Conventional Fire Alarm System Composition
Conventional Fire Alarm  System consists of:
Conventional Fire Alarm Control Panel,Smoke Detector ,Heat Detector ,Beam Smoke Detector,Entrance LED Indicator etc.

Scope Of Application
Conventional Fire Alarm System is mainly suitable for protecting industrial and civil construction  (such as civil residences, office buildings, warehouses, etc.). The nature of use, fire hazard, and difficulty of evacuation differ for different protected objects. It should be designed and used in conjunction with the fire alarm system according to the actual situation.

Conventional Fire alarm system How to detect fire
A. Smoke Detector
(1) The smoke detector is to realize fire prevention by monitoring the concentration of smoke, and the ion smoke sensor is used internally.
(2) AW-CSD381 is a conventional photoelectric smoke detector using the most advanced optical sensing cavity. The detector is designed to provide open area protection and can be used with most conventional fire alarm panels. The two LEDs on each detector provide a local 360 ° visible alarm indication. They flash every six seconds, indicating that the power is on and the detector is working properly. The LED will be locked in the detector.

B. Heat detector
The temperature-sensitive alarm is also called Heat Detector. The burning of substances during a fire generates a lot of heat, which causes the surrounding temperature to change. A heat detector is a fire detector that responds to temperature changes at a certain point in the warning range or around a certain line. It is to convert temperature changes into electrical signals to achieve the purpose of alarm.

C. Beam Smoke Detector 
(1) Beam smoke detectors use infrared to form a detection source, and use the diffusivity of smoke to detect fires within a fixed range around infrared. Linear beam smoke detectors are usually composed of separately installed and calibrated infrared Paired by the light emitter and the light receiver;
(2) Its working principle is to use the smoke to reduce the amount of light emitted by the infrared light emitter to the infrared receiver to determine the fire. This fire detection method is usually called the smoke reduction method.

D. Flame detector
The flame detector is to detect the smoke and heat generated when the substance burns, and also produce visible or invisible light radiation that is not in the atmosphere.
