Abstract
PURPOSE: To improve safety and to unload a plurality of locks with one operation equipment by composing an electric lock system that consists of an acoustic/electric conversion circuit, a code judgment part, an electric lock drive part, and a tone generator and does not expose an operation part. CONSTITUTION: When a mode-setting switch 2d is set to absence and input is made by a tone generator 1, input is made to an interphone master machine 2 via a door phone slave machine 3 that is an acoustic/electric conversion circuit, a code judgment part discriminates a password, and drives an electric lock control device 4 when the password matches and unlocks an electric lock 6. On the other hand, when the switch 2d is set to presence and there is a call from a door 5, a handset 21 is picked up for responding, and an unlocking switch 2e is operated for unlocking. An electric locking unit incorporating the acoustic-electric conversion circuit, the code judgment part, and a drive part may be installed in the door 5 and the sound output of the tone generator 1 may be inputted immediately after that for unlocking.
