How does a smoke detector work?
The principle of operation of a smoke detector is very simple. Well, it most often uses the phenomenon of light absorption and its scattering. The smoke detector contains an emitter that sends a beam of infrared light. If smoke appears in the room, the beam is absorbed. Therefore, there is an anomaly between the transmitted and received ray, which in turn triggers an alarm. When smoke is detected, the siren begins to sound, most often with a volume of 80 dB. The colored LED 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 occurs.
The fire statistics are downright terrifying. Imagine that it reaches 30,000 every year. house and apartment fires. Unfortunately, most places where fires occurred did not have smoke detectors. It is worth knowing that this device actually improves safety to the maximum extent, as it quickly and effectively detects smoke that may, for example, arise from a burning frying pan or a malfunctioning electrical installation. Most often, fires occur as a result of 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 and building users can be evacuated efficiently, but there is also a chance to save the property.
What does a smoke detector detect?
The smoke sensor, as the name suggests, detects smoke, e.g. rising from a damaged one 
installations or improperly functioning electrical devices, or even a burnt kettle. The smoke detector therefore responds to the light scattered by smoke particles. The device contains a detector made of pipe systems. Air from the protected space is sucked into these systems. Many people wonder whether the smoke detector will also respond to e-cigarettes? It is worth knowing that yes, but only when the e-cigarette is vaporized. For example, it may catch fire during charging and cause a fire, so you should pay special attention to safety when using this type of devices.
How to turn off the smoke detector?
Smoke detectors are essentially almost maintenance-free devices. Turning off the device is very easy. Most often, all you need to do is hold the casing visible from the bottom until the alarm signal turns off. The LED may then flash to indicate that the sensor 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 due to smoke. In this case, you can reset the alarm or 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 an aesthetic finish and small size, but also by a high-quality optical sensor. If smoke is detected, the device sounds a loud alarm. It is worth noting that test and hush buttons are used to control and operate this device. It is worth noting that the sensor has a low supply voltage indication. For greater safety, it also signals when the battery is discharged. It can be installed not only in the living room or living room, but also in the bathroom, near the kitchen or even in high rooms.
Honeywell Home R200S - 2
Our list also includes a product called the Honeywell Home smoke detector . It is an optical sensor that is battery-powered. It can be easily mounted on both the wall and ceiling. It has a tightness class of IP 20. When danger is detected, it gives both an acoustic and visual signal. It also has a mute function and a low battery warning.
Honeywell Home with radio communication function
A Honeywell Home smoke detector with radio communication function is also a good choice. It works great not only in residential houses, but also in caravans. It is equipped with an automatic self-test. You can mute it for 10 minutes. The radio communication function is also worth mentioning. Thanks to it, you can connect sensors into a wireless network and synchronize their operation.
