INTRODUCTION

The ZSD100 is a frequency swept alarm signal generator designed specifically for static and automotive security alarm systems. One ZSD100, two timing capacitors, an in-expensive TO92 darlington, piezo transducer and coupling transformer is all that is necessary to produce an ear piercing 120 dB alarm siren.
