Installation:
(1)Power on/off
- Power on: Moving magnet toward LoRa terminal center position sensor until hear the beep,
and the beep sound will automatically stop after 2 seconds that means power on, then you should remove the magnet.
- Power off: Moving magnet toward LoRa terminal center position sensor until hear the beep,
keep the magnet stay in the position, and the beep sound will automatically stop after 6 seconds that means power off, then you should remove the magnet.
Note: During switch on/off operation, you need to keep magnet stay in the position when heard the beep sound.
You can only ramove magnet until the beep stoped.
(2)Warning Beep
- The beep ringing last about 2 seconds then stop, that means Power On
- The beep ringing for 3 times, that means Network Access
- The beep ringing last about 6 seconds then stop, that means Power Off
(3)Installation Procedure
- Firstly, open the manhole cover, keep the surface of product toward the gateway direction; keep the position switch upward
- Secondly, find 4 corresponding points in the wall, then marked and punched
- Finally, pin the monitor and alarm machine to the wall by screws
Note:
1.During installation, the part of monitor and alarm need to be set at the opposite of gateway;
the spring of position switch can not beyond the top of well, in case of the manhole cover crush it that will cause a sensor failure.
2.When installing the manhole cover, please handle with care to avoid it damage the sensor.
