Cold Weather Exit Signs
Cold weather exit signs are built to operate reliably in extreme low-temperature environments. These UL 924 listed signs use long-life LED illumination and feature internal battery heaters in a sealed housing that resists freezing and condensation.
- UL 924 Compliant
- -40°F Operation
- 90-Min Battery Backup
- Heated Battery Compartment
- Directional Arrows
Common applications include walk-in freezers, refrigerated warehouses, outdoor egress points, and other areas where standard exit signs fail due to battery freeze or brittle components. Every model includes a battery backup for 90-minute emergency operation, ensuring full life-safety compliance even when temperatures drop.
These units typically include internal battery warmers, field-selectable chevrons, and self-testing diagnostics to simplify inspection and reduce maintenance in harsh climates.
Whether you’re retrofitting a refrigerated warehouse or installing signage for an outdoor escape route, cold weather exit signs deliver dependable performance in subzero conditions. If you need more customization options, you can explore additional emergency exit sign features to match your application.
What does “cold weather rated” mean? These fixtures are specially engineered for environments that experience freezing temperatures. They include heating elements and weather-sealed electronics to ensure reliable illumination down to -40°F.

FAQs About Cold Weather Exit Signs
What qualifies as a “cold weather” rated exit sign?
These are exit signs engineered to operate in environments as cold as -40°F, using internal battery warmers and sealed housings to prevent freezing failures.
Are these fixtures UL 924 compliant?
Yes. All cold-weather exit signs are UL 924 listed and meet life safety codes such as NFPA 101 and OSHA emergency egress requirements.
What makes a unit suitable for freezing temperatures?
Features like thermostatic battery heaters, cold-rated Ni-Cd batteries, and gasket-sealed electronics ensure reliable function in sub-freezing environments.
Do these include battery backup?
Yes. All models include a 90-minute battery backup that remains functional in extreme cold, thanks to internal thermal protection systems.
Are LED and self-testing versions available?
Absolutely. Most models use energy-efficient LED illumination and offer self-testing diagnostics to simplify code compliance and reduce manual inspections.
Where should I install cold weather-rated exit signs?
They’re ideal for walk-in freezers, refrigerated warehouses, unheated stairwells, outdoor access points, and loading docks—any location exposed to freezing temperatures where standard signs may fail.
