There is no time for “getting set”. The biggest challenge with emergency power generation and a standby emergency fire pump is that it must start every time, no exceptions. They must be up to speed within seconds. To achieve this kind of critical reliability, systems must be continually tested and serviced.
Retailers, especially those with refrigeration units, want to be assured of controlled temperatures in the event of a power failure. They are also concerned for safety if the lights suddenly go out; a concern shared by apartment and other community property managers. Manufacturers know that a production line can be shut down and expensive equipment can be damaged if power is interrupted. In areas not connected to community water systems, emergency fire pumps must also always be ready. Healthcare facilities must be sure that critical systems are always running
