Question: Bidding on large complex with below grade parking garage. Do the 2 head emergeny lites have to be a special type, for outdoor cold temps, or will the same type work that are generally installed in doors. Can't find a temperature rating on my normal type.
Emergency Lighting for Below-Grade Parking Garages
Yes, the 2 head emergency lights installed in below-grade parking garages require a special type designed for outdoor cold temperatures.
Temperature Rating
Emergency lights installed in outdoor or cold temperature environments must have an appropriate temperature rating. The minimum temperature rating required by the National Electrical Code (NEC) for emergency lighting in below-grade parking garages is -20°F (-29°C).
Type of Emergency Light
The type of emergency light suitable for outdoor cold temperatures is called a "Wet Location" emergency light. These lights are specifically designed to withstand moisture, snow, and extreme cold conditions. They are equipped with gaskets and seals to prevent water and moisture from penetrating the fixture.
Indoor Emergency Lights
Emergency lights designed for indoor use are not suitable for outdoor or cold temperature environments. They do not have the same level of protection against moisture and cold, and may not function properly in these conditions.
Conclusion
Therefore, it is crucial to select the appropriate type of emergency light with a suitable temperature rating for outdoor cold temperature environments in below-grade parking garages. This ensures that the lights will function reliably in the event of a power outage and provide adequate illumination for safe evacuation. Flag for review
