Nursing homes to install wireless smoke alarm system in time to avoid the tragedy

    Now with the accelerating the aging of the population rapidly, the rapid development of the nursing home, the old man´s body is more bad, lack of fire self-help ability, 25, a nursing home fire in henan, killed 38 people, 2, 4 passengers were slightly injured seriously, the cause is circuit out of the question, a tragedy that tell us to support the old man is not only our responsibility and obligation, and should we pay attention to fire prevention, a safe and comfortable environment, to old people now DianQiHua increase, every line is likely to be a fire, in order to this tragedy no longer occur, the shenzhen armoured WeiXin safety technology co., LTD., independent research and development to produce a JTY GD - DG802 independent type photoelectric smoke detector, a nursing home fire alarm equipment, etc.

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

JTY GD - DG802 independent type photoelectric smoke detector for 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.

In order to the old man´s health and safety, I hope I didn´t install smoke alarm system of the nursing home to take notice, install smoke alarms in a timely manner.
