Smoke Detectors and CO Detectors

Are smoke detectors and CO detectors the same? Smoke detectors and CO detectors are two different instruments with distinct differences in nature. Next, we will provide you with detailed information to explain their differences in different aspects.

Smoke Detector Basics Carbon Dioxide Smoke Detector

Smoke detectors, also known as smoke detectors, are mainly used in fire protection systems and security systems. It is a typical device converted from space firefighting measures to civilian use. The internal smoke detector uses an ion smoke sensor, which is a technologically advanced, stable and reliable sensor. It is widely used in various fire alarm systems, and its performance is far superior to gas sensitive resistance fire alarms.

The ionization chamber inside and outside the smoke detector is equipped with radioactive source Americium 241, and the positive and negative ions produced by ionization move to the positive and negative electrodes respectively under the action of the electric field. Under normal circumstances, the current and voltage of the inner and outer ionization chambers are stable. Once there is smoke escaping the ionization chamber. It interferes with the normal movement of charged particles, changes the current and voltage, and destroys the balance of the inner and outer ionization chambers. Then the wireless transmitter sends out a wireless alarm signal, notifies the remote receiving host, and transmits the alarm information.

Carbon monoxide gas detector

A carbon monoxide detector or CO detector is a device that detects the presence of carbon monoxide (CO) gas to prevent carbon monoxide poisoning. Carbon monoxide is a colorless, tasteless, and odorless gas. It is often referred to as the "silent killer" because humans are barely aware of it. According to a study , "60% of Americans are unaware of any potential signs of carbon monoxide leaks in their homes". High concentrations of CO can be dangerous to humans depending on the amount present and the length of exposure. Smaller concentrations can be harmful over longer periods of time, while increasing concentrations require reduced exposure time to be harmful.

NDIR Modules Detect CO Gas

Carbon monoxide detectors are designed to measure carbon monoxide concentrations over time and sound an alarm before dangerous levels of carbon monoxide are reached in the environment, giving people enough warning to safely ventilate or evacuate the area. Detectors connected to some systems also alert monitoring services so that emergency services can be dispatched if necessary.

A CO detector cannot be used as a smoke detector or vice versa, but people also sell combination smoke/carbon monoxide detectors.
