Asenware AW-D121C(2.5A) Conventional System Power Supply Box 2.5 A

AW-D121C(2.5A) is a battery-backed power supply box with 2.5 A output current used for powering auxiliary devices in fire alarm installations. When mains power is interrupted, batteries installed inside the box are activated to allow connected devices to continue operating. It is preferred to power the circuit from a separate source in installations where the panel's own output is insufficient and carries additional loads such as sirens, flashers, door magnets, and relay modules. Its box form facilitates mounting by securing it to the wall next to a field panel or floor distribution point. A 3 A output version of the same family is also available; after the project's total load is calculated, the appropriate model should be selected from the two options.
