Do photoluminescent exit signs work?

Yes. Safety Path Exit Signs meet the performance requirements of the National Construction Code (incorporating the Building Code of Australia), ensuring that people will find fire exits even if the electricity has failed. Photoluminescent Exit Sign technology is a global building safety movement, with the signs in use in Europe, North America and South-East Asia.

Are photoluminescent exit signs legal?

Photoluminescent Exit Signs are permitted by the National Construction Code (NCC2019), which incorporated the Building Code of Australia. Safety Path Exit Signs meet the performance requirements of the Code (NCC2019 Specification E4.8).

How long do photoluminescent exit signs glow for?

Specification E4.8 in the National Construction Code 2019 requires that in the event of a power failure, a photoluminescent exit sign must continue to provide a minimum luminance of 30 mcd/m2 for not less than 90 minutes. Correctly installed Safety Path Exit Signs meet this requirement.

Photoluminescent exit signs vs electric-battery exit signs

Photoluminescent exit signs are replacing legacy electric-battery exit sign technology. Advantages of photoluminescent exit signs include the signs not consuming electricity, having no emissions, lower compliance costs, being more reliable, having a much longer life, and not producing toxic eWaste that requires special recycling schemes. New, upgraded and refurbished buildings can be easily designed to incorporate photoluminescent exit sign technology.

LED Hybrid Exit Signs can be used to directly replace legacy electric-battery exit signs by any competent electrician, in buildings across Australia. They incorporate a high-efficiency LED to charge the photoluminescent material with the sign. There’s no electric-battery, eliminating the high-risk of battery failure, reduced e-Waste and greater reliability – improving safety. Simply direct your electrician to replace any failed exit sign with its equivalent Safety Path LED hybrid exit sign.

Are photoluminescent exit signs radioactive?

The process of photoluminescence does not involve harmful radiation. Photoluminescence occurs when a type of molecule absorbs a light particle that is called a photon. This excites electrons in the molecule to a higher energised state. As the electrons slowly return to their normal state they emit photons of energy as visible light over a long period of time. This is how a photoluminescent exit sign can be seen in the dark – it is emitting stored energy as light.

How much light is required to charge a photoluminescent exit sign?

The National Construction Code (NCC 2019) requires 100 lux of light on the face of a photoluminescent exit sign. In a typical room light levels will exceed this requirement, but it must be measured to ensure it meets Building Code requirements.

Where 100 lux can’t be achieved, for example in a room with energy saving light sensors and other low-light environments like service corridors and plant rooms, Safety Path LED Hybrid Exit Signs are used. They have an efficient in-built LED to provide the 100 lux of light, but use reliable photoluminescent Smarterlite Technology instead of a short-lived electric battery. With simpler electrical components and no electric battery, Safety Path hybrid photoluminescent LED exit signs are more reliable than legacy electric-battery exit signs. In fact, Safety Path Hybrid Exit Signs can be used as a direct replacement for failed electric-battery exit signs.

Can I connect a photoluminescent exit sign to a building management system?

Photoluminescent exit signs have no electrical components to fail. Building management systems are designed to automatically report failed building assets to the building manager. With legacy electric-battery signs being prone to electrical and battery failures, building managers track their failures so that they are notified and can send an electrician to replace the whole unit.

By using photoluminescent exit signs, there’s no electric components to fail and no need for expensive networked exit signs and software costs to track their failures. Even more savings for the building manager!
