The Power Sonic PS-1250 F1 is a 12V, 5.0 Ah sealed lead acid (SLA / VRLA) battery. Specifically, it ships with F1 (0.187″ / 4.75 mm) quick-disconnect tabs. First, it supplies standby power for fire alarm and security panels, UPS, and emergency lighting. Then, the AGM construction allows mounting in any orientation.
How the Power Sonic PS-1250 F1 is used
Therefore, technicians specify this size when a panel calls for a 12V/5Ah SLA on light-cyclic or float duty. Also, F1 tab terminals match standard quick-connect leads on most panel battery cables. In addition, the AGM design is non-spillable. As a result, the PS-1250 F1 fits commercial fire panels, security panels, and small UPS systems.
