Telescopic gates fire rated

Features

Classes:

  • REI 120 standard UNI 9723: with monolateral and bilateral opposing leaves

Installation

On weight-bearing masonry walls or ceilings.

Gates leaves

Two/four leaves made of continuous panels of hollow-core sheet metal insulated with appropriate materials. Assembly involves screwing the structure to pre-prepared horizontal profiles. Leaf thickness 80 mm.

Top guide track

For horizontal sliding, made of press-folded steel with predrilled holes for attachment using plugs (not included). Overhead sliding on low friction carriages. The extension of the floor-mounted guide track beyond the opening ensures the perpendicularity of the leaf. The top guide track is covered by a protection carter made of press-folded sheet metal.

Overlapping labyrinths

Made of press-folded steel.

Counterweight

For adjustable closure and protected by press-folded sheet metal carters, with counterstrike inset and shimming inset.

Door handles

Recessed on both sides of the first leaf or of the first two leaves.

Sealing

Thermo-expanding on all overlapping labyrinths and underneath the leaf.

Identification plate

Marking with reference information that is applied directly to the handle (one of the handles, in case of bilateral version).

Packaging

Modules on disposable metal container.

Operating mode

Of the gate series with thermal fuse: the gate can stand still at any position. The counterweight remains hooked to the thermal fuse and only closes the gate when the fuse fails.

Mandatory accessories

Pulley tackles for sel-closure

Pulley tackles serve to ensure the full self-closure of telescopic gates which are wider than they are tall.
Maximum width WITHOUT TACKLES: (H-800) x 2.

VT -VISCOTROLER® Accident prevention device

Gates should always be equipped with an automatic device that controls the feed speed of the door during automatic closing. After the critical moment when automated re-closure has been initiated, door speed increases progressively in proportion to opening time and door weight. During emergency situations, the energy that develops could cause serious injury/damage to people or objects within its range of motion. The hydraulic V.T. VISCOTROLLER® rotor makes it possible to set a constant closing speed in the range of 0,05 to 0,25 m/sec.

Feed-in impact absorber

Mandatory accessory for one- and two-leaved telescopic gates. The compression energy on the shaft is absorbed by slowing the flow of a fluid by means of an adjustable limiter valve. The shaft of the shock absorber is re-armed when the gates is re-opened.
