发明名称 Signal transmission system for fire alarm junction line
摘要 A novel signal transmission system, having a junction line comprised of a power source line, a grounding line and a signal line is disclosed. Two complementarily operative transistors are connected in series between the power source line and the grounding line. Signals are sent out from the junction point of the two transistors to the signal line. The speed for transmitting the signals is effectively increased due to the quick charge and discharge of the signal line.
