Smoke Detection in High Ceiling Applications Using ASD
As a result designers and installers tend to use detection technologies such as beam detection and aspirating smoke detection (ASD) where smoke measurements over an area, rather than from a single location, are determined. Independent tests have shown that ASD has a far higher sensitivity to smoke than point detector technology, resulting in a superior ability to detect smoke that is diluted or distributed as it rises to higher levels.
Using ASD for Coincidence & Redundancy Detection
Commonly known as “double knock”. Coincidence detection relies on alarm signals across two zones or between two detectors to activate before any evacuation/alarm occurs. In this instance, depending on the ASD specification, a detector or each pipe inlet can be used as a zone/address. Look at the table below to see which detectors can be used as a single zone or multiple zones/address.
Addressable Aspirating Smoke Detection for Data Centres
usually consist of a large group of computer servers networked together, their main purpose being to provide companies and organizations internationally with remote/cloud storage, processing and distribution of large amounts of data.
How the EF-ASD can be used to protect a lift shaft
With most modern buildings being multi-level, lifts (or elevators) are a critical part of a buildings operation, forming an essential part of a life safety strategy. It is vital that lifts and lift shafts are considered critical for fire protection and evacuation strategy and therefore it is vital that a lift and lift shaft are equipped with a suitable fire detection system.
