What term describes an on-site normal supply of electric power that is expected to be constantly producing power?

• A. On-Site Power Production Facility
• B. Standby Power
• C. Emergency Power
• D. Backup Generator

Answer: (A)

The idea is distinguishing the different sources that feed a fire protection system. When a power source is described as the on-site normal supply that is expected to be constantly producing power, it points to a facility located on the site specifically designed to provide power continuously as the normal, primary source. That is an on-site power production facility. It means the system is built to rely on this on-site generation for normal operation, without waiting for utility power or for an outage to trigger a backup.

Standby power, by contrast, is meant to take over only when the normal source fails. Emergency power is intended to keep essential safety loads operating during a loss of normal power, not as the continuous normal supply. A backup generator is a general term for a generator used to provide power during outages, rather than describing a facility whose purpose is to permanently deliver normal power on-site.
