1. Introduction
R311CB is a switch detection device which is the ClassAdevice of Netvox based on LoRaWANTM protocol.
It is compatible with the LoRaWAN protocol. When the doors and windows are abnormally opened or the glass of the doors and
windows are broken, R311CB will send a message to the gateway.
It can be installed on the door or window with two glass sliding sashes. The reed switch and the magnet of the main body are
respectively installed on both sides of the window sashes. The external reed switch and the magnet can be installed on both sides
of another window sashes, and the glass sensor can be pasted on the glass.
When the window or door is opened, R311CB will send an alarm message to the gateway. When the door or window is closed, it
will send a message that the state is normal. When the glass is broken, R311CB will send an alarm message to the gateway, and
then the data which is sent after breakage is based on the current state. If it is open, the data is an alarm state. If it is closed, the data
is a normal state.
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 and 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. (users may need a flat blade screwdriver to open);
Insert two sections of 3V CR2450 button batteries and close the battery cover.)
Turn on Press any function key till green and red indicator flashes once.
Turn off
(Restore to original setting)
Press simultaneously and hold two function keys for 5 seconds, and then the green indicator will
flash continuously. After release function keys, the green indicator flashes 20 times and the device
will turn off automatically.
Power off Remove Batteries
Note:
1. Remove and insert the battery; the device memorizes previous on/off state by default.
2. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor
inductance and other energy storage components.
3. Press any function key and insert batteries at the same time; it will enter engineer testing mode.
Network Joining
Never join the network
Turn on the device to search the network to join.
The green indicator stays on for 5 seconds: success
The green indicator remains off: fail
Had joined the network
(Not in the original setting)
Turn on the device to search the previous network to join.
The green indicator stays on for 5 seconds: success
The green indicator remains off: fail
Fail to join the network Suggest checking device verification on gateway or consulting your platform server provider if the
device fails to join the network.
Function Key
Press and hold for 5 seconds
Restore to the original setting / Turn off

Low Voltage 2.4V
5. Data Report
After power on, the device will immediately send a version packet report and a data report including reed switch status, glass
break status and voltage.
The device sends data according to the default configuration before any other configuring.
Default setting:
Report MaxTime: 1H (3600s)
Report MinTime: 1H (3600s)
BatteryVoltageChange：0x01 (0.1V)
Triggering the reed switch:
When the reed switch detects the state changing, the report will be sent immediately.
The report (status1): Open: on; Close: off
* The main body and the external sensor share an I/O status1;
therefore, when either the main body or the external sensor is in the open state, the report status will be 1.
The report status will be 0 only when both the main body and the external sensor are closed.
Triggering the glass sensor:
When the glass breakage detector is triggered, the status2 is on.
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.
The device reported data parsing please refer to Netvox LoraWAN Application Command document and Netvox Lora
Command Resolver http://loraresolver.netvoxcloud.com:8888/page/index
Data report configuration and sending period are as following：

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. Remove the 3M release paper on the back of the device and
attach the device to the smooth wall (please do not stick it to
the rough wall to avoid falling off after a longtime usage).
Note:
The distance between the magnet and the reed switch must
be less than 2cm.
Wipe the wall surface before installation to avoid dust on
the wall surface that affect the effect of the paste.
Do not install the device in a metal shielded box or other
electrical equipment around it to avoid affecting the
wireless transmission of the device.
The sensor (R311CB) can be applied to the following scenes:
Office building
School
Shopping mall
Villa
The occasions with glass windows or glass doors.
2. If R311CB with the glass sensor detects that the window is
opened (the magnet is separated from the main body) or
closed (the magnet and the main body are closed), the data
will be sent immediately.
3. If the glass breaking vibration triggers the glass sensor, the
data will be sent immediately.
4.If it detects the battery voltage exceeding the variation value
at MinTime, the data will be sent immediately.
5.Even if the window status does not change or the no broken
glass is detected, the data will be sent regularly according to
the Max Time.
Note:
when either the main body or the external sensor is in the
open state, the report status1 will be 1.
The report status1 will be 0 only when both the main body
and the external sensor are closed.
When the glass break detector is triggered,
the report status2 will be 1.

7. Important Maintenance Instruction
The device is a product with superior design and craftsmanship and should be used with care.
The following suggestions will help you use the warranty service effectively.
• 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.
