This circuit, you can create a siren has two characteristics, the automatic is a siren. Sirens and custom. The circuit uses CMOS nand gate digital IC number IC 4093 features Quad 2-Input NAND Schmitt Trigger makes it easy to use and very diverse. This circuit can be used with speakers or amplifiers to additional offline..........
