Battery Backup Exit Signs – Code-Compliant Egress Visibility When Power Fails

Battery backup exit signs play a vital role in any life safety system, providing illuminated egress guidance during power outages. These fixtures are required in most commercial, industrial, and institutional buildings to ensure occupants can find their way to safety under low-light or emergency conditions. All models are UL 924 listed and compliant with NFPA 101 and OSHA emergency lighting standards.

Our selection includes high-efficiency LED exit signs equipped with internal batteries capable of delivering at least 90 minutes of illumination during a loss of power. Built-in solid-state chargers and automatic transfer circuitry ensure a seamless switch to emergency mode. Many models also feature self-testing diagnostics to reduce manual inspections and keep you compliant with routine testing protocols.

Fixtures are available in both single-face exit sign and double-sided exit sign configurations, with universal mounting hardware that supports wall, ceiling, or end installations. Field-selectable directional arrows (chevrons) make it easy to adjust signage orientation on-site, while red and green LED legend options accommodate regional and aesthetic preferences.

Whether you're securing an office building, warehouse, school, or multi-unit residential space, battery-powered exit signs ensure reliable egress visibility and code adherence during emergencies. For a complete emergency lighting system, consider pairing these signs with LED emergency light fixtures to provide full-path illumination throughout your facility.

From basic thermoplastic models to premium finishes with tamper-resistant features and wet-location ratings, battery backup exit signs offer flexible solutions for a wide range of building types and safety requirements.

Most models use sealed Nickel-Cadmium (NiCd), Nickel-Metal Hydride (NiMH), or Lithium-ion batteries for reliable long-term use and fast recharge cycles.

❓ Are battery backup exit signs hardwired?

Yes. These fixtures are typically hardwired into the building's electrical system and automatically switch to battery power when AC fails.

❓ Do battery backup signs require regular testing?

Yes. Monthly 30-second tests and annual 90-minute full discharge tests are required. Self-testing models automate this process.

❓ Can battery backup exit signs be used outdoors?

Only if they are UL listed for wet environments. Standard models are for indoor use unless otherwise specified.

❓ What mounting options are available?

Most signs support universal mounting — wall, ceiling, or end — and include adjustable mounting brackets and field-selectable directional arrows.
