referring to fig. 1-8, the plate spring and the return spring are both cylindrical springs. And a reset cover plate is arranged on the reset opening.
When the fire alarm controller works normally, green normally-bright LED light emitted by a light source in the fire alarm controller is emitted through a left optical fiber (such as a POF optical fiber), and then is received by a right optical fiber (such as the POF optical fiber) which is just opposite to the fire alarm controller and then is sent to a photoelectric conversion module in the fire alarm controller for signal processing, the tail end of the warning optical fiber is placed in a warning optical fiber hole, and the flashing light with a certain frequency emitted by other red LED light sources in the fire alarm controller is LED to the warning optical fiber to serve as an indication signal lamp for normal work of the design.
When a fire disaster occurs, the touch panel is pressed down, so that the outer convex hollow groove cuts off the light path between the left optical fiber and the right optical fiber, after the signal of which the light path is cut off is fed back to the fire disaster alarm controller by the optical fiber, the fire disaster alarm controller changes a red LED light source which flashes at a certain frequency into red normally-bright light after the signal is processed, and the red normally-bright light is LED to the warning fiber hole through the warning optical fiber to be used as a response indication of starting manual warning.
When fire disaster is relieved, the light path between the left optical fiber and the right optical fiber is restored to be normal, after signals of the normal light path are fed back to the fire disaster alarm controller, the fire disaster alarm controller changes normal light back into flash light after signal processing, and finally the reset cover plate is slid upwards to realize reset.
The traditional manual fire alarm button transmits an electric signal to the fire alarm controller through the copper wire so as to start the audible and visual alarm for alarm.
