Fire Alarm Systems

As we know residential fires have become a burning topic nowadays. Most of the lives are lost due to residential fires. This can be prevented by installing smoke alarm and fire alarm systems in the residential and official premises. Smoke detectors and heat detectors are used in these smoke alarm and fire alarm systems. The type of detector which operates based on detection of smoke and consecutively generates alarm or signal is known as smoke detector(alarm).
The types of smoke detectors
• Photoelectric smoke detector
• Ionization smoke detector
• Laser based smoke detector
• Aspiration smoke detector
• Air Sampling detector
Smoke detectors have saved thousands of lives in Canada since their introduction and widespread use during the past 2 decades. The good news is that more than 95% of homes in Canada now have at least 1 smoke alarm. The bad news is that a substantial proportion of those smoke detectors (alarms) do not work. In on-site surveys of homes with smoke alarms, about 28% to 35% of the alarms did not function when tested. Some failures are due to malfunction of the alarm itself, some are due to a dead battery, and some do not function because the battery has been removed.
Smoke alarms will probably continue for the foreseeable future to be one of the most important means of preventing fire-related deaths. Homes at highest risk of fire and fire-related deaths and injuries are those least likely to have smoke alarms—that is, homes in the lowest socio-economic neighborhoods and those of substandard quality. Identifying those homes and ensuring that they have smoke alarms installed are challenging public health issues. Systematic use of surveillance data to identify deaths and injuries due to house fires is essential to focus resources into neighborhoods at greatest risk and where the greatest benefit may be inured. Once identified, these areas can be the target of efforts to increase the prevalence of smoke alarms in Ontario, such as through mass smoke alarm distributions.
Kids and smoke detectors
The most recent research indicates that sleeping children don’t always awake when a smoke alarm activates. While this research is worrisome, we shouldn’t allow them to obscure the fact that smoke alarms are highly effective at reducing fire deaths and injuries. It definitely reaffirms the value of the smoke alarms already available to protect people from house fire deaths and voice its concern about the number of households without these early warning devices. While 87% of Canadian houses have at least one smoke alarm, no smoke alarms were present or none operated in two out of five (39%) of the reported home fires between 2004-2007. Almost two-thirds of home fire deaths resulted from fires in homes with no smoke alarms or no working smoke alarms.
There is a higher demand to continue planning and practicing home fire escape plans and to make sure everyone in a home can be awakened by the sound of the smoke alarm. CFAA suggests practicing the escape plan during which the smoke alarm is activated so all family members know its sound. Every home fire escape plan is different, and every family should know who will – and who won’t – awaken at the sound of the smoke alarm. If someone doesn’t wake up when the alarm sounds during a drill, the family should design an escape plan that assigns a grown-up who is easily awakened by the alarm to wake the sleepers, perhaps by yelling “FIRE,” pounding on the wall or door, or blowing a whistle.
Plan your escape
Your ability to get out of your house during a fire depends on advance warning from smoke alarms and advance planning.
• Get everyone in your household together and make a home escape plan.
• Make sure escape routes are clear of debris and doors and windows open easily.
• Plan an outside meeting place where everyone will meet once they have escaped.
• If there are infants, older adults, family members with mobility limitations or children who do not wake to the sound of the smoke alarm, make sure that someone is assigned to assist them in the event of an emergency.
• If the smoke alarm sounds, get outside and stay outside.
