Chemical industry smoke by armoured WeiXin safety technology independent research and development production of a dedicated to the family, the facade, shops, factories, and other small places fire monitoring alarm smoke detector. The type of photoelectric smoke detector controlled by MCU, can have an intelligent judgment of fire smoke and timely report to the police, with excellent production technology, stable performance, beautiful appearance, simple installation, do not need to debug, and many other advantages, once launched, the popular.
Separately using photoelectric smoke detector don´t have to worry about the radiation of the problems of traditional ionization smoke detector, and the type smoke detector using 9 v battery, without external wiring, installation itself does not affect the family decorates pattern, also more secure. Detector minimal power consumption, continuous working time can reach more than 1 year.
The performance characteristics of
Using new type of high-performance sensors, can perceive the happening of the smoldering fire effectively
The smoke detector adopts the professional chip design, stable performance
Smoke outside the maze has a bug net, can effectively avoid the insects go and report to the police
With LED lights, can display the normal working state and alarm status
The outer flame retardant type fireproof ABS plastic, beautiful and easy, more reliable

The working principle of
Chemical industry smoke to smoke induction is mainly completed by optical maze, maze contains a set of infrared emission and receiving phototube, correlation Angle of 135 degrees. When the environment without smoke, you can´t get a infrared receiving tube infrared transmitting tube from the subsequent no electrical signal sampling circuit; When environment have a smoke, the smoke particles into the maze to tubes of infrared light scattering occurs, the intensity of the infrared light scattering has a certain linear relationship with the smoke concentration, subsequent change sampling circuit, through the smoke detector built-in MCU to judge whether these changes to confirm the amount of fire, once the confirmation of fire, smoke detector signal fire, the fire light (red) light, and start the buzzer alarm.
Functional specifications
The chemical industry smoke has the following features:
Test function: when the smoke detector installed after the power is connected, the LED light is probably every 50 s just flashing once, said its already in normal working condition. The above test button then press the detector, detector built-in buzzer will send out alarm, light LED indicators at the same time; Loosen the test button, the probe will back into the normal working condition. Note: the user is recommended every once in a while just to a smoke detector test, ensure it has been in normal working condition.
Alarm function: when the smoke detector to detect the surrounding environments of smoke concentration reached alarm threshold, the LED will quickly flashing lights, keep normally on after about 5 s, buzzer alarm will be issued at the same time. After the smoke concentration lower, smoke detector automatically return to normal working condition.
Under-voltage remind: when the smoke detector battery voltage level is less than 7.5 V, the detector will be a squeaking "drops" sound and instructions, buzzer about 50 s function call, the alert users to replace the battery in time.
Matters needing attention
The chemical industry smoke optimum not installed in the following places:
Under normal circumstances the places where smoke retention
Have larger dust, oil, steam and corrosive gas
Ventilation speed greater than 5 m/s
Relative humidity is more than 95%
