Abstract
PURPOSE: To ensure an assured announcement of the fire information by transmitting the detailed information of the fire detector plus the information added to the detector.
CONSTITUTION: The power is usually supplied to detector 5 from the receiver via connection wire 5a and 5b, and no power source 5c for information transmission is supplied. At the same time, transmission line switch circuit 8 within detector 5 is connected to the side of contact output 7. Now, in case detection part 6 of detector 5 detects the physical quantity of the smoke, the temperature and others of more than the prescribed value, the switching circuit of contact output 7 is short-circuited or released. Thus, the information is transmitted to the receiver circuit of the receiver via circuit 8 plus wire 5a and 5b.
