Description:

This kit is designed to make speaker as siren. It is supplied by 9V dc through terminal block, J1. Within the supply 9V to the kit, it still can be controlled by switch either on or off. Transistors are necessary to be installed to the kit as amplifying the output performance. Without the transistors, the volume from the speaker will be very low. Transistors are used for amplifying 9V dc. NPN transistors are installed in this kit. NPN transistor is one of the two types of bipolar transistors. When there is a small current entering the base , it is amplified to produce a large collector and emitter current. Speaker of the kit is controlled by transistor too. Hence, transistor will become active if there is a positive potential difference measured from the base of Q6 transistor to its emitter.
