1.4 Alarm Info
The SMG-C analog gateway is equipped with two indicators denoting the system’s running status:
Run Indicator (green LED) and Alarm Indicator (red LED). The table below explains the states and
meanings of the two indicators.

Note:
The startup process consists of two stages: System Booting and Gateway Service
Startup. The system booting costs about 1 minute and once it succeeds, both the run
indicator and the alarm indicator light up. Then after the gateway service is successfully
started and the device begins to work normally, the run indicator flashes and the alarm
indicator goes out.
During runtime, if the alarm indicator lights up or flashes, it indicates that the device goes
abnormal. If you cannot figure out and solve the problem by yourself, please contact our
technicians for help. Go to
