Type RM-O-3-D

For smoke detection in ducts

Duct smoke detector used to prevent smoke from spreading through the ducts of ventilation and air conditioning systems

  • To provide the control input signal for fire dampers
  • To provide the control input signal for smoke protection dampers
  • Can be installed into the inspection access openings of rectangular fire dampers
  • For airflow velocities up to 20 m/s
  • For any airflow direction
  • Contamination level indicator
  • Automatic adjustment of the alarm threshold, hence long service life and little requirement for maintenance
  • Volt-free signal and alarm relays


Optional equipment and accessories

  • Integration into the central BMS with TROXNETCOM
  • Voltage monitoring module (24 V DC)

Duct smoke detector RM-O-3-D 00136667_0
  • Application
  • Description

Application

  • Duct smoke detectors of Type RM-O-3-D are used to control fire dampers with electric or electric-pneumatic release mechanisms (power off to close)
  • Control of smoke protection dampers with electric spring return actuators
  • Used to prevent smoke from spreading through the ducts of ventilation and air conditioning systems
  • Integration into the central BMS with TROXNETCOM

Special characteristics

  • Smoke detection based on the principle of light scattering
  • For airflow velocities from 1 to 20 m/s
  • For any airflow direction
  • Can be fitted onto the FK-EU
  • With volt-free signal and alarm relays
  • Integral signal lamps
  • Contamination level indicator and automatic adjustment of the alarm threshold, hence long service life
  • Can be used with products of any make or model
  • Annual maintenance

Classification

  • Building inspectorate licence Z-78.6-67 from the DIBt, Berlin, Germany

Variants

  • Plastic casing

Standards and guidelines

  • Building inspectorate licence Z-78.6-125 from the DIBt, Berlin, Germany
  • Guideline regarding fire protection requirements on ventilation systems (Lüftungsanlagen-Richtlinie, LüAR)

Maintenance

  • The functional reliability of the duct smoke detector must be tested at least every 12 months; this has to be arranged by the owner of the ventilation system; functional tests must be carried out in compliance with the basic maintenance principles stated in EN 13306 and DIN 31051.
  • Duct smoke detectors must be included in the regular cleaning schedule of the ventilation system
  • For details on maintenance and inspection refer to the installation and operating manual
