Installation of sense cable
If it is the model of WDZ3ZT, it is necessary to standardize the installation of the sense cable.
Auxiliary material
** Material| No**.
---|---
Wire nail| few
Hammer| 1
Screwdriver| 1

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.

Use of Device

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.
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.

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.
