Tyco Fire & Building Products has announced its latest added protection device for glass bulb sprinklers, a plastic strap that wraps around the sprinkler and is part of the standard packaging from the factory. The device is designed for early removal after installation and contains a small 'see-through' slot that allows the installer to verify the glass bulb operating temperature by affording a view of the bulb and the color of the liquid inside. The device must be removed after the sprinkler has been installed.Tyco Fire & Building Products. www.tycoflow.com
