Polon-Alfa DOP-40R Optical linear smoke detector(1PCS)

POLON-ALFA DOP-40R Optical Linear Smoke Detector (EN 54-12, 5-100m Range)

The POLON-ALFA DOP-40R is a reliable Optical Linear Smoke Detector, designed and manufactured by POLON-ALFA in the EU. This type of detector is an essential component in fire alarm systems, specifically engineered for protecting large open indoor areas where traditional point smoke detectors may not be practical or cost-effective.

The DOP-40R operates by emitting a beam of infrared light from a transmitter unit (often housed with the receiver in a single head) towards a reflector or a receiving unit placed on the opposite side of the protected area. It constantly monitors the intensity of the received light beam. When smoke enters the path of the beam, it attenuates the light, and the detector registers this reduction as an indication of smoke, triggering an alarm.

This model is compliant with the European standard EN 54-12, which specifies the requirements for line-type smoke detectors using an optical light beam. It has an adjustable operating distance range of 5 to 100 meters, making it suitable for spaces of various sizes, including warehouses, factories, sports halls, and atria.

The detector features multiple terminals for electrical connections, including terminals labeled T1, T2, T5, T6, T7, T8, and numbered terminals 1 through 8 with function indicators like LD (likely related to Alarm or LED indication) and WZ/LD (potentially related to Fault or Wiring supervision and Alarm status). It also includes dip switches, likely used for configuring sensitivity settings (indicated by percentages 10%, 30%, 50%, 90%) or other operational parameters.

The POLON-ALFA DOP-40R provides dependable early warning fire detection in challenging environments, integrating seamlessly into compatible fire alarm control panels.
