Consequently, the output of the bistable automatically goes low as soon as Si is closed. Under this condition zero base drive is applied to Qi , so that Qi and the relay and the alarm are all off. ... Under this condition pin 2 of the bistable goes close to the positive rail voltage, and the bistable changes mode and its output locks into the high state and switches ...
