- >UL 268 7th Edition Smoke Detector Standard
Hochiki is committed to and currently working with UL on a series of detectors (Analog & Conventional) which will be listed to 268 7th Edition.
Hochiki has already developed the technology to qualify and multiple tests in UL's new state of the art fire test laboratory have confirmed our capabilities.
A new 7th edition standard for smoke detectors will go into effect at the end of May 2020.
The changes in this edition standard are major in scope, most notably the addition of three new fire tests:
• Detection of flaming polyurethane foam
• Detection of smoldering polyurethane foam
• Reduction of nuisance alarms
In addition to the fire tests, there are over 250 other changes to the current standard. Our fundamental research has
determined that a new generation of detector is essential to achieve compliance.
Hochiki has concluded that single-sensor technology used today will not be able to comply with the new standards.
Substantial changes have been engineered to the detector construction both inside and out. These changes include air flow,
smoke chamber size and shape, sensing technology, and firmware algorithm updates.
Hochiki is committed to having our new generation of detectors (both analog and conventional) available before the May 2020
deadline. Hochiki will be announcing 5 new detectors and a beam detector. As a result, the first offerings which comply with
the new standard are expected in Q4 of 2019, and the FireNET L@titude will support them immediately.
