Central Station Fire Alarm Systems
Secondary power will consist of either storage batteries, a combination of storage batteries that "float" on the system and an automatic generator, or multiple generators, one of which must start automatically. The generator supplies must be on a dedicated branch circuit.
There is almost no difference in the requirements or type of batteries used in a central station compared to a protected premises fire alarm system.
The requirements for generators are more stringent, given the fact that there has to be a reliable backup power supply for a central station and that any generator arrangement must be reliable. If there is a single automatic starting generator, with float batteries, the generator installation and arrangement must conform to NFPA 70, National Electrical Code, article 701. If multiple generators are used, article 702 applies.
