ZSD100, AUTOMOTIVE AND HOUSEHOLD SECURITY SIREN DRIVER

The audio signal of the ZSD100 is generated using a squarewave oscillator whose output is capable of directly driving a wide range of output circuits.

To produce a characteristic alarm siren sound, the frequency of the audio oscillator is swept over a fixed 2:1 range by a second, low frequency oscil
