Configuration Examples

LoRa Channel Settings
The configuration of LoRaWAN® channel of EM300 must match the gateway’s. Refer to Appendix to check default channel settings of EM300.

Mobile APP Configuration:
Open Toolbox APP and go to “Device ->Setting -> LoRaWAN Settings” to change the frequency and channels.

Software Configuration:
Log in Toolbox and go to “LoRaWAN Settings -> Channel” to change frequency and channels.
Note: If frequency is one of CN470/AU915/US915, you can enter the index of the channel that you want to enable in the input box, making them separated by commas.
Examples:
1, 40: Enabling Channel 1 and Channel 40
1-40: Enabling Channel 1 to Channel 40
1-40, 60: Enabling Channel 1 to Channel 40 and Channel 60 All: Enabling all channels
Null: Indicates that all channels are disabled

Alarm Settings
When water leakage sensor or magnet switch sensor is triggered, it will send alarm message once by default. Toolbox allows users to change the alarm reporting interval and reporting times.

Mobile APP Configuration:
Open Toolbox APP and go to “Device -> Setting -> Threshold Settings” to enable the threshold settings and input the threshold.

Software Configuration:
Log in Toolbox and go to “Device Settings -> Basic -> Threshold Settings” to enable the calibration and input the calibration value.

Installation

1. Attach EM300 to the wall and mark the two holes on the wall. The connecting line of two holes must be a horizontal line.
2. Drill the holes according to the marks and screw the wall plugs into the wall.
3. Mount the EM300 to the wall via mounting screws.
4. Cover the mounting screws with screw caps.
   
5. For leak detection senor, install the probe/cable to the place where liquid may leak. For magnet switch sensor, install the magnet beside the door/window.

Note: For SLD sensor, please ensure the metal pins of the probe are flat on the floor; for ZLD sensor, the cable can’t be twined or accumulated together. The probe or cable of water leakage sensor should be placed in an area of concern where water from a leak would likely accumulate.
