Early Warning Smoke Detection
Emerald Fire Technology is a fully accredited channel partner of Xtralis with many years experience in Design, Installation and Maintenance of VESDA systems
The workhorse of the Vesda range is the Vesda Laserplus (VLP) which can have up to 200m of sampling pipe with up to 30 sampling holes. The VLP has modular Programmer or Display options or can come with blank covers and non-latching relays for integration into addressable systems. The LaserScanner (VLS) is similar to the VLP but can monitor 4 pipes individually.
The LaserCompact (VLC) is a smaller unit which can have 50m of pipe. For even smaller applications the LaserFocus (VLF) can protect individual pieces of equipment, intakes to recirculating air-handlers or small rooms. There is even a tiny system the LaserQuantum (VLQ) designed for remote equipment cabins
The VLI is the new Industrial detector. Designed specifically to be rugged and dependable in harsh environments it has an IP66 housing, two filters and modular field-replaceable parts. With up to 360m of pipe it can protect up to 2,000sqm. There is a range of connectability options. The Vesda System Configurator software allows you to monitor background levels on a trend graph and set alarm thresholds accordingly.
The IAS (known as the ICAM IAS) is a low-cost simple aspirating device from Xtralis which allows standard addressable sensors to be installed in a fanbox. Ideal for protecting inaccessible spaces like ceilimng voids, ESB rooms, lift shafts or atriums, and when combined with a Notifier VIEW Detector it can give Class A early-warning protection.
The ECO is a revolutionary approach to gas detection. It effectively piggy-backs on a VESDA smoke detecion system and samples the air in the sampling pipe for the target gas. There are a range of gas sensor cartridges available for the ECO, both flammable and toxic. As with all VESDA equipment the thresholds can be set to match the environment.
The new VESDA E range is a quantum leap forward in aspirating detection, having a sensitivity range up to 15 times more sensitive than the Laserplus, and capabable of handling 800m of pipe and 80 sampling points. It has Wifi and Ethernet capablilty as well as the usual VESDA networking options.The layout is the same as the LaserPlus allowing it to be a 'drop-in' replacment.

FAAST by Notifier
FAAST is next-generation air-sampling from Notifier. Created by System Sensor, the worlds leading smoke detector manufacturer, the FAAST comes in several variants. FAAST LT is a device that sits on the Notifier detection loop and is intended for smaller applications. The FAAST 8100E is the premium model, with advanced features to eliminate false alarms while ensuring very high sensitivity.
With IP connectivity the FAAST can be monitorerd from anywhere in the world or it can send alert emails when issues arise. The PipeIQ software allows both configuration of the system and design of the pipework to be carried out in one software package.

What is Aspirating Smoke Detection?
- also called Air Sampling or EWSD (Early Warning Smoke Detection) it is the use of a distributed pipe network to sample air from the protected space and pass it through a sophisticated detector to detect small amounts of smoke indicating the early stages of combustion.
Cleanrooms and other hi-tech environments use air-movement to either keep the air moving through filters to clean it or to cool data-handling equipment such as servers. In these applications the air-changes are such that products of combustion will never accumulate at the ceiling level they way they are expected to do in normal rooms, where standard ceiling sensors would eventually trigger an alarm. Aspirating systems counteract the dispersal of smoke throughout the protected volume by drawing air in at many points and combining it at the detector. In addition the detector is extremely senstive and so can detect very small amounts of smoke, even if smoke is only entering one hole and clean air is entering the others. Chilled cold stores and warehouses with ceiling mounted chillers cause a similar effect, and aspirating systems are appropriate for protecting such installations. Other uses for aspirating systems are where concealed detection is required, and pipes can be hidden in ceilings and discrete sampling points used which can be cleverly disguised.
VIEW by Notifier
VIEW (Very Intelligent Early Warning) smoke sensors use a laser diode to provide sensitivity up to 100 times greater than a standard smoke detector. These sit on a Notifier detection loop like other addressable devices and so on a typical commercial installation high sensitivity can be easily achieved in IT rooms, Electrical Rooms, or other high risk areas very economically.
VIEW detectors can be set up to work co-operatively so that adjacent devices react quicker if both detectors see an increase in levels. The bright laser LED and sophisticated optics and algorithms mean that VIEWs can easily distinguish between smoke and dust particles and consequently are relatively immune to false alarms. There are 9 levels of Alarm( to 0.1%) and 9 levels of Pre-alarm (to 0.07%). VIEWs are an ideal choice for protecting a risk such as a seldom-visited electrical room or the floor void of an MCC room where rapid detection of smoke is vital. When grouped they can provide detection that compares favourably with air-sampling systems.
People are often surprised at the amount of smoke needed to trigger an alarm in a standard detector. That is because the accepted norms for detector sensitivity were laid down in an era when people could smoke at work, and the alarm level chosen was not simply the presence of smoke but the level of smoke at which people would be reluctant to move down a corridor. When you want early detection of smoke from a point-type addressable detector VIEW is the only way to go.
