Power Over Ethernet lighting works with UL listed emergency systems
FAMA’s Smart Traffic Signal Control and Ground Luminous Sign Series show how new ideas make safety and emergency help better.
Active luminous signs are very bright all the time. They help people find exits fast in emergencies. These signs work well in dark or smoky places.
Photoluminescent exit signs glow after they soak up light. They are good when the power goes out. These signs are easy to take care of. They are a safe and dependable choice.
Reflective signs need outside light to be seen. They work best outside. They may not help in emergencies if there is no light.
All sign types need regular checks and care. This makes sure they work right and are safe. It helps keep everyone protected.
Facility managers should pick signs for their space. Internally Illuminated Signs are good for busy places. Photoluminescent signs are better for inside areas.
Emergency signs help people find safety in dangerous times. There are three main things that make signs work well. First, they must be easy to see when it is dark. Second, they need to work if the power goes out. Third, they must follow safety rules. FAMA works hard to make sure their signs do all these things.
People need to see signs to find exits and safe paths. This is very important when lights are dim. Signs should be clear from many angles and far away. Bright materials and strong color differences help people see them. Signs should not shine or reflect too much light. White backgrounds with red or green letters are best. Letters should be at least six inches tall. More signs can help people in big or tricky places.
Tip: Put signs where people can see them easily and where there is enough light.
Signs must work even if the lights go out. Battery backups keep signs bright when power fails. Emergency lights should work even if there is smoke or fire. Signs should not only depend on the building’s power. Batteries can fail, and wires can break. This can make it hard to find the way out. Checking signs often helps keep them working right.
Key Feature | Description |
Reliability | Battery backups keep signs bright when the power is out. |
Visibility | Signs should be easy to see from many places. |
Following safety rules keeps people safe and avoids problems. Groups like NFPA, OSHA, and ANSI make rules for signs. These rules say where to put signs and how big they should be. Signs must have letters that are tall and wide enough. Signs need to be checked and tested often. If people forget to check, signs might not work. Rules from other countries, like ISO 3864 and ISO 7010, help make signs look the same everywhere. FAMA’s signs follow these rules to help keep everyone safe.
Note: Check signs often and keep good records to make sure they work and follow the rules.
An active luminous sign has its own lights inside, like LEDs. These signs do not need sunlight or other lights to work. They glow by themselves, so people can see them day or night. The technology uses LEDs that save energy, smart circuits, and strong materials. These signs can show many colors and shapes. This helps people notice important messages fast.
Engineers pick an active luminous sign for places like airports and stores. These signs are very bright and light up evenly. Every letter and symbol is easy to see, even from far away. The colors stay bright and do not fade. Companies can make special designs for their needs. FAMA uses these signs in their Smart Traffic Signal Control and Ground Luminous Sign Series. This helps keep people safe and shows them where to go in busy places.
Feature | Active Luminous Signs | Non-Illuminated Signs |
Visibility | Enhanced visibility day and night | Limited visibility |
Distance | Can be seen from further away | Less effective at distance |
Design Flexibility | High flexibility in design and placement | Limited design options |
Energy Efficiency | LED signs are energy efficient | N/A |
Cost | Generally lower for LED options | Higher for traditional types |
An Internally Illuminated Sign has many good points for emergencies and daily use:
People can see the sign from far away, even in bad weather.
The sign works all the time, even if the area is dark.
Custom shapes and messages are easy to create.
The sign uses less energy, which saves money.
The sign stays bright and clear for many years.
In emergencies, an Internally Illuminated Sign does not need backup lights. It stays bright if other lights stop working. The sign gives clear signals, so people stay calm and find exits faster. It also helps people find fire equipment and safe paths, even if there is smoke.
Note: Check each Internally Illuminated Sign often to make sure it works well and is ready for any emergency.

Photoluminescent exit signs use special materials to store energy. These materials soak up light from lamps or sunlight. When it gets dark, the signs glow using the stored energy. This glow helps people see the signs if the power goes out.
The science behind photoluminescent exit signs is easy to understand:
Principle | Description |
Energy Absorption | Photoluminescent materials take in light from lamps or the sun. |
Gradual Release | These materials slowly let out the stored energy as light in the dark. |
Duration of Illumination | Good signs can glow for up to 12 hours after getting charged. |
Independence from Electricity | Photoluminescent exit signs do not need electricity, so they work when the power fails. |
Photoluminescent technology uses phosphorescent materials. These materials keep glowing for a long time if they get enough light. How well the signs work depends on the quality of the materials and how much light they get.
Photoluminescent exit signs have many good points in emergencies. They do not need batteries or wires to work. The signs keep glowing even if the building loses power. People can count on these signs to help them find the way out. Photoluminescent exit signs also work well in smoky places, like during fires.
Studies show photoluminescent exit signs perform well in different situations:
Type of EWS | Condition | Performance Rating |
Passive Photoluminescent | Lights-On | Higher Rating |
Passive Photoluminescent | Lights-Off | Higher Rating |
Passive Photoluminescent | Smoke | Higher Rating |
Facility managers pick photoluminescent exit signs because they are reliable and simple to care for. These signs do not need battery checks or electrical repairs. People can see the glow from many angles, which helps everyone find exits fast. Photoluminescent exit signs work well in schools, offices, and public buildings. They help save lives by showing clear paths to safety.
Tip: Put photoluminescent exit signs where they get enough light during the day for the best glow in the dark.
Reflective signs help people by sending light back to where it came from. These signs use special materials that make them easy to see when a light shines on them. The two main materials are glass beads and microprismatic sheeting. Glass beads let light go in, bend, and bounce off a shiny surface. This sends the light back to the person with a flashlight or someone driving a car. Microprismatic sheeting uses tiny prisms to reflect light better. This material sends light back in a straight line, so the sign looks bright from many angles.
Here is a table that shows how these materials work and how well they perform:
Material Type | Mechanism of Operation | Performance Characteristics in Lighting Conditions |
Glass Beads | Light goes in, bends, and bounces off a shiny surface, going back to the source. | Works well when it is dry; rain can make the light scatter. |
Microprismatic Sheeting | Tiny prisms reflect light well, making it leave in a straight line. | Makes the sign bright from many angles and gives a bigger bright area. |
Reflective signs do not glow-in-the-dark by themselves. They need a light, like headlights or a flashlight, to be seen. People often see these signs on roads, in parking lots, and outside where cars or people have lights.
Reflective signs have some problems when there is not much light. In dark places, these signs cannot glow-in-the-dark unless there is a light. They need a beam of light to show their message. If the power goes out or there is thick smoke, people may not see the sign unless they have a flashlight or another light.
The table below compares different types of signs and what they are good at and not good at:
Type of Sign | Strengths | Limitations |
Photoluminescent | Does not need power, good for inside use | Needs light to charge; gets dim in total darkness |
Retroreflective | Good for outside or special use | Needs a light to be seen; does not work without it |
Hybrid | Uses both types for better visibility | Only works well if put in the right place |
Glow-in-the-dark signs, like photoluminescent ones, can help in places with no light. Reflective signs cannot glow-in-the-dark alone, so they may not work well in emergencies without extra light. Facility managers should think about these problems when picking signs for safety.
Tip: Use glow-in-the-dark signs in hallways, stairs, or places where the power might go out. Reflective signs are best where headlights or flashlights are always used.
A comparison summary helps people pick the safest emergency sign. This part looks at how Internally Illuminated Signs, photoluminescent signs, and reflective signs work in real emergencies. It also shows how FAMA’s Ground Luminous Sign Series adds new safety and follows rules.
Power outages can happen during storms or fires. People need clear signs to find exits fast. Active luminous signs have built-in lights like LEDs. They stay bright even if the power goes out. Many have backup batteries or solar panels. These signs are easy to see in total darkness. Photoluminescent signs glow after soaking up light from lamps or the sun. They do not need wires or batteries. People can see them in tunnels and stairwells. But they must get enough light before an emergency. If the power is out for a long time, these signs may get dim. Reflective signs need a flashlight or headlights to be seen. In a blackout, they do not work unless someone shines a light on them.
Studies show photoluminescent signs glow on their own during blackouts. They store energy from light and shine in the dark. Reflective signs do not work without a light source. Internally Illuminated Signs, like solar-LEDs, are the brightest but need battery checks. In short, active luminous and photoluminescent signs help keep people safe during power loss. Reflective signs do not help in blackouts.
Tip: For the best safety in blackouts, use active luminous or photoluminescent signs in important places.
Fires make smoke that blocks normal lights and makes it hard to see. People must find exits quickly to stay safe. Active luminous signs shine through smoke because they have strong lights inside. These signs use LED technology to stay bright in smoky places. Photoluminescent signs glow in the dark, but their brightness depends on how much light they got before the fire. They work well if charged, but thick smoke can make them dim. Reflective signs are hard to see in smoke and fire. They need a direct light, which is rare in emergencies.
The table below shows how each sign type works in smoke and fire:
Sign Type | Visibility in Smoke/Fire Conditions | Key Features |
Illuminated Signs | High | Internal lighting, visible in low-light, uses LED technology. |
Photoluminescent Signs | Moderate | Glows in the dark, no power needed, depends on prior light exposure. |
Reflective Signs | Low | Needs external light, less effective in smoke or fire. |
Internally Illuminated Signs give the best safety in fires. They help people see exits and fire equipment even when there is smoke. Photoluminescent signs help too, but only if they are well-charged. Reflective signs do not meet safety rules for indoor fires.
Note: Put Internally Illuminated Signs near exits, stairs, and fire equipment for the best safety.
Long-term reliability is important for safety and following rules. Active luminous signs use LEDs and smart circuits. They last many years with regular checks and battery changes. These signs work well in busy places like airports and shopping centers. Photoluminescent signs have no wires or batteries. They need little care and work well where there is steady light. Over time, their glow can fade if they do not get enough light. Reflective signs last a long time outside and cost less. They work best where headlights or flashlights are always used, like roads or parking lots.
Photoluminescent signs meet ISO and PSPA brightness rules. They do not need wiring or batteries, so they are easy to care for. Active luminous signs need more checks but work best in all conditions. Reflective signs are tough but do not help with indoor fire safety.
FAMA’s Ground Luminous Sign Series is a new and smart choice. These signs use advanced LED technology for strong, even light. They work in all weather and lighting. FAMA’s products meet strict safety rules. Real projects show their value in airports, tunnels, and city streets. To learn more, visit FAMA’s product page or see case studies.
What is a luminous sign? It is a sign with built-in lights that stays bright in all conditions. FAMA’s Ground Luminous Sign Series shows how this technology keeps everyone safe and follows the rules.
Facility managers and engineers think about how to put up and care for emergency signs. Internally Illuminated Signs need wires and special parts to be installed. Workers put these signs where people need to see them best. Teams check the batteries, LEDs, and circuits often to keep them working. Photoluminescent signs are easy to put up. Workers just hang them on walls or ceilings. They do not need any wires. These signs are simple to care for. Staff only need to make sure the signs get enough light to charge.
Reflective signs are also easy to install. Crews use bolts or glue to stick them to posts or walls. How often you need to replace them depends on the material and weather. The table below shows how long reflective signs last in different climates:
Sign Type | Mild Climate Replacement Interval | Harsh Climate Replacement Interval |
Engineer-Grade Sheeting | Every 5–7 years | Every 4–5 years |
High-Intensity Prismatic | Every 7–9 years | Every 5–7 years |
Diamond-Grade | Every 10–12 years | Every 7–10 years |
Active luminous signs might need more checks if the weather is rough. Photoluminescent and reflective signs last longer and do not need much care. Facility managers save time and money by picking signs that fit their weather and how they use them.
Tip: Check signs often to make sure people can see them and they follow the rules.
It is important to think about the environment when picking safety signs. Photoluminescent signs soak up sunlight during the day and glow at night. They do not use electricity, so they help save energy and lower pollution. Reflective signs also work without power. Both types help buildings be more green and earth-friendly.
Internally Illuminated Signs need electricity to work. LED lights use less energy, but these signs still use some power. In big buildings or outside, engineers pick models that save energy to help the planet. Studies show photoluminescent and reflective signs both use very little energy. They are good choices for places that want to be eco-friendly.
Facility managers pick signs by looking at energy use, how much care they need, and how they help the environment. Photoluminescent and reflective signs are good for saving energy and being green. Active luminous signs are very bright and have special features, which help keep people safe in hard places.
Note: Think about how much energy signs use and how often you need to check them when planning for new signs. This helps save money and helps the planet in the long run.
Picking the best emergency sign depends on where you are and what you need. FAMA says custom Internally Illuminated Signs are best for places that need high safety and visibility. These signs work great in malls, airports, and busy streets. They are very bright and can show different messages or flash in patterns. Studies from the Federal Highway Administration say active warning signs can cut pedestrian crashes by up to 40% in risky areas. Flashing crosswalk signs that can be programmed also make cities safer. Changing how the lights flash during busy times helps keep people safe when it is most needed.
Custom active luminous signs from FAMA are made for business owners and stores. You can pick your brand colors, logos, and special messages. These signs work inside and outside, even if the power goes out. FAMA makes sure each sign follows local and fire rules, so they are a good choice for any project.
Tip: Always pick the right sign for the place and make sure it follows all safety and fire rules.
Facility managers help keep everyone safe. They should do these things to make sure signs work well and follow the rules:
1. Mark exits and emergency tools clearly. Keep paths open and use signs that follow ANSI Z535 formats.
2. Make a list of safety data sheets (SDS) and check that all hazard signs have the right symbols and words.
3. Use colored floor markings and teach staff what they mean.
4. Put up notices for personal protective equipment (PPE) and controlled entry where needed.
5. Pick strong sign materials. Test them for UV, scratching, and chemical damage. Check local building codes for emergency exit sign lighting.
Facility managers should check signs often and change them if needed. This keeps the building safe and makes sure all signs follow the latest safety and fire rules.
Safety experts and facility managers pick active luminous signs for safe evacuations. FAMA uses real-time checks and matching warnings to help people leave tunnels, malls, and airports. Photoluminescent signs save energy and help people get out safely. Reflective signs help people evacuate outside. Facility managers say to use new signs for evacuation, fix old signs, and use digital tools for better evacuation. Government groups want everyone to follow rules and update signs for safer evacuation. Private companies spend money on new tech to make evacuation better. Smart buildings and quick alerts make evacuation more reliable. FAMA’s Smart Traffic Signal Control and Ground Luminous Sign Series give clear signals and help guide people during evacuation.
