    2. Door Panels: Each assembly to consist of continuous length, 4 ½" wide panels formed of 24 gauge commercial grade coated steel, corrugated for strength and resilience.
    3. Hinges: Continuous length, full height 24 gauge commercial grade coated steel hinges interconnect door panels.
    4. Upright Lead Post: Formed of 24 gauge commercial grade coated steel with finish to match door panels. Connect to door panels with specially formed sections. An internally mounted plumb bar support shall keep the lead posts vertical and in proper alignment during operation and insure tight fitting closure of the door.
    5. Wall Mounted Striker Post: Recessed 18 gauge coated cold rolled steel member that receives the lead post and is secured to the wall opposite the stacked door.
    6. Floating Jamb: 18 gauge aluminized steel floating jamb assembly that travels within the storage pocket and forms a seal at the pocket end of the door.
    7. Fully assembled and extended unit hanging weight shall be approximately 5.5 pounds per square foot.

B. Suspension System

ALUMINUM TRACK IS AVAILABLE FOR STRAIGHT SLIDING UNITS TO 1 1/2 HOUR MAXIMUM RATING. SELECT FORMED STEEL TRACK WHEN DESIRED, WHEN REQUIRED BY LOCAL CODES AND WHEN CURVED TRACK OR A 3 HOUR RATING IS REQUIRED. A MINIMUM 5' RADIUS IS REQUIRED FOR ALL CURVED SECTIONS.

    1. Track: Interconnected double rail [heavy duty extruded aluminum] [formed steel] track sections on 8" centers for attachment to overhead structural support system. Shape is designed for smooth running operation of the roller assemblies while prohibiting any opportunity for the rollers to derail.
    2. Rollers: Each lead post/plumb bar assembly shall be suspended by a 12 wheel ball bearing trolley system. Each individual panel shall be suspended using a steel hanger pin and ball bearing roller.

C. Perimeter Seals: Continuous extruded fire-rated sweeps and a fire liner attached to the top and bottom of the fire door form a smoke and draft seal.

D. Finishes

  1. Door panels, hinges and upright posts: Coating process to include a flexible urethane primer followed by a high performance, medium gloss, baked-on polyester coating [in manufacturer's standard Platinum Gray color.] [. Color shall be selected from manufacturer available optional colors at additional cost and additional production lead-time.]
  2. Track: to be supplied [with a white baked-on powder coat finish.] [mill finish aluminum.] [with a color as selected from manufacturer available color options at an additional cost and additional production lead-time.]
  3. Perimeter Seals: Flat black.

2.3 OPTIONS

THE FOLLOWING CONSTRUCTION FEATURE IS REQUIRED TO SATISFY UL 1784 TESTING WITHOUT AN ARTIFICIAL BOTTOM SEAL. NOT AVAILABLE FOR UNITS WITH CURVED TRACK. COORDINATE WITH SECTION 1.2-A2b. DELETE SECTION 2.3 OPTION "A" FOR CURVED TRACK UNITS OR IF NOT REQUIRED OR DESIRED.

A. Non-Sway Construction Feature: Provide Fire Door with non-sway construction to limit the amount of curtain deflection due to notable air pressure differential on either side of the Fire Door opening.

2.4 OPERATION

A. Motor Operator Assembly: Shall consist of DC gear-motor, limit switch control system, drive sprocket and clutch. The motor shall drive the fire door by means of a chain attached to the plumb bar trolley system. Motor operator assembly shall be located within a fire rated enclosure equal to the wall assembly rating. Motors shall be operated by DC power supplied from two (2) 12-volt maintenance-free batteries located in an electronic control box. Batteries shall be continuously charged by the building's electrical service and be automatically maintained at capacity. Fire doors may be operated manually in either the conventional or emergency mode. Electronic control box shall house the control panel, two (2) 12-volt maintenance-free batteries, power supply charger, and motor control relays. Control system is capable of remote status monitoring and remote operation. The control panel shall initiate a warning signal should any of the following conditions occur:

  • Loss of AC power.
  • Low DC battery power.
  • Overload condition.
  • High limit temperature switch activation or malfunction.
 
  1. Control Station: Flush mounted, "Open/Close" key switch with "Stop" push button; NEMA 1B.

OR

  1. Control Station: Surface mounted, "Open/Close/Stop" push buttons; NEMA

OR

  1. Control Station: Surface mounted, "Open/Close" key switch with "Stop" push button; NEMA 3R.

B. Leading Sensing Edge: Fire doors shall be equipped with a pressure sensitive, vertical leading edge such that each contact with an obstruction shall cause the door to stop and pause before attempting to re-close. Fire doors can be manually opened by pushing against the leading edge.

C. Emergency Exit Hardware: Shall be located on both sides of the fire door near the leading member. Slight pressure on the hardware will cause the door to open approximately 60", pause for three seconds, then automatically close. The system shall be field programmable to allow automatic opening distances up to the entire opening width. The hardware can be used to open the door and move it back into the storage area during non alarm operation of door.

D. Security Control: When activated, the Emergency Exit Hardware shall not respond when pressed unless there is an active emergency signal from the smoke or fire alarm system. The motor operator assembly will provide greater than 250 pounds of resistance to manual forced opening. (Note: At least one key switch will be required to utilize this feature.)

E. Automatic Closing System: Shall consist of an electronic control box, motor operator assembly and leading sensing edge. Closing system shall be activated by the building's fire/smoke detection equipment and automatically close the fire doors. For additional protection, if the door is in the closed position and the temperature reaches 450° F on either side of the opening, door mounted high limit sensors will prevent Emergency Exit Hardware opening activation.
