Sliding fire doors are the ideal solution for protecting large openings, such as industrial access points, multi-storey car parks, warehouses and shopping centres, where a high level of compartmentalisation is required, combined with highly reliable closing systems. In this field, Sisti Engineering – the first company in Italy to have fire doors of its own design tested by the Ministry of the Interior – offers a range of high-quality solutions, developed to ensure superior performance.
When sliding fire doors are required
Sliding fire doors are used when a fire escape route cannot be accommodated by hinged doors, either due to space constraints or specific operational requirements. The main areas of application include:
In these applications, the size and weight of the door leaves make the mechanical design a crucial factor. The smoothness, reliability and repeatability of the closing movement in the event of an emergency must be guaranteed over time, without compromise. For this reason, every door undergoes particularly rigorous testing procedures, which exceed the standards required for regulatory approval alone.
Every Sisti Engineering sliding fire door can be fitted with a complete control and automation system, designed to integrate effectively with the building’s fire protection system. The configuration may include:
- 24V DC solenoids (1.5W) with backing plate and manual release button;
- EN 54-2 / EN 54-4-certified single-zone control unit, capable of managing up to 4 solenoids and 5 smoke or heat detectors, with integrated 12V backup battery;
- EN 54-5 / EN 54-7-certified smoke and heat detectors;
- EN 54-3-certified electronic siren and EN 54-11-compliant alarm activation button;
- Hydraulic end-of-travel damper with magnetic head and closing speed regulator;
- Customised motors, fitted with safety devices compliant with current regulations;
- Customisable surface finishes, available in the RAL colour range or with special-effect coatings.
An integrated system that combines safety, control and adaptability to specific design requirements.
Every Sisti Engineering sliding fire door is the result of a design approach focused on quality and reliability, which is reflected in the mechanical design, functional performance, aesthetic finish and selection of fittings. The entire production process is supported by a management system certified to ISO 9001 since 2004 (certificate no. SQ041804), ensuring rigorous and traceable control at every stage, from design to delivery.
