Automatic Maintenance for Aspirating Smoke Detection
Aspirating smoke detection is generally considered to be a low maintenance system in applications where there is minimal dust and dirt pollution such as an office, but what about applications such as, steel work factories, livestock facilities and mines?
Understanding EN 54-20 Aspirating Smoke Detection Sensitivity Classes
EN 54-20 specifies 3 classes of sensitivity to help with the vast amount of applications aspirating smoke detection can be used for. This is to ensure that the most appropriate sensitivity aspirating smoke detector will be selected for the proposed application/area.
Useful Aspirating Smoke Detection Accessories
The disadvantage of installing a large-bore aspirating smoke detection pipe run is the lack of flexibility in the direction. Changing the direction of a pipe run is generally done so by using either a 90 degree sweeping bend or a 45 degree bend. Flexible connectors on the other hand have the benefit of being positioned in any direction with no restriction to the air flow. They can also be useful when getting over obstacles such as a steel beam. Eurofyre are the suppliers for the following:
Aspirating Smoke Detection in Cold Stores
Cold storage areas that are typically used to store food that is either frozen (sub-zero) or chilled are considered to be high risk when it comes to fire protection measures. The combustible nature of materials stored within refrigerated environments, combined with the very dry high-airflow, creates a significant fire risk. A fire will spread rapidly between highly packed combustible materials such as cardboard and plastic packaging, grease impregnated materials, foodstuffs and wooden pallets, therefore, the earlier a fire can be detected the better.
Key Differences Between an ASD & LASD
The ASD transforms traditional ‘point’ detectors into powerful aspirating systems for use in normal, harsh, dusty, wet or inaccessible spaces. The ASD can house a variety of manufacturer’s conventional or analogue addressable point (spot) detectors and is available in either a single or dual pipe configuration.
