Abstract

PURPOSE:To increase the control operability, by enabling switching control of electric lock, through the provision of switching control means for the electric lock of a door for a gate and the like with a button telephone set. CONSTITUTION:A door phone 4 is provided with a sensor detecting the switching state of a door, and when the door is opened, the information is transmitted to a common reception section of a main device 1, and a lamp of burglar proof mark is illuminated on the display of a master set 2 through the corresponding output. To open the door without operating an alarm circuit, an electric lock release button of non-lock type of the master set 2 is kept pressing. Thus, a ground signal is transmitted for the time and unlocking for the electric lock is made. Then, since the lamp of the burglar proof on the display of the master set 2 is illuminated when the door is opened, the restoration to the monitoring state again can be achieved remotely, by keeping depression of the electric lock release button while illumination, and detaching when the lamp extinguishes, after the confirmation that home-comer enters indoor.
