Fire detection system designIn order to correctly design fire detection systems, one must take into account various criteria.
Included are: burning, possible ways of catching fire, the effects of ceiling height and configuration, room ventilation and temperature.
These systems are generally intended to detect and extinguish fires before great damage is done. Active protection can be divided into fire detecting systems and fire extinguishing systems.
The first include various fire, smoke, heat and flame detectors.
Fire detection system design criteria must include basic system functions like: Informing people present in the building about the status of the system and evacuation conditions, alerting the fire department, detecting specific stages of fire(smoke or burning) and fire development, activating the fire extinguishing system, as well supervising it in order to notice irregularities caused by the fire.
The criteria are the basics of fire detection systems design. They provide system specification parameters and are used in construction schemes and detailed specifications. They must include engineering studies of every area which define the type of fire and possible fire development in the area.
When designing the system, one must take into account constructional functions of the installation. For optimal detector distribution, the height and construction type of the ceeling is also important. Other important parameters include ventilation and temperature of every area. In the analyzing part of designing, natural as well as artificial air currents must be defined.
Criteria of design determine functions and operation of the system as a whole.
