Specifications
Underwriters Laboratories 3-Hour/Class ‘A’ Label or Oversize Certificate of Compliance is furnished standard. Designed to close automatically from a fully open position. Email us today for more information or a free fire door estimate.
Face of wall or between jamb
Push-up to 8′ wide and high and chain hoist on larger sizes is standard; awning crank, crank box or motor operation is optional
Thermally activated by 165 degrees fusible links, with the closing speed regulated by a governor device operative only during automatic closing
Interlocking slats are roll formed from galvanized steel coil. Gage of slats is as required by the listing. Endlocks are riveted to slats to maintain curtain alignment. Bottom of curtain is reinforced by a double steel angle foot piece.
Steel channels or structural steel angles from curtain guides are bolted to structural steel wall angles. Sizes of guides are as required by the listing.
Steel plate brackets are bolted to wall angles to support curtain and barrel and provide mounting for hood.
Formed from minimum 24 gage galvanized steel sheet, reinforced with top and bottom flanges to limit deflection. A thermally released integral flame baffle is provided when required by the listing.
Far far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated they live in Bookmarksgrove right at the coast
Slats and hoods are pre-finished with a baked on grey polyester primer before forming. Foot piece, guides and brackets receive one coat of rust inhibiting black primer.
Fail Safe Release Devices
(Standard feature on all Model SS90 release devices is an adjustable time delay of up to 30 seconds.)
Standard base model
Standard base model with additional relay contacts
Standard base model with additional relay contacts, and battery back-up for power lost
Standard base model with additional relay contacts, battery back-up for power lost, and additional logic board to electrically run fire door down thru a motor operator avoiding mechanical release
Can be added to any model, allows a standard audio warning or an optional warning tailored to your specific needs.
To support a motor operator during a power failure
Options:
Photoelectric (detects smoke and heat) or ionization (detects combustion); requires connection to a release device with compatible voltage.
Electro-thermal and McCabe links (normally open circuits); electro-magnetic and time delay failsafe releases (normally closed circuits).
Provides automatic closing and testing of motor operated fire doors upon activation by a detector or alarm; eliminates the need for mechanical release and reset unless there is power loss; allows for a cycling sequence of the door in the event an obstruction is encountered upon closing.
Viscous speed governor patented to allow for a smooth and quiet descent in place of the standard ductile iron governor.
Brush seals factory applied to guides and foot piece, field installed on header, to aid in smoke and draft control.
Single or multiple 4″ wide cut-outs, glazed with clear wire glass (1 1/2 hour rating)
On Foot Piece.
