1. Product Introduction
1.1 Overview
GS101 is a LoRaWAN®residential gas detector to detect the natural gas leak and send alarms.
When the concentration caused by gas leak reaches the preset threshold, the detector will
trigger LED light alarm and buzzer sound alarm, it also supports controlling outputs to close the
gas valve and open the vent fans to prevent potential accidents.
Apart from local alarms, GS101 can also report the normal status of the device and alarm
messages remotely by the use of LoRaWAN®technology. Integrating with Milesight LoRaWAN®
gateway and Milesight IoT Cloud solution, users can monitor all the sensor data and control the
device remotely and visually.

Wiring Diagram
The relay output can connect the device up to 250VAC/10A, and the solenoid valve output is a
12V/100ms pulse output. When the alarm is triggered, the relay output will open the fan and
solenoid valve output will send a pulse to close the valve; when the alarm is dismissed, the relay
output will close the fan, and the valve status will not change. You can open the solenoid valve
manually or via send downlink commands.

3. Operation Guide
3.1 Basic Configuration
1. Connect the outputs to the solenoid valve, fan or other devices.
2. Power on the detector via default power adapter and wait for about 180s for the warm-up
process. When the warm-up finishes, the buzzer will beep twice and all indicators will stop
blinking except for the Power indicator.
3. Press the Test button to check if the LED indicators and buzzer work properly, if the relay
output can open the fan and valve output can close the gas valve. After testing, everything will
