Product Description
900-BBK Von Duprin Battery Backup Kit — Complete with Batteries
Expert's Note: The 900-BBK is the complete battery backup solution — board plus two 7A/hr batteries in one kit. When the building loses AC power, this keeps your electrified exit devices operational for up to 4 hours depending on load. Required by code on most fire-rated and life-safety applications. If the power goes out and the doors fail, you've got a code violation and a liability problem. This kit prevents that.
If you already have the battery board from a previous install and just need fresh batteries, order the 900-BAT instead. If you need just the board (you have batteries), order the 900-BB.
