WHAT DEFINES THEM?
REI120 telescopic fire rated gates are available as horizontal sliding doors.
The field of use includes large openings and/or special usage conditions in customer-specified dimensions. Gates
are supplied with leaves made of flush insulated sheet metal panes, sliding guides, protective carters, counterweights,
thermal fuses or electromagnets and finished in a base coat or RAL colors, plus other accessories as required for correct product functioning.
Standards
The gates are certified in accordance with UNI 9723 standards in compliance with the current ministerial provisions
in force.
Opening direction
Opening direction needs to be indicated while placing the order.
Bilateral Telescopic Gates available in class:
Particular care must be taken to check for protrusions or blockages that might hinder the operation or free movement of the gates. Given the considerable weight of gates, the bearing capacity of the walls and crossbeams involved should be checked for the mounting of top guide tracks and overlapping labyrinths.
Compartmentalization for interiors is for areas that are not subject to strong air currents. Installation to be executed by specialized technicians only. For special applications consult with our technical office.
The holding system for the gate is chosen by the customer to conform with their own worksite needs and the anti-fire design (thermal fuse or electromagnet).
REI 120 MONOLATERAL VERSION WITH TWO LEAVES
In conformity with UNI 9723 for two leaves, the telescopic mono-lateral gates series has the following characteristics:
Installation
On weight-bearing masonry walls or ceilings.
Gate 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.
Sealing
Thermo-expanding on all overlapping labyrinths and underneath the leaf.
Identification plate
Marking with reference information that is applied directly to the handle.
Finishing

OPERATION MODE OF TELESCOPIC FIRE GATES
The selection of the holding system should reflect the customer’s worksite needs and the anti-fire project.
Operation mode of gates equipped with thermal fuse:
The counterweight (1) does not load the gate and the operator (2) manually opens and closes the gates, which remains in the position it is left in. When the thermal fuse (3) is subjected to temperatures greater than 70° C, it
breaks and causes the cable (4) to be released, so that the counterweight drags the gates to the closed position. The
feed speed brake (5) prevents the gates from accelerating during closure. The feed-in impact absorber (6) softens the final feed-in impact of the closure.
Operation mode of gates equipped with electromagnet:
The counterweight (1) continuously loads the gate. The gate usually remains open, held in place by the electromagnet
(2). The counterweight closes the gate whenever the electromagnet lacks impulse current from the control unit or when the release button (3) is pressed. The feed speed brake (4) prevents the gate from accelerating during closure. The feed-in impact absorber (5) softens the final feed-in impact of the closure. The electromagnet must be connected with a power control unit and the related external smoke and heat detectors.
NOTE: The gate closes on impulse from a control unit controlled by an external RFC detector, thus permitting automatic closure at temperatures lower than 70° C as well in the presence of cold smoke. This means that the gate can be installed in any position, even outside the compartmentalization space.INSTALLATION
PAINTING
With ecologically formulated anti-corrosive epoxide primer. Minimum resistance to salt fog exposure: 300 hours (A.S.T.M. B – 117 – 61). Basic anti-corrosion coating: Light turquoise pastel. Optional: finishing with satin topcoats
from the selection of furnace polymerized RAL colors.

Cleaning
Water and neutral soap are recommended for the regular cleaning of our products. Do not use common cleaning products (see detergents) and/or other solvents. We shall not be held responsible for any problems that arise if these
guidelines are not respected.
Re-painting
For re-painting, use the following procedure:
- sand and carefully wipe away any dust from the surfaces
- apply a base layer of opaque 2-component epoxide we recommend EPOX product Nr. 5203 beige 0059 made by ALCEA in Milan
- repaint the surfaces with your choice of lacquers or paints.
*Pre-approval of the sample is required.
In general, all RAL tints are useable except for: RAL 1018, RAL 5005 and RAL 9007NOTE: Due to artifacts of the printing process, the colors depicted here may not correspond exactly to the colors of actual doors. Please see the RAL or NCS samples.
Retouching
On request, Ninz also provides touch-up paint (nitro/synthetic) in 1,00 kg cans in the necessary RAL tint.
Protection
Since the gates are designed for internal usage, they should always be protected from atmospheric agents and direct sunlight.
Exterior uses require paints that are specially designed for this type of use (on request).
ATTENTION! External installation of gates require various measures for preventing product degradation, such as:
- The gates should always be protected from bad weather. Permanent damage may result if water seeps inside the door leaf. Provide canopies or roofi ng to protect newly installed and existing products.
- Avoid darker colors for gates which will be exposed to direct sunlight. Sheet metal can heat up and cause warping of the door leaf which could compromise the functionality of the door itself.
PULLEY TACKLES FOR SELF-CLOSURE
Pulley tackles serve to ensure the full self-closure of sliding gates which are wider than they are tall.
Maximum width WITHOUT TACKLES: (H-800) x 2
“Normal” pulley tackles
2 pulleys and standard counterweight box:
- for gates wider than (height H – 800) x 2 and shorter than (height H – 800) x 4
- minimum space required on rebate side 250 mm
- for geared counterweight: required space on the opening side L + 400 mm
“Special” pulley tackles
2 pulleys and augmented counterweight box:
- for gates wider than (height H – 800) x 4 and shorter than (height H – 1150) x 6
- minimum space required on rebate side 350 mm
- for geared counterweight: required space on the opening side L + 500 mm
“R” pulley tackles
3 pulleys and larger counterweight box:
- for gates wider than (height H – 1150) x 6 and shorter than L=7000 mm
- minimum space required on rebate side 350 mm
- for geared counterweight: required space on the opening side L + 500 mm
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.
ATTENTION! For purposes of accident prevention, gates should always be equipped with a feed-in brake to regulate closing speed. Customers who choose not to include the feed-in brake assume full responsibility for possible consequences.
FEED-IN IMPACT ABSORBER
Mandatory accessory for one- and two-leaved sliding gates. Compression energy on the shaft is absorbed by slowing the flow of a fluid by means of an adjustable limiter valve. The shock absorber of the shaft is re-armed when the gate is re-opened.
ATTENTION! Be careful not to damage the impact absorber shaft!ELECTROMAGNETS
Gates operation mode with electromagnets (on request): the gate is usually left open. The counterweight is always hooked to the leaf and closure occurs whenever the electric current to the electromagnet is interrupted.
For smoke/heat detection systems, control unit and power supply, see the dedicated page in the accessories doors section of the present website.
