Johnson Controls said its components of the Metasys building management system meet Underwriters Laboratories (UL) revised standard for Smoke Control Systems and Equipment, UL 864 UUKL 9thedition.

The new standard requires faster response in an emergency. It aligns the UL standard with the National Fire Protection Standard 92A for Smoke Control.

When configured to integrate with a smoke control system, Metasys reacts to a fire emergency by adjusting air pressure in smoke-filled areas according to local codes and jurisdictions. It exhausts air from smoke zones to clear evacuation routes.
