In this embodiment, the lighting switch S1 is a dark operation switch consisting of a so-called EE switch, and is attached to the outer wall above the eaves, for example, to avoid the incident light from the entrance light 3, and is installed on the outer wall above the eaves to avoid the entrance light 3 from entering the entrance light 3 in the dark. Turn on.

The human body switch element is attached to the eaves, for example, and includes a sensor that detects a person entering the entrance 2, and switch elements R1, R2, and R3 that are turned on by the output of the sensor. In this example, a non-contact sensor such as an ultrasonic, microwave, or infrared sensor is used as the sensor.

Note that as the human body switch SH, a foot switch or a pressure switch that is attached to the ground surface of an approach or the like, or a limit switch that is attached to a gate or the like can be used.

In this example, the alarm device includes 1 for a first alarm device consisting of a chime installed indoors such as a living room or kitchen, and 2 for a second alarm device consisting of a buzzer installed outdoors, Depending on their respective activations, different alarms are issued: a chime sound and a buzzer sound louder than the chime sound. Writing 1, second alarm 1, and R2 are alternatively selected by changeover switch S2.

The changeover switch S2 is a timer switch in this embodiment, and sets the second alarm to 2 during a set time period, for example from late night to early morning, and sets the first alarm to 1 at other times. Selection operates.

In this example, the changeover switch S2 is a two-circuit, two-contact changeover switch, forming two changeover switches 52AS32B that operate in conjunction with each other.

Further, the contact 1 side is called a greeting state, and the contact 2 side is called an alarm state, and the contact is switched to the contact 2 side during the set time period.

In addition, the entrance light 3, the alarm K, and the switches S1, S2, and SH constitute an electric circuit shown in the second FgJ in this embodiment.

The electric circuit includes a power line L1 to which a power source is connected, a common line C, and a power line L via a main switch SM.
1, and a third line L connected to the second line L2 via the lighting switch S1.
3. The porch light LP and the gate light LM each have one end connected to the common line C, and the other end connected to the third line L3 via the switch elements R1 and R2 of the human body switch SH. Writing device 1, second alarm device 1, and R2 each have one end connected to a common input line C, and the other end connected to a second line L2 via a changeover switch S2A and a switch element R3 of a human body switch SH. ing. Further, a changeover switch 32B and a current control section I are arranged between the other end of the gate light LM and the third line L3.

Further, manual switches S3 and S4 for forced lighting are connected between each other end of the gate light LM and porch light LP and the power supply life L1.

Note that the current limiting section I may include, for example, a phase control circuit using a triac, a thyristor, etc., or an impedance element,
Consists of current control devices such as transformers.

Therefore, even when the main switch SM is in the OFF state, by turning on the manual switches S3 and S4, the porch light L is turned on.
P, the gate light LM can be lit.

Further, in the daytime state, the lighting switch S1 is turned off as shown in FIG. Therefore, even if the main switch SM is turned on, the entrance light 3 remains off. On the other hand, the alarm device is connected to the second line L2, and when the switch element R3 is turned on by the operation of the human body switch SH, the first alarm device K] is activated and issues an alarm consisting of a chime sound, for example. Announce guests.

Also, at night, the lighting switch S1 is turned on as shown in the fourth FgJ, and the gate light LM is lit at 100% illuminance through the conductor wire of one contact of the changeover switch 32B. In this state, when the human body switch SH is activated, the porch light LP is turned on by the switch element R1, and the alarm device 1 of the book collection 1 emits an alarm sound consisting of a chime sound by the switch element R3.

Also, when it is late at night and the set time period has arrived, the changeover switch S2 is automatically switched to the crime prevention state on the contact 2 side, as shown in FIG.

Therefore, the gate light LM is supplied with power through the current limiter (2) and is lit at a low illuminance of, for example, several tens of percent. At this time, the alarm device is switched to the second alarm device. Also, when the human body switch SH detects the intrusion of a person into the entrance area 2, the switch elements R1, R2, and R3 switch the porch light LP from the off state to turn on at 100% illuminance and turn on the porch light LM.
