magnet coil 2 of the electric lock 1 is magnetized. The magnet coil 2 is demagnetized when pressing operation to the test switch 18 is released. This magnetization/demagnetization is informed to the main body case body 10 via a two-way switch 4, and opening/ closing of the door is informed to the main body case body 10 via a reed switch 3. According to this information, pilot lamps 19, 20, 21 are turned on/off.
