Battery Backup Exit Sign and Emergency Light

Battery backup exit sign and emergency light combos offer a dependable all-in-one solution for life safety. These compact fixtures illuminate the exit path and provide egress lighting for 90 minutes during power failure—ensuring compliance with UL 924, NFPA 101, and OSHA regulations.

Each unit features an internally illuminated LED exit sign combo with field-selectable directional chevrons, along with adjustable emergency lamp heads powered by a shared battery backup system. These models are ideal for stairwells, corridors, utility rooms, and multi-use commercial spaces.

Most options support universal mounting for ceiling or wall installation, and are available in single- or double-face configurations. For maintenance efficiency, many fixtures also offer built-in self-diagnostic systems that automate code-required testing.

Why choose a combo unit? Battery backup exit sign/emergency light combos simplify installation and code compliance by combining two essential safety functions into one fixture—reducing labor, wiring, and maintenance costs while enhancing reliability.

Whether you’re upgrading an existing building or installing new egress signage, battery backup combo units provide safety, efficiency, and peace of mind in one easy-to-install fixture.
