Cold Weather Exit Sign Combos – Heated, Weatherproof Egress Solutions
Cold weather exit sign combos integrate illuminated EXIT signs with emergency lighting heads and internal battery heaters, ensuring reliable operation in freezing environments—from −4 °F down to −40 °F. These units are fully UL 924 and NFPA 101 compliant and ideal for cold storage, ski resorts, freezer areas, and outdoor applications.
Constructed with rugged, gasketed polycarbonate or PVC housings and NEMA-rated weatherproof exit sign enclosures, they withstand ice, moisture, and corrosion. Dual-voltage (120/277 VAC) heating pads keep the battery warm to ensure a full 90-minute emergency runtime in extreme cold.
Typical models feature bright red or green LED EXIT legends, sealed incandescent or LED lamp heads, push-to-test switches, and optional self-testing diagnostics. Field-selectable chevrons and universal mounting options make them versatile for wall, ceiling, or pendant installations.
