To provide a secondary power supply for a fire alarm system, you can use an emergency generator designed, installed, and maintained in accordance with NFPA 110, Standard for Emergency and Standby Power Systems. This generator provides power to the fire alarm system through an automatic transfer switch.
Fire alarm batteries are typically located within the fire alarm control unit enclosure, or in a separate battery box near the fire alarm control unit. They provide a secondary power supply, most commonly in the form of a Valve-Regulated Lead-Acid battery.
Fire alarm batteries need to be sized to provide power to the entire system for 24 hours in standby and 5 minutes in alarm. If the system is an emergency voice alarm communication system (EVACS), then the batteries need to provide capacity for 15 minutes in alarm in addition to the 24 hours in standby.
Two backup batteries are required with the APS Series power supply. The largest batteries that can fit in the power supply enclosure are 24 Ah. When using batteries larger than 24 Ah, they must be installed in a BC-1 or BC-2 battery cabinet.
The sense input circuits on APS Series fire alarm power supplies can be connected to 12 VDC or 24 VDC systems. For details about device compatibility, refer to Remote Booster Power Supply Compatibility List (P/N 3100656). Follow these steps to install and set up the APS Series power supply.
APS Series power supply. Remove the power supply’s ground fault jumper. See “Ground fault detection jumper (JP3)” on page 15. JP4 determines the amount of current that the battery charging circuit uses to charge the standby batteries. See Figure 11 below. Battery charging current is 1.5 A. Use to charge standby batteries that are 10 Ah and smaller.
