Surjit Gautum who has been a source of perpetual inspiration to us, gently guiding and our waves towards a bright career. You were ever willing to give all kind of support and encouragement. In the end we want to thankful our “Parents”, “teachers” and Almighty GOD for the entire thing that they do to us.Security is a prime concern in our day-today life. Every country as well as individual wants to be as much secure as possible. Recent activities in the major cities have made it more important than ever to take adequate steps to maintain the safety of the home and the personals.
At times like a fire breakout where immediate and appropriate actions are required, things are required to be made automated because under panic conditions the response time of a normal human brain increases. There can be many solutions possible for implementing such a system. According to the U. S. Fire Administration, the number of fires in residential dwellings (one and two-family homes, apartment buildings, hotels and other boarding facilities) in 2007 was 414,000 — an increase of approximately 9. 2% from 1998.
During the same period, the direct dollar property losses nearly doubled, going from $4. 4 billion to over $7. 5 billion. It is worth noting however that the number of fire deaths and injuries over this same nine-year period have generally decreased; overall, these figures have declined by approximately 8. 3%. Still, there were 2,895 deaths and 14,000 fire-related injuries during 2007. The decline in the death and injury rate can be attributed to better fire alarm system monitoring technology, and points up the importance of such technology in your home.
The Essay on Dorm Fire Safety
How can students prevent dorm fires? The answer to that question may seem simple but that doesn’t change the fact that residence hall fires are a growing problem in colleges across the nation. Students use of basic electronic cooking utensils such as microwaves, smoking products, candles or incense are all different entities that can start fires in dorms. Dorm room fires can lead to serious injury ...
Although most of us use reasonable caution, home fires have been known to start from all sorts of causes — including short circuits in the defective wiring of the inferior appliances now manufactured in substandard facilities in China and Mexico. In fact, older televisions can be turned off and unplugged and still cause fires for up to 24 hours because of electrical energy stored in the transducer; in 2006, a number of Chinese-manufactured Dell laptops mysteriously exploded for no apparent reason.
When we are asleep, our senses are asleep as well; therefore, it is possible to burn alive (though asphyxiation usually occurs first — mercifully) without ever being aware of it. Because heat, which rises and gathers toward the ceiling, is the first warning sign of a fire, a good fire alarm monitoring system should have heat detection sensors as well as smoke detection sensors. Ideally, these are mechanical and not electronic in nature, since a building fire can put the electrical system out of commission in short order.
Otherwise, your heat and smoke detection systems, if hard-wired in to the home electrical system, must have battery backup; this battery should be replaced at least once every year. Security systems designed to detect unauthorized entry into a building or area. They consist of an array of sensors, a control panel and alerting system, and interconnections. Sensors detect intruders by many methods such as monitoring door and window contacts, by passive infrared motion detectors, ultrasound, vibration, electric or magnetic fields, or microwaves.
Sensors may be directly wired to a control panel that provides sensor power, or may communicate wirelessly. Some alarm systems serve a single purpose of burglar or fire protection. Combination systems provide both fire and intrusion protection. .
The Term Paper on Heat Pump
Outdoor components of a residential air-source heat pump A heat pump is a machine or device that transfers thermal energy from one location, called the “source,” which is at a lower temperature, to another location called the “sink” or “heat sink”, which is at a higher temperature. Thus, heat pumps moves thermal energy opposite to the direction that it normally ...
