Recognize how fire alarm equipment is classified and avoid loss of procurement
Fire alarm equipment includes fire detectors, alarm buttons, alarms, and fire alarm controllers. In the purchase of fire alarm equipment, be sure to check whether the product has national mandatory 3C certification, China does not allow products for 3C certification is not allowed to be used for fire engineering, so procurement must be clear and avoid unnecessary losses. Here we introduce the detailed classification and use of fire alarm equipment.
Fire detectors include temperature-sensitive fire detectors, smoke detectors, composite smoke detectors, ultraviolet flame detectors, combustible gas fire detectors, and infrared fire detectors. When the smoke concentration or temperature reaches the detector's response value, the alarm is returned and the signal is transmitted back to the alarm controller.
The manual fire alarm button and fire hydrant button are assigned to the alarm button. When a person discovers a fire but the detector does not detect a fire, the person manually presses the fire alarm and fires a signal. When the fire button alarm is reported manually under normal circumstances, the probability of a fire is much greater than that of a fire detector, and there is almost no possibility of false alarms. Because the manual fire alarm button alarm starting conditions must be manually pressed to start the button, press the manual alarm button on the 3-5 seconds button on the fire confirmation light will light, this status light indicates that the fire alarm controller has received the fire alarm signal, and Confirmed the site location. The fire hydrant button is used to start the fire pump. If the system has a fire pump, the fire hydrant start button should be set, otherwise it is not required.
Alarms include fire alarms, fire alarms, and fire alarms. The sound and light alarm system has a stainless steel housing, and the lamp housing has strong anti-impact capability. The 180 clear-view super bright LED LED tube is equipped with a super buzzer. It has stable working performance, long service life, and low power consumption. Affected by pollutants and water.
