Can the hotel smoke alarm be powered off?
At present, most of the smoke alarms used in hotels are photoelectric.So power cuts don't affect the product.However, for the safety of customers, it is recommended 24 hours to electrify.
The smoke alarm installed in the hotel is connected to the fire alarm host, which is powered by the main line through the weak line. It is not the alternating current, so it can not be cut off from the hotel guest room.
