A Fire Suppression System must be able to absorb the heat energy from the combustion reaction at the molecular level. The ability to absorb more heat than the amount being generated by the combustion reaction is most essentially for fire to be contained.
This means that the system installed must be able to interfere with the chain reaction of the combustion process as it aids in the extinction of the fire. For a Fire Suppression System to be most effective, it should be automatic.
There are numerous types of Automatic Fire Suppression Systems. These systems are as diverse as their many applications. In general, however, Automatic Fire Suppression Systems fall into two categories – engineered and pre-engineered.
Engineered Fire Suppression Systems are design specific. They are usually large installations where the system is customized for a particular application. Examples include marine and land vehicle applications, computer clean rooms, public and private buildings, industrial paint lines, dip tanks and electrical switch rooms.
Pre-Engineered Fire Suppression Systems do not require modification beyond the original product design. Pre-engineered systems are made of pre-designed components. Examples of Pre-engineered Suppression Systems include commercial kitchen systems, and industrial storage areas.
Pre-engineered Suppression Systems most commonly use a simple wet or dry chemical agent such as potassium carbonate or mono-ammonium phosphate (MAP). Engineered systems use a number of gaseous or solid agents. Many are specifically formulated.
By definition, an automatic Fire Suppression System can operate without human intervention. To do so it must possess some means of detection, actuation, and delivery.
In many systems, detection is accomplished by mechanical or electrical means. Mechanical detection uses fusible-link or thermo-bulb detectors. These detectors are designed to separate at a specific temperature and release tension on a prescribed mechanism.
Electrical detection utilizes heat detectors equipped with self-restoring, normally open contacts which close when a predetermined temperature is reached. Remote and local manual operation is also possible.
Delivery is accomplished by means of piping and nozzles. Nozzle design is specific to the agent used and coverage desired.
