The new Gira Dual Q smoke detector is equipped with two detection methods, making it particularly safe. It detects small smoke particles both optically and sensorily, while heat sensors measure temperature changes in the room. This allows for quicker registration and reliable detection of different types of fires, such as liquid fires. Are you looking for a smoke detector that won't be distracted by kitchen vapors, dust, or electronic interference? In these cases, the Gira Dual Q smoke detector is an excellent choice.
