Henan real estate spray

The indoor automatic sprinkler system is integrated with the building. It belongs to the owner of real estate and is managed by the property management department. Some units with their own property rights are managed by themselves, not necessarily by external property management. It depends on how the owner decides when signing a contract with the property. The owner basically does not maintain it, but a fire engineering company does "maintenance" (repair) because this system is a combination of alarm system and sprinkler system. Professionals should be on duty 24 hours a day. The doorman only knows what's wrong with the system, but he can't handle it, so it's usually the fire engineering company installed at that time to do the later "maintenance".
