MaxPower Corp FirstLine 924 8, 12, 16kW - Manual (Page 2)

Applications
■ Public Buildings
■ Theaters
■ Schools
■ Parking Garages
■ Housing Complexes
In the event of an AC power failure, FirstLine ® 924
automatically supports the connected lighting loads on
battery power and will continue to provide power without
any interruption for a full 90 minutes. When the utility power
returns to normal, FirstLine
® 924 will automatically recharge
the batteries to be ready for the next power disturbance.
