Fire Alarm Battery


Fire Alarm Battery


A commercial fire alarm system must be equipped with an optional backup fire alarm battery in the event of power failure. A fire alarm battery features rechargeable 12 volt DC sealed lead acid batteries. Even though, the alarm battery is 12 volts, it is available in 4, 6, 8, and 12 amp hours. The more amp hours the battery, the longer it last. Most fire systems take a least two batteries while some take many more.
