1. Introduction
R311K is a long-distance tilt detection device which is a Class A device based on the LoRaWAN open protocol of Netvox and is
compatible with LoRaWAN protocol. The device is a title detection sensor. When the device is tilted greater than or equal to 45
degrees in any direction, it will send a tipping signal.
LoRa Wireless Technology:
LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other
communication methods, LoRa spread spectrum modulation method greatly increases to expand the communication distance.
Widely used in long-distance, low-data wireless communications. For example, automatic meter reading, building automation
equipment, wireless security systems, industrial monitoring. Main features include small size, low power consumption,
transmission distance, anti-interference ability and so on.
LoRaWAN:
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and
gateways from different manufacturers.

4. Set up Instruction
On/Off
Power on
Insert batteries (user may need a screwdriver to open)
Insert 2 x 3V CR2450 button batteries into the battery slot in the correct direction
and close the back
cover.
Note: Require 2 button batteries to supply power at the same time.
Turn on Press and hold the function key till the green and red indicator flashes once.
Turn off
(Restore to original setting)
Press simultaneously and hold two buttons for 5 seconds, and then the green indicator flashes 20
times and the device will turn off automatically.
Power off Remove Batteries
Note:
1. Remove and reinsert the battery: the device will remember the previous on/off status by default.
2. After insert batteries and press the button at the same time, the device will be in engineering
testing mode.
3. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor
inductance and other energy storage components.

5. Data Report
After power on, the device will immediately send a version packet report and an attributes report.
The device sends data according to the default configuration before any other configuring.
Default setting:
Report MaxTime：Max Interval ----3600s
Report MinTime：Min Interval ----3600s (Default: Every Min Interval will detect the state of the dry contact one time)
BatteryVoltageChange ---- 0x01(0.1V)
Triggering the tilt detection:
The device adopts 45° tilt detection around the entire circumference. The initial state of the device is vertical placement.
When the tilt angle (any direction) changes more than 45° (45°~180°), an tipping alarm will be issued immediately.
Device Tilt: 1, Device Recovery: 0
Note:
1. The cycle of the device sending the data report is according to the default.
2. The interval between two reports must be the MinTime.
3. R311K defaults Max Interval = 60min, Min Interval = 60min
(If there are special customized shipments, the settings will be changed according to customer’s requirement.)

Notes:
(1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not
collect data.
(2) The collected data is compared with the last reported data. If the variation of the data is greater than the value of
ReportableChange, the device will report according to MinTime interval. If the data variation is not greater than the last
reported data, the device will report according to MaxTime interval.
(3) We do not recommend setting the MinTime Interval value too low. If the MinTime Interval is too low, the device will wake
up frequently and the battery will be drained soon.
(4) When the device sends a report, no matter the data changes, button is pushed or MaxTime interval comes, another cycle of
MinTime / MaxTime calculation starts.
6. Installation
(1) The device does not have a waterproof function. After the configuration of joining the network is completed,
please place it indoors.
(2) The dust at the installation location should be wiped clean before paste the device.
(3) The battery installation method is as the figure below. (the battery with the "+" side facing up)
Note: The user may need a screwdriver to open the cover.

7. Important Maintenance Instruction
Kindly pay attention to the following in order to achieve the best maintenance of the product:
• Keep the equipment dry. Rain, moisture and various liquids or water may contain minerals that can corrode
electronic circuits. In case the device is wet, please dry it completely.
• Do not use or store in dusty or dirty areas. This way can damage its detachable parts and electronic components.
• Do not store in excessive heat place. High temperatures can shorten the life of electronic devices, destroy batteries,
and deform or melt some plastic parts.
• Do not store in excessive cold place. Otherwise, when the temperature rises to normal temperature, moisture will form
inside which will destroy the board.
• Do not throw, knock or shake the device. Treating equipment roughly can destroy internal circuit boards
and delicate structures.
• Do not wash with strong chemicals, detergents or strong detergents.
• Do not paint the device. Smudges can make debris block detachable parts up and affect normal operation.
• Do not throw the battery into the fire to prevent the battery from exploding. Damaged batteries may also explode.
All the above suggestions apply equally to your device, batteries and accessories.
If any device is not operating properly.
Please take it to the nearest authorized service facility for repairing.
