ULTRA-RF/A ARCHITECTURAL SPECIFICATIONS

1.1       Door Leaf: The door consists of a solid core and laminated leaf. The sides and top of the door leaf are banded with a brass contact channel which is electro-mechanically bonded to the shielding media that is applied to the door face. A brass contact angle is mechanically attached at the bottom of the door. The standard door face finish is primed gray. As a option, the faces of the door can be supplied with a wood veneer or a high pressure plastic laminate (HPPL) which is "Natural Oak" in color. (Other colors and or finishes are available on request)

1.2       Door Frame: The door frame consists of a RF interface frame which the door jambs, sill and head are attached to. The jambs, head and sill are 12 gauge galvanized steel. The door leaf and door frame are furnished as a complete assembly and are available in a ADA flush sill or raised sill configuration.

1.3      Hardware: The ULTRA-RF/A is supplied with all hardware in a US26D finish and Clear Anodized (which is Satin Chrome). The hinge mechanism is a commercial grade, full surface, security hinge. The hinge system is designed and installed so there is no contact between the RF seals and the hinge plates. The standard lockset provided is a passage, extra heavy duty lever handle which meets the Accessibility Guidelines of the Americans With Disabilities ACT (ADA), the Uniform Federal Accessibility Standards and ANSI 156.2, Series 4000, Grade 1. Entrance, classroom, storeroom, privacy locksets and push/pull plate assemblies are available on request.

1.4       Threshold: The ULTRA-RF/A is supplied with a steel or stainless steel threshold for both the flush sill and raised sill configuration. The threshold is electro-mechanically attached to the door frame assembly. The threshold is available in single or dual tapers (for new or existing construction). The sill has a maximum height of 1/2" (after installation of customer supplied flooring).

1.5       Standard Door Size: The ULTRA-RF/A is supplied as a single leaf 3'-0" X 7'-0" standard which provides a clear finished opening of 2'-11" X 6'-11". The ULTRA-RF/A is available in other single or double door sizes on request.

1.6       Operating Force: The ULTRA-RF/A is designed to be opened or closed with less than 20 pounds of push or pull pressure.

1.7       RF Contacts: The ULTRA-RF/A is furnished with a single row of low pressure tin plated beryllium copper electrical contact strips. The contacts are installed on the door frame jambs and head section for a flush appearance. The contracts located at the bottom of the door are attached to a removable brass mounting angle. The contacts are designed and installed to be virtually maintenance free (since no lubrication of the door is required and they are protected by the door stops). Maintenance and or repairs can be performed at the user level. All repairs and maintenance can be accomplished with a Phillips head screwdriver, utility knife and scissors. The ULTRA-RF/A is also available in a high performance version which utilizes two (2) sets of electrical contacts. For further information on this high performance version or USER upgrade of an installed ULTRA-RF/A, contact us for details.
