The Edwards EBPS6A is a 6.5 amp Remote Booster Power Supply for fire alarm Notification Appliance Circuits. First, it expands the NAC capacity of an existing fire alarm control panel. As a result, you can power more horns, strobes, and speakers from a single system.
Edwards EBPS6A architecture
The unit ships with four independent Class B NACs that convert to two Class A circuits via jumper. Each circuit handles up to 3.0 A. In addition, the four NACs share a 6.5 A total budget. Furthermore, NACs 1 through 4 can be reconfigured as auxiliary 24 Vdc outputs. Also, a dedicated 200 mA auxiliary output is included for accessory power.
Signal coordination and synchronization
The EBPS6A generates three signal rates internally. First, continuous tone for steady horns. Then, the 3-3-3 temporal pattern required by NFPA 72 for fire evacuation. Alternatively, the booster can follow the host panel’s NAC signal rate. As a result, it provides Genesis strobe and horn synchronization without a separate sync module.

Status indication and supervision
Seven on-board LEDs report system health. Specifically, one LED per NAC, plus battery, ground fault, and AC power indicators. As a result, troubleshooting is fast without test gear. Furthermore, fault conditions detected by the EBPS open the host panel’s NAC for centralized annunciation.
