報器。 Inside the small and portable case, there is a key switch that turns the power on and off by inserting and removing the master key, a buzzer that generates an alarm sound by closing the alarm circuit, and a battery for power supply. The circuit consists of a thyristor to prevent the alarm from ceasing to sound unless the master key is turned off when the alarm sounds, a capacitor to raise and maintain a constant voltage at the buzzer terminal, and a resistor and transistor to operate the thyristor. and operate by opening a circuit between the base and emitter of the transistor, and connecting the key switch, buzzer, thyristor, and battery in series,
A crime prevention alarm characterized in that a resistor/transistor is connected in parallel between the thyristor, anode, and gate, and a capacitor is also connected in parallel to the buzzer.
