GST Intelligent Smoke Detector is the ideal device for most application due to its excellent linear response to a wide variety of different type of smoke patterns. The unit meets the sensitivity requirement of UL 268 Standard for Smoke Detector for Fire Protective Signaling System Aesthetically pleasing with a low profile design, unobtrusive to complement modern building designs. The unit incorporates an intelligent processor that provides Algorithm map, Built-in A/D converter, Drift compensation, Self Diagnosis and history log. The integral microprocessor analysis the signal according to the factors such as signal strength and rate of increase, then confirms these pattern with the pre-programmed fire scenarios and smoke patterns for a faster and safer response. By intelligent analysis, the smoke detection sensitivity will be automatically adjusted according to temperature change, providing a rapid response. Secure and speedy communication through the onboard processor enables the detector to make its own decision, resulting in greater automation. The sensor and the panels utilized fuzzy logic providing an almost limitless cause and effect scenarios. Drift compensation, to monitor for the long-term changes caused by ageing, humidity, temperature, dust, etc. constant monitoring and self-adjusting, the I-9102 UL updates sensitivity baseline for its sensing element. Even when the detector raises a warning advising that it requires cleaning, the sensitivity remains the same as the day it was installed. Electronic addressing can be done through Handhold Programming device (P-9910B), purchased separately.

Pre Action Fire Sprinkler Systems employ the basic concept of a dry pipe system in that water is not normally contained within the pipes. The difference, however, is that water is held from piping by an electrically operated valve, known as a pre-action valve. Valve operation is controlled by independent flame, heat, or smoke detection.
Two separate events must happen to initiate sprinkler discharge. First, the detection system must identify a developing fire and then open the pre-action valve. This allows water to flow into system piping, which effectively creates a wet pipe sprinkler system. Second, individual sprinkler heads must release to permit water flow onto the fire.
In some instances, the pre-action fire sprinkler system may be set up with a double interlock in which pressurized air or nitrogen is added to system piping. The purpose of this feature is two-fold: first to monitor piping for leaks and second to hold water from system piping in the event of inadvertent detector operation. The most common application for this system type is in freezer warehouses.
Advantages of using pre-action fire sprinkler systems include:
The dual action required for water release - The pre-action valve must operate and sprinkler heads must fuse. This feature provides an added level of protection against inadvertent discharge. For this reason, pre-action systems are frequently employed in water sensitive environments such as archival vaults, fine art storage rooms, rare book libraries and computer centers.
Disadvantages of using pre-action fire sprinkler systems include:
Higher installation and maintenance costs - Pre-action systems are more complex with several additional components, notably a fire detection system. This adds to the overall system cost.
Modification difficulties - As with dry-pipe systems, pre-action sprinkler systems have specific size limitations which may impact future system modifications. In addition, system modifications must incorporate changes to the fire detection and control system to ensure proper operation.
Potential decreased reliability - The higher level of complexity associated with pre-action systems creates an increased chance that something may not work when needed. Regular maintenance is essential to ensure reliability

Protect a facility and its high-value assets
such as tools, equipment, product and data
by catching a fire before there’s smoke!
FAAST provides facility managers and equipment owners with various levels of alert at the earliest stages of a fire, as early as 60 minutes before combustion. Your assets are protected from the damaging effects of the faintest traces of smoke, while precious time is made available for appropriate action by safety personnel. With this very early fire and smoke detection, you protect people and assets, maintain business continuity and ensure productivity.
FAAST also helps facilities run smarter and smoother. The FAAST
sensing technology is extremely sensitive, so it works precisely the way it was designed to, which ensures uptime. In Acclimate™ mode, the detector automatically adjusts itself to current environmental conditions, so you avoid nuisance alarms that can lead to costly downtime and unwarranted activation of suppression systems, which can damage sensitive machinery
