The ZSD100DEMO is an ZSD100 Automotive and household security siren driver evaluation board. The ZSD100 is a frequency swept alarm signal generator designed specifically for static and automotive security alarm systems. One ZSD100, two timing capacitors, an inexpensive TO92 Darlington, piezo transducer and coupling transformer is all that is necessary to produce an ear piercing 120dB alarm siren. Including an audio frequency signal generator, low frequency sweep generator, disable circuitry and output driver stages, the ZSD100 provides every function necessary to produce a standard alarm signal.
