Fire linkage how to control the strong switch?
The linkage signal line and the first fire linkage 24V power line is connected with the input / output in the fire four terminals on the module (colloquially called the four line), then the two output lines in the other two terminals, the two output line also connected with one end of the relay, relay control a power switch, relay power closed relay power separation.
When the alarm system alarm, the linkage alarm host through a signal line to multi input / output module issued a directive, and 24V power line to start with the current action module, then the module into action, sending current to the relay, power switch for completion. At the same time, the module feedback the signal that has already been operated by itself through the signal line to the fire engine.
Fire fighting linkage system is an important part of automatic fire alarm system. Usually include fire linkage controller, fire control room, display device, transmission equipment, fire electric control device, fire fighting equipment, emergency power supply. Fire fighting electric device, fire fighting linkage module, fire hydrant button, fire emergency broadcast equipment, fire fighting telephone and other components and components.A high voltage switch is a circuit breaker in a power system (including home power)".
