Incandescent bulbs were used to light the first exit signs, and this type is still common in commercial buildings due to the low cost of the bulbs. But unfortunately, incandescent bulbs burn out rapidly, require a lot of energy, and give off heat. And importantly, these are the same bulbs phased out by the Energy Independence and Security Act 2007.
The initial cost of an LED exit sign may be slightly greater, but the savings in maintenance, energy, and overall performance far outweigh the effort.
The following are some essential things you should be aware of about exit signs:
- How often should I make sure my emergency lights and exit signs are working correctly?
You are obligated by law to do regular inspections and testing of your emergency exit and lighting systems. The NFPA 101 Life Safety Codes recommend that Emergency Lighting Units be tested every 30 days for 30 seconds and every year for 90 minutes.
- How can I check the status of the exit signs in my building?
You can find a small “Push to Test” button on non-self-testing machines, which will shut off the power to the device and put it into emergency mode when pressed. Use this button to check the bulbs and batteries once a month as part of your maintenance.
Holding the test button for thirty seconds should ignite the light or sign and keep it bright. If it does, your device has passed the test. An electrician will be needed to troubleshoot if the lights dim or do not turn on.
- How long does an exit sign should STAY ON?
The NFPA 101 Life Safety Code mandates that the light is on for at least 90 minutes after the power goes off and the emergency mode is activated.
- What’s the best color for the exit signs?
Regarding Exit Signs, there are two preferred color options in the United States: Red or Green. However, red is usually the safer option. Additionally, building codes in many states and cities define the color sign that must be used.
You can also ask the Fire Marshall or Inspector of your city to assist you in choosing the appropriate exit sign color.
- Can I save money on my energy cost by purchasing a new LED exit sign?
Possibly, yes. LED exit signs need less power than incandescent bulbs or traditional lighting, so upgrading an outdated light will help you save money on your energy bill. Consider using power-free exit signs such as tritium or photoluminescent or upgrading your exit signs with LEDs instead of traditional ones.
- What are the different kinds of exit signs available?
Low-power LEDs, with power backup, incandescents, halogens, and other types of lighting are available commonly. Look for the product info when looking for emergency or exit signs to see what kind of illumination each one employs.
LED exit signs with battery backup, the electricity is not necessarily required. Instead, other energy sources provide illumination for them. An internal battery is used to power the exit sign in the event of a power loss. For the battery to work in Emergency Mode, these LED exit signs with battery backup must be hard-wired into your building’s electrical system. In a power outage, they will also keep the exit signs illuminated for the span of 90 minutes.
