WHAT DEFINES THEM?

REI120 and REI180 fire rated gates are available with horizontal sliding. The field of application includes the closure of large openings and/or special usage conditions in the dimensions requested by the customer. Gates are supplied with leaves made with flush panels of insulated sheet metal, top tubular tracks, protective carters, counterweights, thermal or electromagnetic fuses and finished with a base coat or RAL colors, plus other accessories required for the correct functioning of the product.

Standards

The gates are certified in accordance with the UNI 9723 standard in compliance with the ministerial provisions in effect.

Opening direction

The opening direction needs to be specified when the order is placed.

Two-leaved gates available in the following classes:

Sliding gates available in the following classes:

ATTENTION Fire compartmentalization elements should always be used properly. They are only designed for installation in spaces and constructions that are vertically aligned and flush. 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).

NOTE Fire rated gates require careful design which reflects their dimensions and special functions. Every installation site should be measured and checked for vertical alignment of the walls and gradients of the flooring. 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.

OPERATION MODE OF SLIDING FIRE GATES WITH ONE OR TWO LEAVES

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 thermal fuse is only triggered when the temperature in the immediate vicinity rises above 70° C, and it does not respond to smoke. Its application, therefore, is not advisable when the gates are located outside the compartmentalization space and when a reaction to cold smoke is required.

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.

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.

Group 03 (Basic anti-corrosion coating + satin topcoat finishing): *Pre-approval of the sample is required.

Group 04 (Basic anti-corrosion coating + satin topcoat finishing):

Group 05 (Basic anti-corrosion coating only):

Basic anti-corrosion coating is available for all colors listed in group 02. In general, all RAL tints are useable except for: RAL 1018, RAL 5005 and RAL 9007

NOTE 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 prod- uct degradation, such as:

  1. 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.
  2. 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:

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.


PEDESTRIAN DOOR

REI 120 sliding gates, with one or two leaves, may be equipped with a pedestrian door with or without a lower threshold. Pedestrian doors with thresholds and panic bars are not suitable for escape routes. The right or left opening direction should be specified by the customer during the ordering phase. By default pedestrian doors are inserted in the second panel, which is next to the panel with the handle. For additional information about the SLASH panic exit device, please see the dedicated pages in the panic exit device section of the present website.
