Safety Tips
Installation points
The host should be avoided from being installed inside a metal cabinet to prevent signal shielding
GSM antenna needs to be placed vertically to optimize signal strength
Maintenance suggestions
Monthly testing of backup batteries (with a typical range of 72 hours)
Regularly clean the sensor contacts to prevent oxidation from causing false alarms
Fault handling
Frequent false alarms: Check the sensor battery voltage (replace if it is below 2.8V)
APP offline: prioritize restarting the router over the host
