1. Introduction
The R313CA is a dry contact detection device for Netvox ClassAtype devices based on the LoRaWAN open protocol and is
compatible with LoRaWAN protocol. When any dry contact of R313CA detects a change, R313CA will send a message to the
gateway.
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 need a flat blade screwdriver to open)
Turn on
The device (unjoin the network) is power off according to default when the battery is installed.
Currently, press any button of the device shortly. After release, the red and green indicators will
flash one time simultaneously that means the device turns on successfully.
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 reinsert the battery: according to the default, the device is in a turn off state.
2. After 5 seconds of powering on, the device is in engineering testing mode.
3. In the turn-on state, the interval of remove and reinsert the battery is suggested to be about 10
seconds. After reinserted the battery, the device is in the turn-on state according to the default.
(If
the device has been turned on, it does not need to press the button to enter the turn-on state.) The
red and green indicators will flash one time simultaneously.
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
The green indicator flashes 20 times: success
The green indicator remains off: fail
Press once The device is in the network: the green indicator flashes once and sends a report
The device is not in the network: the green indicator remains off

Sleeping Mode
The device is turn on
and join
in the network
Sleeping period: Min Interval.
When the reportchange exceeds the default or the state of the device changes: send a data report
according to Min Interval.
Low Voltage Warning
Low Voltage 2.4V
*Suggest removing batteries if the device is not used to save power.
5. Data Report
After power on, the device will immediately send a version packet report and a data report including temperature, humidity,
and voltage.
The device sends data according to the default configuration before any other configuring.
Report MaxTime：Max Interval ----3600s
Report MinTime：Min Interval ----3600s (Default: Every Min Interval will detect the state of the dry contact one time)
Default reportchange: BatteryVoltageChange ---- 0x01(0.1V)
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.
Triggering the dry contact:
When the dry contact detects the state changing, the report will be sent immediately.

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:

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 dry contact sensor (R313CA) can be applied to the
following scenes:
Various switches and buttons
The output of the dry contact of the sensor
The operating state of the device
Monitoring the condition of doors and windows in home
or in business
2.When the device detects the state of dry contact changing,
the data report will be sent immediately.
3.If detect the battery voltage exceeding the value of the
variation at MinTime, the report will be sent immediately.
4.No matter the state of the dry contact changes, the data
report must be sent at MaxTime.
Note:
When the dry contact is close, the state of the data is “0”.
When the dry contact is open, the state of that is “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.
