M100 FireGard™ System

A fire door / motor operator system where the motor operator is utilized to control normal and automatic fire door closing. This system never requires mechanical resetting and average automatic closing speed is controlled not to exceed 9" per second, even on large units.

KuxePe1

FireGard™ EZ Test'n Set

Adds the ease of testing / resetting and controlling speed to manual chain operated fire doors. Each door is provided with a pad-lockable guide mounted test handle. This system is economically ideal for exposed fire doors that do not require the convenience of motor operation.

TYmC6h4

M60 FireGard™ System

This system adds control wiring to a conventional motor operator to close a fire door electrically in response to an alarm signal thus eliminating mechanical resetting due to frequent alarm testing. A release device is required with this system to close the fire door mechanically in the event of a prolonged power failure, which then requires mechanical resetting. This system is suitable for areas that have back-up power systems.

Brackets

Minimum 1/4" painted steel plates that bold to the guide assemblies and support the counter balance shaft and curtain.

Standard Material & Finish: steel, shop painted gray

Counter-balance Shaft

4-12" minimum diameter outer shaft. This assembly supports the curtain and contains counter-balance torsion springs for assisting operation.

Standard Material: steel

Hood

Protective sheet metal enclosure for the curtain that provides fire resistance at the head of the door and keeps the brackets rigid.

Standard Material & Finish: G90 galvanized steel with baked-on light gray polyester enamel.

Optional Material - stainless steel

Guides

Minimum 3/16" angle assemblies bolt to the wall and support the entire weight of the door.

Standard Material & Finish: steel with SpectraShield® powder coating 30-7192 gray.

Optional Material: stainless steel.

Bottom Bar

Two 2' x 2" x 1/8" back to back structural steel angles. Lock mechanisms available.

Standard Material & Finish: steel with SpectraSheild® powder coating 30-7192 gray.

Optional Material: stainless steel

Curtain

Interlocking roll formed slats with metal endlocks riveted to ends of alternate slats to maintain curtain alignment and prevent wear.

Standard Material & Finish: G90 galvanized steel with baked-on light gray polyester enamel.

Optional Material: stainless steel

Operation

Push-up operation, hand chain, hand crank and motors are available. Doors operate by rotating shaft gear end. The opposite end of the shaft applies spring tension and is equipped with a spring adjusting wheel.

  • Release Devices - are electro-mechanical devices that initiate automatic closing in response to an alarm signal. Fail-safe models are initiate closing following a ten second +/- power outage. Battery back-up devices are fail-safe, but can last up to 72 hours without initiating a release due to a power failure.
  • Annunciators - provide visual and audible advanced warning that a fire door is about to close. They are activated automatically upon an alarm signal or loss of power.
  • Vision Windows - enhance life safety and convenience by allowing visibility to the other side of the firewall opening. Up to six 10" x 1 5/8" non-wired glass panes are available per fire door curtain.
  • Perimeter Seals - UL listed perimeter seals applied to fire doors adds protection against the passage of smoke and drafts around fire doors.
  • G90 galvanized steel with backed-on tan polyester enamel
  • Stainless steel, 300 series #4 finish
  • Hot-dip galvanizing on steel components
  • Powder coat finish in selected color
