Additional Information about Raynor Fire Shield Release Mechanisms
All Raynor Fire Shield release mechanisms are comprised of two components: A spring return motor and a control panel.
1. The spring motor has an adjustable arm connecting the fusible link cable to the door. During testing, the arm moves in an arc to release enough cable to allow the fire door to drop without disconnecting the fusible link.2. The control panel operates on 120 VAC and interfaces with the spring motor. It has a three position keyswitch (neutral, test, and reset) that prevents
unauthorized release of the door. Smoke or heat detectors or central alarm systems may be wired into the control panel.
One Fire Shield model is available:
Fire Shield I, with "Ready" and "Released" indicator lights on control panel.Additional Information about Raynor SS90 Release Devices
