It is important that critical emergency systems that support fire sprinklers, alarms and pumps continue to remain operational for the entirety of evacuation and firefighting efforts.
Protecting building occupants and first responders is critically important when designing and constructing commercial buildings. The National Fire Protection Association (NFPA), devoted to eliminating death, injury, property and economic loss from fire, electrical and related hazards, was formed in 1896. Shortly afterward, in 1897, the National Electrical Code (NEC) was established to standardize electrical safety for wiring, alarms and related equipment. Since the birth of these two important standardizing organizations, fire codes have been constantly modified to meet the changing safety needs of new infrastructure.
In 1996, the NEC identified key circuits for fire survivability, including emergency systems, fire pumps and fire alarms. Per the 1996 code, these circuits needed to be able to survive for one hour in case of fire. However, in the late 1990s and early 2000s, these requirements began to shift to demand two hours of survivability.
