The skylight ceiling controller is abnormal, what should be done?
1) If the data center catches fire, put out fire immediately.
2) If the data center is free from fire, the smoke detector or the heat detector is faulty. Check that the cables to the smoke detector and the heat detector are connected properly.
3) After verifying that the data center is free from fire and that cables are connected properly, disconnect the skylight ceiling controller from the power supply to reset the smoke detector and heat detector. After smoke vanishes and the temperature drops to the normal, reconnect the skylight ceiling to the power supply.
