Conventional fire alarm systems: which one should I install in my home?

Installing one of these systems in your home could save your life in the event of a fire.
Before choosing which fire alarm system best suits your needs, it is necessary to know its features. In the following article, we will explain how each of these fire alarm systems works.
Smoke detectors:

These systems detect fire in the early stages, and there are two fundamental activation principles: the ionization chamber type (these are especially sensitive detectors but they’re obsolete) and the optical type (these are detectors with photoelectric cells that when darkened by smoke or illuminated by the reflection of light in the smoke particles, are activated, originating an electrical signal.)

Temperature detectors

These types are the least sensitive, although they generally have bigger resistance to environmental conditions. They’re classified as thermal detectors and are activated when a fixed temperature is reached in the environment; thermo-velocimetric detectors are activated when the ambient temperature has increased rapidly.

CO detectors

Carbon monoxide is a deadly gas that can be released into your home through faulty heating and cooling equipment. It is odorless and undetectable to humans. These systems can be used alone or in combination with other detectors.

Analog Control Panels:

In this type of system, the detectors become “sensors” that transmit information on how much smoke or heat is being perceived. Once the control panel has been configured, it will sound the alarm based on the information received when it does not agree with the previously programmed values.
