RECENT HAPPENINGS IN THE MARKET
- Underwriters Research labs announced its two new smoke alarm and sensors standards in February 2018. The seventh edition of this norm is slated to take effect in May 2020. It focuses on reducing false alarms, often understood as nuisance alarms, and on identifying specific smoke characteristics. New smoke sensors may, therefore, be able to distinguish between toxic smoke from cooking. Essentially, the smoke from non-lethal sources and actual life-threatening smoke.
