This standard covers performance requirements for emergency and standby power systems providing an alternate source of electrical power in buildings and facilities in the event that the normal electrical power source fails. These systems are known as level 2 or less critical systems. An emergency power system is an independent source of electrical power that supports important electrical systems on loss of normal power supply.

Emergency power systems provide automatic backup power in the event of normal power loss. In the united states backup power systems are governed by nfpa 110 standard for emergency and standby power systems.

Ats selects between the normal power grid and emergency generator.

Emergency and standby power systems are a sign of attentiveness to unpredictable situations such as natural disasters and other events that can take down electrical systems. Systems include power sources transfer equipment controls supervisory equipment and accessory equipment needed to supply electrical power to the selected circuits. The machinery that keeps electricity going can save lives. Simply put anything that will protect the lives of the building occupants should be on emergency power.
