The ASD 535 aspirating smoke detector consists of one or two independent sampling pipes, each having one or more sampling apertures and a sampling chamber. The air of the space being monitored is sucked in for precise analysis by the scattered-light smoke detector located in the sampling chamber. If it detects smoke particles beyond a preset threshold, it triggers an immediate alarm, allowing the fire brigade to deal with the fire before it has time to break out.
The ASD 535 incorporates the most powerful fan on the market, which means that larger areas than ever can now be monitored. Moreover, the new HD (High Dynamic) technology with which the smoke sensor is equipped represents a step change in detection accuracy. Its alarm sensitivity can be fine-tuned to the specific circumstances and hazard potential of the area being monitored. During commissioning, the auto-learning function adapts the system to the ambient conditions, and because impurities such as dust are efficiently filtered out, false alarms are a thing of the past.
The ASD 535 is ultra-sensitive, quiet and unobtrusive – qualities that make it perfect for a wide variety of applications:
Space monitoring: high-rack warehouses and distribution centres, archive rooms, intermediate ceilings and raised floors, large halls, museums, galleries, theatres, cinemas, cultural artefact collections, historical buildings, airports, information technology and computer centres, telecommunication centres, laboratory and research centres, electronic measuring rooms, transformer rooms, clean rooms
Property monitoring: telecommunication facilities, high and low voltage distribution cabinets, display cases, IT installations, electricity distribution cabinets, CNC control systems
Concealed applications: protection of cultural assets, prison cells, aesthetically sensitive architecture
