Low location lighting (LLL) emergency wayfinding systems - Safety Way Guidance Systems (SWGS)

Continuous markings of escape routes with indications of direction is of vital importance in order to evacuate all personnel from a hazardous zone (e.g. a fire aboard a ship, an airplane, nuclear installations, prisons and hotels, but also from private homes). Metal Safe Sign (MSS) offers complete low location lighting (LLL)-system solutions for both land and sea markets.

Did you know that the New York City Council states that all 75 (25m) high-rises got to have LLLL/SWGS? Read press release.

FAA in the US tested the use of phosphorescent markings on aircrafts (replacing electrical wayfinding systems. Strontium aluminate pigments were recommended used. The report from these test can be found in pdf-format here. We've also made available two articles for your reference:

Specially developed and maintenance-free aluminum profiles gives the photoluminescent plates a 17 degrees tilt out from the wall, enabling optimal usage of loading-light and providing the best field of vision for escapees. Refitting of existing LLL-systems is provided as one of our services. With high quality photoluminescent pigments like ours, the afterglow effect is so good that it is possible to reduce the required 75mm width on LLL (IMO Resolution 752(18)) to only 50 mm, thus making it attractive to naval architects and interior designers.

Test results

Test-results ISO 15370:2001 Annex A - 25 lux
Illumination for 24 hours. Complete darkness and reading after 10 and 60 minutes. Light-source is 25 lux. Ask competitors for their qualities in accordance with this standard.
Please note: Only 25 lux charging light, and not 1000 lux (DIN 67510) like so many other companies' use! MSS makes products for real-life applications - not laboratory tests.

25 lux - Real-life test After 10 minutes After 60 minutes
Measured results: 136 mcd/m2 42 mcd/m2

Test results DIN 67510:1992 - 1000 lux
This is the laboratory test that most suppliers of comparable products refers to. MSS samples were held in absolute darkness for at least 24 hours before the samples were exposed to 25 lux for 24 hours. The following measuring results were achieved:

1000 lux - laboratory After 10 minutes After 60 minutes
Measured results: 730,0 mcd/m2 100,0 mcd/m2
Requirements: 22,5 mcd/m2 3,0 mcd/m2

All our products have passed Fire Test Procedure Code - 2 and 5 necessary for wall and bulkhead mounting in escape routes in enclosed areas. When comparing measuring and test results from other suppliers, ALWAYS ask them what their tests are based on! Test results should reflect the actual conditions where the products are to be used, and not optimal laboratory conditions (contact us for more information).

Test results Measurement according to DIN 67510 Part 2 10x10 strip of LLL - 1000 lux

10x10 mm strip LLL - 1000 lux After 10 minutes After 60 minutes
Measured results: 743,0 mcd/m2 120,4 mcd/m2
Requirements: 22,5 mcd/m2 3,0 mcd/m2

Lowest visible threshold of 0.3 mcd/m2 reached after : 18030 minutes

Example of Ultra Brite quality - one of our older qualities

Our LLL-systems with the "Ultra Brite"-quality are produced with a photoluminescent layer of 300m on 0,68 mm white-enameled aluminum.
The photoluminescent effect is measured by DIN 67510 part 1 to:
170 mcd after 10 minutes and 27,8 mcd after 60 minutes product-quality.
