What is the principle of a regional fire alarm controller?
The working principle of the controller of regional fire alarm: through the line and the corresponding control module and fire detector, manual alarm button, fire door (fire pump, elevator, fire shutter, smoke fan, exhaust fan......) Linkage device is connected, when connected with the action of these devices (such as detect fire or start etc.), the control module by the device itself or connected with the action, will be converted to electrical signals along the transmission line to the fire alarm, fire alarm through the corresponding electrical signal conversion module will be converted. To display text, image or sound alarm; and vice versa, when the operation of the fire alarm controller through the corresponding button, button function module will convert these into electrical signals through the transmission line to the related equipment, and control the operation by the corresponding module.
The regional fire alarm controller and the centralized fire alarm controller form the automatic fire alarm occasions of large or scattered fire. Regional fire alarm controllers are installed in the protected areas. For example, a room with a regional fire alarm controller, another room also uses a regional fire alarm controller, the two rooms controller can also be centralized alarm controller control.
The regional fire alarm controller has a fire alarm controller that transmits information to other controllers. The regional fire alarm controller is directly connected with the fire detector, dealing with various alarm information, and also connected with the centralized fire alarm to transmit the fire alarm information to it.
