Abstract

PURPOSE:To permit a continous sound to be produced by a method wherein the ticking operation of a counter is started by the signal of commanding alarm sound generation or that from a demonstration switch, and the output of the counter is used to produce an intermittent sound. CONSTITUTION:When a demonstration switch S0 is operated or when a consistent signal C0 is issued because alarming time 5 has arrived, the output of an OR gate 7 reaches the H level and inverts a latch circuit 16, while the flip-flop group F1- F4 starts counting a signal at 32Hz. Synchronizing with the output signal from an AND gate 24 to a NOR gate 23, a signal at 2048Hz is outputted and given to a buzzer 10. Therefore, an intemittent sound consisting of two sounds is generated from the buzzer 10, while the output of the AND gate 22 inverts the latch circuit. When the signal C0 or the signal of operating the switch S0 is kept outputting, the latch circuit is again inverted one second later, so that the intermittent sound is also generated again.
