Automatic fire alarm system

Taking advantage of some used thermal sensors, Nguyen Duc Nhan, lecturer of the Faculty of Electrical Engineering - Quang Binh Agricultural and Industrial Vocational School has successfully researched and manufactured a local fire and fire alarm system. , can be applied in many small, medium and large projects.

Before the situation of fire and fire alarm methods is often complicated: it is difficult to detect the location of the fire early, it is difficult to control fire, Nguyen Duc Nhan (1981) spent nearly a year (from 11/2010 to 8/2011). Research and successfully manufacture a simple, low cost, high-performance fire and fire alarm system.

Model of local fire alarm and fire fighting system by Nguyen Duc Nhan

Local automatic fire alarm and fire alarm system, simple design, including some thermal sensors in air-conditioners, air-conditioners . used, sirens, signaling systems, fire systems , pump, water valve. The new thing here is to overcome some disadvantages in fire prevention and fighting, which are: Helping people to quickly discover, accurately position fire with sirens, signal lights . simultaneously, activate the system automatically Early fire action to reduce damage caused by fire.

The fire alarm system operates according to the principle, when smoke appears, the sensor head senses smoke will signal the center with lights and sirens, signaling people around ready to deal with the fire. Local fire-fighting system with water, sand will automatically activate when the temperature in the fire area exceeds 50 degrees C (exceeding the permitted level), automatically cut off the power at the place where the fire occurs to avoid short-circuit. In areas where there is no fire and if fire spreads, the sensor will continue to operate and fire when necessary.

The local system of automatic fire alarm and firefighting has reached the top 68 topics of 'National Youth Creation' in 2011, which was praised at the national festival of "Creative Youth and Environment Protection". in Hue in the middle of last October.
