Battery Backup Exit Signs

Battery backup exit signs provide critical egress visibility during power outages, ensuring that occupants can safely exit the building even in low-light or emergency conditions. These fixtures are a requirement in most commercial and industrial spaces, helping meet UL 924, NFPA 101, and OSHA life safety codes.

Our selection includes energy-efficient LED models with internal batteries that deliver a minimum of 90 minutes of emergency illumination. Many units feature self-testing diagnostics, reducing the need for manual inspections and streamlining compliance with monthly and annual testing standards.

Fixtures are available in single- or double-face configurations with universal mounting hardware for wall, ceiling, or end installations. Field-selectable chevrons make it easy to configure directional signage on-site, and most models offer red or green legends to meet regional code requirements.

Whether you're outfitting an office, warehouse, school, or multi-tenant building, battery backup exit signs ensure uninterrupted safety and legal compliance. For full system coverage, pair with our emergency lighting units.
