Review SYSTEM SENSOR D4120 Photoelectricsmoke24vac/dc120v Oem

The Sensirion D-4120 photoelectric smoke sensor is a versatile and reliable device designed for use in fire detection systems. This sensor is suitable for both AC and DC power supplies, with operating voltages ranging from 24V AC to 120V.

The heart of this sensor is a high-sensitivity photoelectric smoke chamber. It employs a light source and a light-scattering sensor that detects the presence of smoke particles in the air. When smoke enters the chamber, it scatters the light, causing a change in the sensor's output signal. This change in signal is then transmitted to the fire alarm control unit, triggering the alarm.

The D-4120 sensor is designed with a robust and compact housing, making it suitable for various installation environments. It features a threaded base for easy mounting on a DIN rail or other surfaces. The sensor also comes with a protective grille, which not only prevents dust and insects from entering the sensor but also ensures that the sensor's light source is not accidentally covered or obstructed.

The sensor has a number of advanced features to ensure reliable and accurate smoke detection. It has a self-test function, which periodically checks the sensor's functionality and reports any faults to the control unit. The sensor also features a temperature compensation function, which helps maintain accurate and stable sensor output over a wide temperature range.

The Sensirion D-4120 photoelectric smoke sensor is an essential component in fire detection systems, providing early warning of potential fires and ensuring the safety of people and property. With its wide voltage range, robust design, and advanced features, this sensor is a reliable and cost-effective solution for fire detection applications.
