A smoke detector is a device worth investing in. It will work well not only in a house, but also in an apartment or a public building. It is important to remember that it increases safety and can provide additional protection for people and property. Today we will tell you how smoke detectors work. We will also present their advantages and really good models.

How does a smoke detector work?
The principle of operation of a smoke detector is very simple. It most often uses the phenomenon of light absorption and its dispersion. The smoke detector contains an emitter that sends out a beam of infrared light. If smoke appears in the room, the beam is absorbed. This causes an anomaly between the emitted and received beam, which in turn triggers an alarm. When smoke is sensed, a siren starts howling, which is usually 80 dB loud. A colored diode may also flash. Dispersive optical sensors are also available. These devices determine the condition of the air. When smoke enters the sensor, the infrared radiation beam is disrupted and an alarm is triggered.
Fire statistics are downright terrifying. Imagine that there are 30,000 house and apartment fires every year. Unfortunately, most places where fires occurred did not have a smoke detector. It is worth knowing that this device really does improve safety to the maximum extent, because it quickly and effectively detects smoke, which can, for example, rise from a burning pan or a malfunctioning electrical installation. Most often, fires are caused by human error. A fire can even be caused by a cigarette butt. Smoke is the first symptom of a fire. The truth is that the sooner it is detected, the sooner all household members or building users can be evacuated efficiently, but there is also a chance to save property.
What does a smoke detector detect?
The smoke sensor, as the name suggests, detects smoke, e.g. smoke rising from a damaged 
installations or improperly functioning electrical devices, or even a burnt kettle. The smoke sensor therefore responds to light dispersed by smoke particles. The device contains a sensor built from pipe systems. It is into these systems that air is sucked from the protected space. Many people wonder whether the smoke sensor will also respond to e-cigarettes? It is worth knowing that it will, but when the e-cigarette is vaporized. For example, it can ignite during charging and cause a fire, which is why you should pay special attention to safety when using this type of device.
How do I turn off the smoke detector?
Smoke detectors are basically almost maintenance-free devices. Deactivating the device is very easy. Most often, all you need to do is hold the casing visible from the bottom until the alarm signal stops. The LED may then flash, signaling that the detector is deactivated. If the smoke detector has detected a threat that you have already dealt with, it may turn out that the device still has an alarm on due to smoke. In this case, you can reset the alarm, or you can remove the battery and then reinsert it. It is also necessary to ventilate the entire room so that the smoke is imperceptible and invisible.

Kidde 2030-DSR
If you are looking for a reliable device, choose the Kidde smoke detector , which is characterized not only by its aesthetic finish and small size, but also by a high-quality optical sensor. If smoke is detected, the device triggers a loud alarm. It is worth noting that the test and hush buttons are used to control and operate this device. It is worth noting that the detector has a low voltage signal. For greater safety, it also signals a discharged battery. It can be installed not only in the living room or lounge, but also in the bathroom, near kitchens or even in high rooms.
Honeywell Home R200S - 2
Our list could not be complete without the Honeywell Home smoke detector . It is an optical sensor that is battery-powered. It can be easily mounted on both the wall and the ceiling. It has a tightness class of IP 20. When it detects danger, it gives both an audible and visual signal. It also has a mute function and a low battery warning.
Honeywell Home with radio communication function
Another good choice is the Honeywell Home smoke detector with radio communication . It works great not only in residential houses, but also in caravans. It is equipped with an automatic self-test. You can silence it for 10 minutes. The radio communication function is also worth noting. Thanks to it, you can connect sensors into a wireless network and synchronise their operation.
