Each United Steel Products fire door release device serves as an interface between the smoke detection system and the fire door. As the central access control, the fire door release system receives and interprets all signals to instruct the fire door and all warning devices to act appropriately.

United Steel Products offers a choice of three different models, for both motorized and non-motorized applications. For motorized applications, the appropriate release device works in conjunction with a standard, commercial electromechanical or solid-state operator to create an enhanced, yet economical, fire door operating system. All devices ensure the continued protection and code compliance for the fire door, rolling door, or shutter door by enabling routine operation inspections without activating the primary alarm system and without disturbing building occupants. All our fire door release devices are C-UL-US, FM, and CSFM listed and are compliant with the NFPA 80 requirement for a fail-safe door holder/release device.
