With Keystone’s autoBC design feature, the emergency fixture reaches the job site pre-wired and ready to go — just connect to current and autoBC will engage the battery. It’s included in our Back-Lit Panel with Integrated Emergency Backup, and standard on a variety of our 10W SmartSafe backups.

DC conduit: Emergency backup for core commercial fixtures
