The Booster Power Supply (BPS) is a UL 864, 9th edition listed power supply. It is a 24 VDC filtered-regulated and supervised unit that can easily be configured to provide additional notification appliance circuits (NACs) or auxiliary power for Mass Notification/Emergency Communication (MNEC), as well as life safety, security and access control applications. The BPS contains the circuitry to monitor and charge internal or external batteries. Its steel enclosure has room for up to two 10 A-hour batteries. For access control-only applications, the BPS can support batteries totaling up to 65 A-hours in an external enclosure. The BPS has four class B (convertible to two Class A) NACs. These can be activated in one or two groups from the BPS's unique dual input circuits. The BPS is available in 6.5 or 10 A models. Each output circuit has a capacity of three amperes; total current draw cannot exceed the unit's rating.
