The fire detectors are fire surveillance measures using.The alarm. One reason or order to end before the fire or progression. The main purpose of fire detection is to stimulate a response alarm occurs, such as suspension of fire.Transport property. At present, the detector shows the malfunction about the speed ในการตรวจจับ. And reliability of the equipment efficiency in works by European standards, EN54But did not cover the resistance test false alerts from disturbing events such as Smoke from cigarette smoking and dust from construction of smoke detectorsAnd also to the accuracy and reliability in calculation of response times of detection equipment heat can be estimated accurately capture detector detection period of heat each kind to the left.Safe design and choose the suitable environment and areas such as to satisfyLong narrow area on the boat and also the techniques in detecting fire new surface area dynamic help in surveillance and reduce the severity and impact of the fire.
