Explosion-proof, reflective linear infrared beam smoke detector
for Zone 1 and Zone 2 hazardous areas (Gas Groups IIA, IIB, IIC; T1–T6).
Ex marking: Ex db ib IIC T6 Gb / Ex tb IIIC T80°C Db.
Beam length up to 100 m, coverage up to 1,400 m² (100 m × 14 m).
Overview
The AT-EB01 Explosion-Proof Infrared Beam Smoke Detector is a reliable solution for fire detection in hazardous areas such as Zone 1 and Zone 2 where explosive gas atmospheres may be present. Certified with Ex db ib IIC T6 Gb / Ex tb IIIC T80 °C Db, this explosion-proof beam smoke detector is designed to operate safely in environments with gas groups IIA, IIB, and IIC.
It uses a reflective infrared beam to monitor large open spaces such as oil and gas plants, chemical processing units, and warehouses with high ceilings.
Key Features
Explosion-proof design compliant with GB3836 and certified for Zone 1 & Zone 2 hazardous areas.
Infrared reflective beam technology with a detection range up to 100 m and maximum coverage of 1,400 m² (100 m × 14 m).
Works with either 1 or 4 reflectors, depending on installation distance.
Two module types available:non-coded (conventional) for DC 24 V powered systems.
Wide operating conditions: –20 °C to +50 °C, ≤ 95 % RH, suitable for harsh industrial site
Typical Applications
The AT-EB01 explosion-proof infrared beam smoke detector is designed for Zone 1 and Zone 2 hazardous areas with explosive gas atmospheres, especially in:
Oil & gas processing plants, refineries, LNG terminals
Chemical production and solvent storage warehouses
Paint, coating and fuel handling facilities
Large industrial halls with combustible gas environments
Other hazardous area sites requiring Ex db IIC T6 certified beam-type smoke detection
