A siren is one of the important alarm devices that notifies others about an unauthorized intrusion into an object. By the principle of signal formation, they can be divided into 2 groups: piezoelectric and electromagnetic. Piezoelectric models, which include the S-77 1-Tone 20W, are in demand due to their low power consumption for their maintenance and the possibility of using them in low-voltage networks. They can have an internal power supply or be designed to operate from a standard network with a specific voltage value.
The miniature model S-77 1-Tone 20W is designed for use in a 12V power supply. It can be installed in a regular car or minibus.
