The GT System 600 automatic fire door package provides a UL-listed system for fire door control when used with UL-listed doors, frames, hardware and sensing devices.

The System 600 can be surface applied to either single or double door systems and offers both automatic and manual operation. In the automatic mode, the system operates under a power-open, spring-close basis with adjustable open-close speeds. The manual mode provides easy operation in the event of a power failure, requiring less than 15 pounds of pressure to activate the system.
