AC Wiring – Primary
Robust power, simple installation
When you want an all-in-one emergency solution, our emergency fixtures featuring driver-powering backups take the hassle out of installation and maintenance. They’re ideal for fixtures that are installed in a plenum, such as downlights, and feature built-in test buttons/indicator lights as part of a fully integrated solution.
AC Wiring – Primary
Fully enclosed solutions that combine battery and emergency driver into a single unit for easier installation. The emergency backup powers the driver, not the LEDs directly, making it more appropriate solution for certain lighting types. These units offer 90-minute operation in Emergency Mode.


AC flying leads: Flexible and fast
Flying leads are ideal for fast and flexible installation, allowing you to incorporate emergency lighting solutions into a wide range of LED fixtures. All Keystone units come with a 2-in-1 test switch/indicator light, and are compatible with Keystone products.
AC conduit: Security and durability built in
Conduit shields wiring from environmental hazards, ensuring durability and compliance with safety codes. If working with sealed or integrated fixtures like downlights or LED tubes, or in a code-sensitive space, conduit is a must. Keystone conduit-equipped backups are ideal for rough service or open installations, and compatible with Keystone products including Aviva and Circa downlights, and Keystone compact lamps.


Special purpose: Round high bay emergency
Our SmartSafe LED Emergency Backup Driver for Round High Bays is specifically designed for our round high bay. With fixture, power supply, and backup from the same manufacturer, you can trust they’ll work together immediately, saving on evaluation and maintenance.
DC Options
Keystone has a variety of DC options available, including backups with flying leads, conduit, and standard terminal block, as well as special purpose backups and models featuring our autoBC technology.
