What to Look for in Battery Backup Exit Sign Combos

  • UL 924 & Runtime: Verified 90-minute battery backup and compliant egress illumination.
  • Battery Chemistry: Ni-Cd vs. Li-ion/LiFePO4 for weight, recharge, and lifecycle.
  • Legend & Faces: Red/green letters, field-selectable chevrons, single or double face.
  • Photometrics: Adjustable LED heads to hit corridor spacing and foot-candle targets.
  • Mounting: Universal wall/ceiling/end mounting hardware and canopy.
  • Environment: Damp/wet-location ratings or cold-weather packages as needed.
  • Diagnostics: Self-testing exit sign combos for automated monthly/annual checks.
Why choose a battery backup exit sign combo? One fixture delivers both egress signage and emergency lighting—reducing fixture count and wiring while keeping your site code-ready during outages.

Each combo includes an LED EXIT faceplate (red or green), field-selectable chevrons, and adjustable emergency heads driven by a shared internal battery and solid-state charger/transfer circuit. This unified design simplifies installation and service while maintaining required light levels along paths of egress in stairwells, corridors, and utility spaces.

Most models ship with universal mounting hardware for wall, ceiling, or end installations and offer single- or double-face configurations. For outdoor or wash-down areas, choose wet-location exit sign and emergency light combos; for harsh industrial environments, consider sealed NEMA-rated emergency lights.

Self-testing availability and temperature ratings vary by model—confirm diagnostics, runtime, and accessories on the product specification sheet.
