Ionization Sensors are designed to detect fires with large open fire with a small amount of smoke. They are equipped with two metal plates and a small amount of radioactive material to ionize the air. When the smoke passes through the device, it interrupts the ionization and causes anxiety.
While the fire detector, in addition to the sensor itself, will include other elements, the number and composition of which depends on the specific model detectors. Thus, the design of the fire detector can include elements of signal recognition, exchange of information with other elements of automatic fire extinguishing system, re-inclusion system and other elements.
Dual-Mode detectors are capable of transmitting two signals – "Fire" and "No Fire". At first glance, the signal "No fire" seems superfluous, because the absence of the signal "Fire" just shows that there is no fire. But It is only at first sight.
The "No Fire" Signal indicates that the detector is healthy and "keeps track" of the situation. While the malfunction of a single-mode detector indicating that there is no fire, the total absence of a signal, it is possible to learn only in the course of the check, which nobody will arrange every day. Or when the irreparable happens. That is why the two-mode detectors are completely superseded by one-mode.
For detecting electrical fires, it's best to choose a smoke detector that has both photoelectric and ionization sensing technology. This combination helps detect different types of smoke, including smoldering fires (common in electrical fires) and fast-burning fires. Some highly-rated models include:
Nest Protect and First Alert Onelink Safe & Sound
This smart detector offers both smoke and carbon monoxide detection, with smartphone alerts and self-testing features. This unit combines smart technology with a powerful speaker and can connect with other smart devices. Kidde i9010 A reliable battery-operated smoke detector with a photoelectric sensor, ideal for catching smoldering fires early.
Best Places for Smoke Detectors
Bedrooms: Place a detector in each bedroom and outside sleeping areas. Hallways: Install detectors in hallways leading to bedrooms. Living Areas: Position detectors in common areas like the living room or family room. Kitchen: Install a heat detector instead of a smoke detector to avoid false alarms from cooking. Basement and Attics: Ensure there are detectors in these spaces, as electrical fires can occur in both.
Smoke rises, so mount detectors high on walls or ceilings. Test detectors monthly and replace batteries at least once a year. Replace smoke detectors every 10 years, as their sensors can degrade over time.
