What is the maximum time allowed for a generator to provide power to a fire system alarm?

The maximum time allowed for a generator to provide power to a fire alarm system is 60 seconds. This requirement is critical because fire alarm systems must maintain functionality during power outages to ensure the safety of occupants. A generator needs to start and assume the load within this timeframe to ensure that there is no disruption in monitoring or alerting in the event of a fire.

If a generator takes longer than 60 seconds to provide power, it could lead to a situation where the fire alarm system is inoperative during critical moments, potentially endangering lives. Depending on local codes and standards, including the National Fire Protection Association (NFPA) guidelines, this limit ensures that the fire alarm systems remain reliable and effective in emergencies. This specification exemplifies the commitment to maintaining safety standards in high-rise buildings, as fire alarms are essential life safety systems.
