Fire Smoke Exhaust Skylight undertakes the extremely important task of exhausting smoke and dissipating heat when a fire occurs. Its normal operation is related to the life safety of personnel and the fire safety of buildings. The following are the key steps and points for debugging Fire Smoke Exhaust Skylight to ensure its effective operation in the event of a fire.
Before debugging, it is necessary to fully check the installation of the equipment. First, confirm that the window frame of the Fire Smoke Exhaust Skylight and the reserved opening of the building are well sealed and there are no air leakage gaps. The smoke test method can be used for preliminary inspection. Check the transmission mechanism of the skylight, including the motor, reducer, chain, push rod and other components, to ensure that the connection is firm, without looseness or jamming, and apply an appropriate amount of lubricating oil to ensure smooth operation. At the same time, verify whether the installation position and wiring of the electric actuator are correct. It should be able to receive the fire control signal and act accurately.
Then perform a power-on test. Connect the power to the Fire Smoke Exhaust Skylight, operate the control switch, check whether the opening and closing of the skylight is flexible and whether the opening angle meets the design requirements. Generally, it is required to reach the maximum opening angle to achieve the best smoke exhaust effect. During the opening and closing process, observe the running sound and current changes of the motor. If there is abnormal noise or excessive current, it is necessary to stop the machine immediately to check the fault. It may be a motor failure, obstruction of the transmission components or electrical circuit problems.
After completing the power-on test, linkage debugging is required. Connect the Fire Smoke Exhaust Skylight to the fire control system of the building, simulate the fire signal, such as triggering the fire alarm detector or the manual alarm button, and observe whether the skylight can be automatically opened within the specified time. Generally, it is required to complete the opening action within 60 seconds. At the same time, check whether other equipment linked with the Fire Smoke Exhaust Skylight, such as smoke exhaust fans, fireproof roller shutters, etc., work together to ensure the integrity and coordination of the entire fire smoke exhaust system.
The last step is the performance test. Using professional anemometers, wind flow meters and other equipment, measure the smoke exhaust volume and wind speed of the Fire Smoke Exhaust Skylight when it is turned on, and compare them with the design standards. If the requirements are not met, the blade angle and ventilation area of the skylight need to be adjusted and optimized. In addition, weather resistance tests are required to simulate different climatic conditions, such as high temperature, heavy rain, and strong winds, to check the sealing performance, structural strength of the skylight, and the waterproof and windproof performance of the electrical equipment to ensure normal operation in various harsh environments. Only through the above rigorous debugging process and comprehensive test items can the Fire Smoke Exhaust Skylight be guaranteed to operate stably and reliably during a fire to the greatest extent, providing a solid guarantee for building fire safety.
