This is a simple alarm that has a touch trigger that gets acivated everytime it is touched. This circuit is divided into 2 parts- 1). ALARM and 2). TOUCH SENSORS. Alarm part is based on IC UM66 which has a ROM memory of 64 notes and has a built in oscillator and a preamplifier. The touch sensor part comprises transistor BC549 and IC NE555B which makes the touch plate, a trigger.
