JZ-RS

To prevent the spreading of smoke

Smoke protection dampers are used in ventilation plant rooms or in ducts to prevent smoke from spreading

  • Casing air leakage to EN 1751, class C
  • Low differential pressure and sound power level
  • Airflow direction is not critical
  • Available in standard sizes and many intermediate sizes


Optional equipment and accessories

  • Duct smoke detector RM-O-VS-D or RM-O-3-D
  • Installation subframe
  • Integration into the central BMS with TROXNETCOM

Application

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)

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

Functional description

Smoke protection dampers with external linkage have opposed action blades.

An external linkage transfers the synchronous rotational movement from the drive arm to the individual blades.

Even large dampers can be safely opened and closed with this type of linkage.

Opposed action blades close at different speeds since the linkage includes a transverse link.

This facilitates the closing process and reduces the closed blade air leakage.
