いた。[Prior art] A security system has come into use that uses a pair of digital transmission lines to sequentially and cyclically call up crime prevention detectors, etc. by address polling, etc., and collects information from each detector. In such a system, a digital signal is superimposed on the power supply line to each detector, and therefore the current consumption in each detector is naturally limited.

As the number of lines increased, problems arose, such as the inability to maintain a predetermined line-to-line voltage.

In the security device used, each of the security detectors is provided with an operation indicator light and a pulse generator with a large duty ratio, and when the security detector is activated, the indicator lights are lit in pulses by the output of the pulse generator. This solves the above problems.

Furthermore, the operating status is sent from the central monitoring panel 1 to the security company's disaster prevention center via telephone lines, etc., and if it is installed in a building, a signal from a remote switch for the last person to leave is input. It is configured.

1. A constant voltage circuit 22, a transmission control circuit 23, a pulse generator circuit 24, a sensor 25, and an operation indicator light 5 are provided, and when the sensor 25 generates a signal such as a window opening/closing signal or a signal indicating an intrusion of a human body, A digital signal coded to that effect is sent from the transmission control circuit 23 to the central monitoring board 1 via the transmission lines l ₁ and l ₂ . The signal from the sensor 25 is also input as a drive signal to the pulse generator 24, and a pulse output with a large duty ratio as shown in FIG. 3 is applied to the operation indicator lamp 5 to turn it on. The average value of such pulsed current is extremely low,
Even when a plurality of detectors 2, 3, and 4 operate, the drop in line voltage is negligible and is extremely small.

In addition, the operation indicator light 5 is controlled by the central processing unit of the central monitoring board 1 so that it is turned on only during the operation test of the sensor by the operation of the central monitoring board 1.
If the settings can be made using the CPU, the location of the detectors 2, 3, and 4 will not be needlessly known to an intruder or the like.
