1. Introduction
R311A is a long-distance window/door sensor based on the LoRaWAN open protocol (Class A).
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.
This device has been certified by the LoRa Alliance and is allowed to use the following logo on the
product:

4.Set up Instruction
4.1 Power on and Turn on / off
(1) Power on = Insert batteries: open the battery cover (users may need a flat blade screwdriver to
open); insert two sections of 3V CR2450 button batteries and close the battery cover.
(2) Turn on. If the device had never joined in any network or at factory setting mode, after powering
on, the device is at off mode by default setting. Press function key and release to turn on the device.
The green and red indicator will flash once to show that R311A is turned on.
(3) Turn off. Press and hold function key for 5 seconds till the green indicator flashes quickly and
release. The green indicator will flash 20 times to show that R311A is turned off.
(4) Remove batteries (power off) when R311A is on. Wait till 10 seconds after the capacitance
discharging. Insert batteries again, R311A will be setted to be on mode by default. There is not need
to press function key to turn on the device. The red and green indicators will both flash and then
light off.
Note:
1. The interval between turning on/off or powering off/on is suggested to be about 10 seconds to
avoid the interference of capacitor inductance and other energy storage components.
2. Do not press function key and insert batteries in the same time, otherwise, it will enter engineer
testing mode.
4.2 Join Into Lora Network
To join R311A into LoRa network to communicate with LoRa gateway.
The network operation is as following:
(1) If R311A had never joined any network or at factory setting mode, turn on the device; it will
search an available LoRa network to join. The green indicator will stay on for 5 seconds to show it
joins into the network, otherwise, the green indicator does not work.
(2) If R311A had been joined into a LoRa network, remove and insert the batteries; the green
indicator will stay on for 5 seconds to show it joins into the network.
4.3 Function Key
(1) Press and hold function key for 5 seconds to reset to factory setting. After restoring to
factory setting successfully, the green indicator will flashes quickly 20 times.
(2) Press function key; the green indicator will flash once and the device will send a data report.
4.4 Data Report
When the device is turned on, it will immediately send a version package.
The transmission frequency of sending version package is once every 24 hours.
Data will be reported once per hour by default setting.

Maximum time: 3600s
Minimum time: 3600s (Detect the current voltage value every 3600s by default setting)
Default reportchange:
Battery ---- 0x01 (0.1V)
R311A sensor is triggered:
When the R311A status changes, it will send warning report.
Window/Door sensor open:1
Window/Door sensor close:0
Note: MinInterval is the sampling period for the Sensor. Sampling period >= MinInterval.
Data report configuration and sending period are as following:
5. Restore to Factory Setting
R311A saves data including network key information, configuration information, etc. To restore to
factory setting, users need to execute below operations.
1. Press and hold function key for 5 seconds till the green indicator flashes and then release; LED
flashes quickly 20 times.
2. R311A will be turned off mode after restoring to factory setting.
6. Sleeping Mode
R311A is designed to enter sleeping mode for power-saving in some situations:
(A) While the device is in the network → the sleeping period is one hour. (During this period,
if the reportchange is larger than setting value, it will wake up and send a data report).
(B) When it is not in the network → R311A will enter sleeping mode and wake up every 15
seconds to search a network to join in the first two minutes. After two minutes, it will wake up
every 15 minutes to request to join the network.
If it’s at (B) status, to prevent this unwanted power consumption, we recommend that users

remove the batteries to power off the device.
7. Low Voltage Alarming
The operating voltage threshold is 2.4V. If the voltage is lower than 2.4V, R311A will send a
low-power report to the Lora network.

9. Installation
(1) This product does not have a waterproof function. After the screening is completed, please place
it indoors.
(2) The door magnetic magnet part and the body part are installed on both sides of the door joint or
the window joint, and the distance between the two needs to be less than 2cm; the dust in the
installation position of the equipment needs to be wiped clean and then affixed to the equipment.
(3) The battery installation method is shown in the figure below (battery with "+" facing outward).
