AT-S235 LoRaWAN Wireless Smoke Detector

Wireless fire detection, made easier.

The ANWETECH AT-S235 is a battery-powered LoRaWAN® photoelectric smoke detector for wireless fire monitoring in indoor spaces. It pairs a local audible-and-visual alarm with LoRaWAN wireless reporting, sending smoke, high-temperature, and low-battery events through a compatible gateway to a network server or monitoring platform. Because no signal or power wiring is required, it is well suited to retrofit projects, existing buildings, and distributed sites where conventional cabling is difficult or undesirable. INDUS-MEDICA supplies and installs the AT-S235 as part of our fire protection solutions.

Features

Why Go Wireless

  • Wireless LoRaWAN

    Sends alarm and device-status data to a compatible gateway.

  • Photoelectric Sensing

    Early detection of smoke from developing fire conditions.

  • Local + Remote Alarm

    Built-in LED and ≥80 dB buzzer, plus remote reporting.

  • No Signal Wiring

    Ideal for retrofits and existing buildings.

  • High-Temperature Alarm

    Reports when the temperature threshold is exceeded.

  • Low-Battery Monitoring

    Automatic low-voltage warning for preventive maintenance.

  • 3-Year Battery Life

    One CR17450 battery with low-power operation.

  • Self-Test & Silence

    One-button routine testing and temporary alarm silence.

How It Works

Detect Locally, Monitor Remotely

The AT-S235 connects smoke detection to your LoRaWAN network — from the detector to the gateway to platform visibility.

  • 1

    Detect

    The AT-S235 senses smoke, high temperature, or low battery and sounds a local alarm.

  • 2

    Transmit

    The event is sent over LoRaWAN wireless to a compatible gateway.

  • 3

    Cloud / Server

    The gateway forwards the data to a network server or cloud platform.

  • 4

    Monitor

    View live status and alarms on a PC web portal or mobile app.
