The latest updates to UL 268, Standard for Safety of Smoke Detectors for Fire Alarm Systems, call for significant improvements to smoke detection technology. Set to take effect in June 2021, the new UL 268 7th edition standard requires smoke sensors, detectors and smoke alarms to pass more than 215 new or revised performance tests, including three new challenging tests: a cooking nuisance alarm test, a flaming polyurethane foam test and a smoldering polyurethane test.

To satisfy these requirements, Johnson Controls has introduced advanced smoke sensors built upon its existing TrueAlarm technology.

The new TrueAlarm sensors provide earlier detection, better fire type recognition and fewer nuisance alarms. They use sophisticated algorithms to analyze particles and determine whether they are generated by an actual fire rather than smoke or steam from cooking. Sensor alarm points can be programmed for timed, multi-stage operation per sensor. A lower percentage alert can cause a warning prompt to investigate the issue while a higher programmed percentage will initiate an alarm.

The ability of the redesigned TrueAlarm sensors to intelligently differentiate between high-risk fires and burning food or steam is especially important for commercial spaces such as hotels, dormitories, hospitals and other facilities that are prone to nuisance alarms.
