In Part 2 of this article, the smoke detection performance of the particle-charging method is demonstrated. All three commonly used materials, including ABS, tinned copper and PVC, are subjected to the pyrolysis test presenting highly reliable detection performance for various…
Regulation changes for smoke and carbon monoxide alarms will ensure greater protection
On 23 November 2021 the government in England published the results of a consultation proposing an extension to regulations for smoke and carbon monoxide (CO) alarms, applicable to all rented properties within England. In this article, Aico’s National Technical Manager,…
Principle and application of aspirating smoke detectors (ASDs) with an innovative method for very early fire alarms – Part 1
From the earliest laser to particle-counting methods, air-sampling aspirating smoke detectors (ASDs) for very early fire warning has made an essential contribution to property protection. Part One of the article introduces the particle-charging method’s principles and evaluates the charging performance…
An innovative flame detector solution for helidecks and aircraft hangars
Applications that demand heightened immunity to false alarms include the use of helicopters offshore and aircraft hangars, both military and commercial. The Civil Aviation Authority publication CAP 437 ‘Standards for offshore helicopter landing areas’ has become an accepted worldwide source…
Performance-based smoke detection reduces cost and enhances safety
For special architectural features such as atria and large open spaces, advanced smoke detection technology minimizes costs and detects smoke at the earliest possible stage from flexibly placed, concealable sampling points. Today, the owners of a growing number of non-standard…
Flame detector selection Part 2 – design considerations
Part One of our flame detection guide provided some pointers for the selection of flame detectors based on the sensing technology employed. This second article sets out some design considerations for your flame detection system. Broadly speaking, these considerations fall…
Wireless detection
More than four years since the Grenfell tragedy, we are still very much in the midst of the ACM cladding fiasco. While the government has committed to spend £600 million on the replacement of unsafe cladding on both social housing…
Flame detector selection: Part 1 – detection technologies
This is the first of a two-part article where we provide pointers for flame detector selection, based on the detection technologies used and application. For decades, radiant energy-sensing flame detectors have been applied as optical fire detectors for industrial and…
Reliable fire and smoke detection in recycling facilities
Waste is per se something ‘dirty’; hence, the environmental conditions within recycling facilities are most challenging. In addition, the environment is highly dynamic, the level of dust changes very quickly when, for example, trucks are loaded or unloaded. Furthermore, fires…
Multi-sensor fire alarms: four things you may not know
Optical detectors may be the number one fire detector in the market today, but the popularity of Multi-Sensors has increased dramatically over recent years and prices have fallen, making them all the more attractive. Multi-Sensors combine two sensor types within…
Using flame detectors for Zone 2 Hazardous Areas
84In this article the fundamentals of Hazardous Areas are outlined and Flame Detector applications, split into Zone 1, Zone 2 and Safe Areas are discussed. This is not a definitive explanation of Flame Detector types or how they work, but…
What can a two-wire system offer you that conventional can’t?
AlarmSense is a range of conventional two-wire detection and alarm devices that connect to the same pair of supply wires. This design saves time on installation and, alongside the ability to priority switch sounders, makes AlarmSense an incredibly flexible system…
Flame detection through the use of 3D mapping to aircraft hangars – Part 2
In the previous edition of International Fire Protection, we discussed the challenges posed by aircraft hangars in relationship to flame detector selection. In this edition William Pittman discusses how 3D flame detector modelling techniques can be used, in combination with…
Flame detection through the use of 3D mapping to aircraft hangars
In this first, of a two-part article, William Pittman, PhD discusses the challenges posed by aircraft hangars in relationship to flame detector selection. In the next edition of Gulf Fire William discusses how 3D flame detector modelling techniques can be…
Flame detector selection – Which one?
Which flame detector should I use? This is a common question when a fire protection engineer is looking to protect a high value asset or where fast detection is needed due to the escalation potential of a fire. So, where…
