RM-O-VS-D

Application

• Duct smoke detectors of Type RM-O-VS-D are used to control fire dampers and smoke protection 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
• Airflow monitoring
• With volt-free signal and alarm relays
• Integral signal lamps
• Choice of four airflow directions (every 90°)
• Easily removable sensor head (simplifies functional testing)
• Contamination level indicator and automatic adjustment of the alarm threshold, hence long service life
• Airflow monitoring unit (warning threshold < 2 m/s)
• Annual maintenance
• Can be used with products of any make or model

Classification

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

Standards and guidelines

• Building inspectorate licence Z-78.6-67 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
