Johnson Controls to Debut New UL 268-Compliant Smoke Detection Sensors
The new UL 268 7th edition-compliant TrueAlarm sensors will be available for both the Simplex and Autocall product families in the spring of this year.
Johnson Controls, a technology company, is slated to release advanced smoke sensors that meet the latest updates to UL 268, which calls for significant improvements to smoke-detection technology.
Scheduled 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.
Johnson Controls’ new UL 268 7th edition-compliant TrueAlarm sensors will be available for both the Simplex and Autocall product families in the spring of this year, an announcement states.
The UL 7th edition polyurethane tests better represent the type of smoke and flames produced in modern building fires due to the increased use of synthetic furnishing materials that can ignite and burn faster than other materials. The cooking test was added after research showed people frequently disable smoke alarms due to nuisance alarms caused by cooking and shower steam.
The new TrueAlarm sensors provide earlier detection, better fire type recognition and fewer nuisance alarms, the announcement states. The devices are said to 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, multistage 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 design of our new sensors is based on decades of fire detection experience and demonstrates our commitment to creating the most innovative and reliable products in the industry,” says Wayne Aho, senior product manager, sensors, Johnson Controls. “These re-designed smoke sensors reduce the number of nuisance alarms while providing early notification, when needed, to help building occupants evacuate quickly and safely during a fire event.”
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 alarm, the company says.
