6.4.2.installation steps
Plan the installation and routing position of the sense cable before
installation.
The two ends of the sense cable have their own interface plugs, and the
plugs can be connected with the plugs connected to the sensors.
The part of the sense cable is fixedly installed according to the planned
line, and it is neat and tidy.
Note:
Any one of the sense cable will trigger an alarm.
The two black wires of the cable are conductive adhesives. If the
resistance between the black wires is less than 50MΩ, the alarm will be
triggered regardless of whether the wire is stripped.
During the installation or post-maintenance process, if you need to
re-wire the wiring.
Avoid the two black wires to be contact too close.

7. Use of Device
7.1. Power on
Place the device within the coverage of the ZETA network, install the
battery, and wait for the device to go online. After the device is online, the
current sensor status is reported once.

7.2. Support function
Report/Query version number: After the power is turned on, the
version number information is reported by default. After that, the
query can be sent.
Status report: Reports the heartbeat/alarm/de-alarm status, and
reports a heartbeat status after power-on.
Set/Query the alarm report period: The time when the sensor detects
the periodic report when it is flooded (range: 0-255 minutes, default
value: 0, 0 means the alarm is only reported once, no periodic report is
required.)
Set/Query Report Heartbeat Period: You can set or query the currently
set heartbeat reporting period by minute. (Range: 1~65535 min,
default: 24*60 min)
Set/Query Alarm Enable: Enable ON means that the alarm status needs
to be reported when the threshold is exceeded. Enable Off means no
alarm is required even if the threshold is exceeded.
Set/Query Acquisition Period: The period during which the device
collects sensor information (range: 0-65535 seconds, when the value is
0, it means real-time acquisition, default value: 5s).
Query device status: Actively query the current status of the device,
including whether it is flooded, and alarm enable information.
8. Common faults and handling
Ensure ZETA signal coverage
Ensure that the device is powered on, and the ZETA network device
management platform can observe that the ZETA module is on line
Check the battery usage of the device. When the battery is low, replace
the battery in time.
