  • Application
  • Description

Application

  • Smoke protection dampers of Type JZ-RS are used in ventilation plant rooms or in ducts to prevent smoke from spreading (according to the German guideline regarding fire protection requirements on ventilation systems, LüAR)
  • For the refurbishment of systems with regard to fire safety
  • Can be triggered by duct smoke detectors with general building inspectorate licence
  • Integration into the central BMS with TROXNETCOM

Special characteristics

  • Low differential pressure and sound power level
  • Aerofoil blades
  • Low-maintenance, robust construction
  • No parts with silicone
  • Available in standard sizes and many intermediate sizes
  • Closed cell side seals meet increased hygiene requirements

Classification

  • Building inspectorate licence Z-78.4-51 from the DIBt, Berlin, Germany
  • Casing air leakage to EN 1751, class C
  • Closed blade air leakage at a differential pressure of 40 Pa = 200 m³/h per m²
  • Long-term testing: 10,000 open/close cycles

Nominal sizes

  • Standard: B = 400 – 2000 mm (in increments of 200 mm), H = 345 – 1995 mm (in increments of 165 mm)

  • Blade shafts, drive arm and external linkage made of galvanised steel
  • Side seal made of stainless steel
  • Brass bearings

Standards and guidelines

  • German 'Bau- und Prüfgrundsätze' [Principles of Construction and Testing], 2/84 edition
  • Maintenance standards DIN 31051 and EN 13305

Maintenance

  • Smoke protection dampers and duct smoke detectors must be maintained regularly and must be operational at all times
  • To maintain the normal function of the unit, or to re-instate its normal function, maintenance standards DIN 31051 and EN 13305 must be complied with
  • Smoke protection dampers must be maintained at least every 12 months
  • A maintenance report must be created; documents must be kept for reference
  • Maintenance-free as construction and materials are not subject to wear
