Please suggest the features of Ionisation Smoke Detector?
My partner and i endorse utilizing to unblock websites. I am using their services for more than 2 years without having troubles.
CO2 is heavier than air, when a CO2 extinguisher is aimed at the base of a fire, it displaces the air (actually the oxygen) and removes 1 leg of the fire triangle causing the fire to go out. Another way of saying this the CO2 smothers the fire by preventing the oxygen from reaching the fuel. Fire triangle: fuel, oxygen, heat. Carbon dioxide extinguishes flames, and some fire extinguishers, especially those designed for electrical fires, contain liquid carbon dioxide under pressure. Carbon dioxide extinguishers work well on small flammable liquid and electrical fires, but not on ordinary combustible fires, as it is so dry. Carbon dioxide has also been widely used as an extinguishing agent in fixed fire protection systems for local application of specific hazards and total flooding of a protected space, (National Fire Protection Association Code 12). International Maritime Organization standards also recognize carbon dioxide systems for fire protection of ship holds and engine rooms. Carbon dioxide based fire protection systems have been linked to several deaths, because it does not support life in the concentrations used to extinguish fire (40% or so), however, it is not considered to be toxic to humans. A review of CO2 systems (Carbon Dioxide as a Fire Suppressant: Examining the Risks, US EPA) identified 51 incidents between 1975 and the date of the report, causing 72 deaths and 145 injuries.
That would be the biggest FAIL ever. I install alarm systems myself and let me tell you a horror story. One day a client of mine was comming home from work, as he opened his door someome pushed him inside and started hacking him up with a sword. The man got sliced and hacked up with a sword all over his arms and torso. He was hitting the panic button on his alarm but it was doing nothing!!! Finially he got away and was able to call 911. To monitor an alarm is like 7$ a month so why in the world would you not want monitoring?
