Using Wi-Fyre with an existing analogue addressable fire alarm system
Analogue addressable fire alarm systems differ from conventional fire alarm systems in many ways, principally by providing improved flexibility and control.
Linear Heat Detection from Eurofyre
Linear Heat Detection can offer early detection of fire or warn of over-heating equipment in a specific area. Linear heat detection uses lengths of sensing cable that work in a similar way to conventional heat detectors, the difference being that they are capable of detecting fire, or excessive heat, at any point along their length. There is no minimum length exposure required to generate an alarm signal and systems can be installed using lengths in excess of 1000m.
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.
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.
