Asenware AW-EXTC-HW Exproof Infrared Beam Smoke Detector

AW-EXTC-HW is an exproof-housed infrared beam-type smoke detector manufactured for explosive atmosphere conditions; rather than taking a point-type sample, it evaluates smoke density in the volume extending along the beam line. It follows conventional architecture, meaning it is connected to the zone line of a classic fire detection panel rather than to an addressed loop. The manufacturer provides the explosive atmosphere statement for this model within the GB 3836-2000 series scope and uses Zone 1 and Zone 2, IIA-IIB-IIC, T1~T6 notation; since there is no EN 54 section or ATEX/IECEx statement on the product page, this product should not be evaluated with such conformity claims. As application areas, paint booths, chemical storage, and fuel filling volumes where point-type detectors become ineffective due to dust, vapor, or ceiling height stand out. The most critical detail in installation is ensuring the optical path remains permanently clear and the device is fixed to a solid, vibration-free surface; any misalignment directly affects detection.
