The ANWETECH AT-ES01 is an ATEX explosion-proof point photoelectric smoke detector designed for smoke detection in hazardous industrial areas where explosive gases or combustible dust may be present.
It is suitable for Zone 1 and Zone 2 explosive gas atmospheres containing Group IIA, IIB or IIC gases with temperature classes T1 to T6. It can also be used in Zone 21 and Zone 22 combustible dust environments.
AT-ES01 is a non-addressable, switch-type smoke detector with relay output. It provides Normally Open and Normally Closed contact outputs, allowing connection to conventional fire alarm control panels, fire alarm input modules, gas fire control panels or other compatible alarm systems.
The detector uses light-scattering photoelectric smoke detection technology and a labyrinth sensing chamber design. This structure helps improve stability, anti-condensation performance, dust resistance, ambient light immunity, humidity resistance and chemical corrosion resistance.
When smoke concentration exceeds the preset alarm threshold, the detector indicator changes from flashing red to steady red and sends an alarm signal through the relay contact output. The detector resets after a system reset or brief power interruption.

AT-ES01 uses DC24V non-polarized power input and relay contact output. The relay output allows the detector to be connected with conventional fire alarm systems, input modules or other compatible alarm control equipment.
| Terminal | Meaning |
|---|---|
| DD | DC24V power input, non-polarized |
| NO | Normally Open contact |
| COM | Common terminal |
| NC | Normally Closed contact |
The detector provides one pair of Normally Open and Normally Closed contact outputs. The final wiring method should follow the fire alarm control panel or input module wiring requirements.
