Many readers are already aware of the Yale 7000 series exit devices, but you probably are not aware of all of the options it offers, and most definitely you are not aware of the newest feature: photoluminescence.
Being able to quickly find the exit and get out of the building safely during an emergency can help avoid a tragedy and should be a main priority of any building's safety plan. During a true emergency situation, where smoke could hide lighted exit signs or when power might be interrupted to line powered EXIT signs, auxiliary non-powered emergency exit indicators might make the difference between safe egress and tragic loss of life.
This new technology by Yale enables the locksmith to offer building owners the opportunity to exceed the most current life safety codes regarding signage.
Photoluminescent (PL) technology is not new and it is probably one of the most widely used forms of egress marking; however in the past this technology was primarily deployed in military applications.
PL absorbs ambient lighting which is then emitted when the light source is diminished or eliminated. Photoluminescence produces a sustained visible glow in darkness, which provides sufficient illumination for exit from a darkened area. PL material is made from strontium aluminate - similar to, but much superior to zinc sulfide, the material use to make "glow-in-the-dark" toys. PL only requires exposure to an ambient light source for approximately 15 to 30 minutes to provide a visible glow for many hours in a blackout situation.
PL is applied to the exit device using powder coat technology. Powder coat technology is a very durable coating and is resistant to abuse and normal wear. Modern high-performance PL materials used indoors have almost no decay over a 15-year period and are virtually indestructible.
PL technology is available in green, red and blue colors. Yale has chosen the green PL finish as it is the brightest and longest lasting.
PL is ideal for use with any door in a means of egress. Stairwell doors, corridor doors, and other exit access doors are all candidates for the use of PL exit devices.
Adding the PL touchpad cover to Yale® UL listed fire-rated exit devices has been tested and found not to affect operation, nor does it alter the Listing for the device.
As the consequence of 911 and several other recent tragic events, the use of photoluminescent products has been mandated by a number of international, national and state authorities concerned with life safety.
ASSA ABLOY has responded by introducing Photoluminescence as part of its LiteGuide™ egress lighting system to enhance exit signage and provide visibility of exit doors in low-light, no light or smoky conditions.
New York City has made PL the only acceptable technology for a range of applications. It is mandatory that PL signage and markings are in stairwells of office buildings in excess of 75 feet in height. Office buildings must have PL signage and markings either installed or a permit for extension by July 1, 2006. The PL exit device touchpad cover will assist building owners in meeting these requirements.
LiteGuide PL Benefits:
- The photoluminescent material is powder-coated to the touchpad cover.
- Requires no wiring, no maintenance, and is unaffected by heat, cold and shock.
- Vandal resistant.
- Recharges from ambient light.
- Simple and economical to install in any building and especially suitable for existing buildings.
- Non-toxic, will not rub or fade.
- Fire-resistant and non-radioactive.
The touchpad cover can be ordered separately and easily retrofits to existing 7000 series exit devices in the field. Touchpad cover comes standard with the word "Exit" centered in 1.5" high lettering. If there is a requirement for the cover without the word 'EXIT', then this would be a special application request and may result in additional lead times (up to 10 weeks).
Yale has introduced photo luminescence for the 7000 Series Exit Devices.
