Should fire protection maintenance be suspended if the hotel is closed?

No need. According to relevant public information inquiries, maintenance and repairs of large equipment can be arranged during the shutdown period, especially maintenance projects that will affect operations during business operations, such as power generation systems, vulnerability systems, fire protection systems, etc. You should fully understand the details that need to be paid attention to before and during the shutdown of various large-scale electromechanical equipment, and when they are restored to use, to avoid losses caused by improper operation of the equipment during this period (you can consult equipment after-sales maintenance or service personnel).
