Auto-Test Tube Motor Operation
A solution for strict dimensional limitations around the header or where aesthetics are required, Cookson’s Auto-Test Tube Motor Operated Counter Fire Door’s motor is located within the shaft assembly to neatly conceal the operator and drive components. Upon activation, it will close without losing spring tension or disengaging the operator drive mechanism, providing simple testing and resetting of the closing system.
Auto-Test Chain, Crank, and Motor Operation
Provides a controlled rate of descent not to exceed 12″ per second upon activation of the buildings’ fire alarm system or local detector. Ideal for applications requiring frequent testing or when it is difficult to access the operating mechanism, these doors will not release spring tension and can be tested frequently from floor level by facility personnel.
Simple-Test Chain, Crank, and Motor Operation
These counter fire doors are better suited when connection to an alarm system or local detector is not required. These fuselink activated doors do not release spring tension upon activation. Chain and crank applications are ideal when power is not available at the opening.
The same fire protection you would expect from a Cookson Fire Door in a compact, push-up operated, counter door design. Fuselink activation initiates controlled doorclosure by releasing spring tension.
