According to definition, a fire alarm system is a number of devices that are put together to work together in detecting and warning people via audio and visual appliances when there is a presence of carbon monoxide, fire, smoke or any other emergency. They are most times triggered by heat detectors or smoke detectors and can either be wall mountable horns or motorised chimes and can make use of a Lithonia battery. Most of the fire alarm systems have speakers that sound an alarm and also a voice message that usually states emergency warning on how to evacuate the building; what not to do and where not to go when there is a heat, smoke, or fire detection.

The placing of smoke alarms should be made on each area of your house and outside every sleeping area in your home. In the cases of the bedroom doors being closed, there should be extra alarms placed inside the various bedrooms. The installation of smoke alarms should always be placed on the ceilings and away from drafts from windows or air ducts; this is because smokes rise up. Always ensure you follow the installation instructions by the manufacturer and also ensure you verify all compliance and codes with your local authority.

Fire alarm system

There are two different types of fire alarms systems, smoke alarms and heat alarms. Knowing the different types of fire alarms, and the differences between the various types of fire alarms that are available is a sure key for you to choose the appropriate one for you.

HEAT DETECTORS

Among the types of automatic fire detection device is the heat detectors, and they are known to be the oldest among them all. A heat detector always contain a detecting device inside the unit that triggers when it reaches a programmed specific temperature, or when there is an increase in the set temperature. They are best suitable for:

  • Fire detection in little, limited spaces where quick burning and climaxed heat fires are expected.
  • Application where speed of detection is not a main deliberation.
  • Where the use of smoke detector will not be allow by the ambient conditions.

HEAT DETECTORS

The truth about heat detectors is that they have a very low false alarm rate, but are slower than smoke detectors in detecting potential fires. According to studies, heat detectors are not effective in the detection of fire in residential homes.

SMOKE DETECTORS

Smoke detectors are types of automatic fire detection device that work more efficiently and effective than heat detectors. Smoke detectors rapidly detect fire in residential homes and that is why a lot of residents and home owners opt for them when it comes to choosing a fire alarm system. These smoke detectors are programmed in such a way that, when there is a change in the ambient conditions of a place and it turns out to be a smoke, they will alert people that are around and some of them make use of a Lithonia battery. There are various types of smoke detectors, and they are:

  • Ionization alarms.
  • Photoelectric alarms.
  • Combination of ionization and photoelectric alarms.
