1.Introduction
RB02B, a wireless push button, is a long-distance trigger device which is the ClassAdevice of Netvox based on the LoRaWANTM
protocol.
The device has two trigger buttons. According to the requirement of different applications, press the trigger button of RB02B, and the
device will immediately send the trigger information to the gateway. RB02B is compatible with the LoRaWAN protocol.
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. (Users may need a screwdriver to open the cover.)
Turn on Press the function key once and the indicator flashes once meaning turning on successfully.
Turn off (Restore to original setting) Press and hold the function key for 5 seconds and the green indicator flashes 20 times.
Power off Remove Batteries.
Note
1. Remove and insert the battery; the device is at 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. After insert batteries and press any button, the device will be in engineering test mode.
Network Joining
Never joined 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

5.Data Report
After power on, the device will immediately send a version packet report and a data report including the voltage.
The device sends data according to the default configuration before any other configuring.
Default setting:
Report MaxTime: 3600s (1H)
Report MinTime: 3600s (1H)
Battery Voltage Change: 0x01 (0.1V)
(If there are special customized shipments, the settings will be changed according to customer’s requirement.)
Status change
:
Press: Report: 1.
Not pressed: Report: 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.
The data parsing that is reported by the device please refer to Netvox LoraWAN Application Command document and
Netvox Lora Command Resolver http://loraresolver.netvoxcloud.com:8888/page/index
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 data collected is compared with the last data reported. If the data change value is greater than the ReportableChange value,
the device reports according to MinTime interval. If the data variation is not greater than the last data reported, the device
reports according to MaxTime interval.
3)We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is too low, the device wakes up
frequently and the battery will be drained soon.
4) Whenever the device sends a report, no matter resulting from data variation, button pushed or MaxTime interval, another cycle
of MinTime / MaxTime calculation is started.

6.Installation
1. Use the attached 3M rubber pad, stick one side to the Wireless 2-
Gang Push Button (RB02B), and stick the other side to the wall.
2. To make the installation firmer, please use screws (purchased
separately) to fix the device to the wall.
* Note:
Please don't stick it on the rough wall to avoid the device from
falling off after the long-term usage.
If use the supplied 3M rubber pad, please wipe the wall clean before
installation to avoid dust on the wall and affect the effect of the
paste.
The middle part of the 3M rubber pad (the part with the red frame in
the figure below) is where the label is attached to the device. Please
remove the rubber pad that has been cut.
Do not install the device in a metal shielded box or in an
environment surrounded by other electrical equipment to avoid
affecting the wireless transmission of the device.
3.Install the battery in the battery holder, and close the
snap-fit joint of the device.
*Note:
If user wants to open the snap-fit joint, user can pry it
gently.
RB02B can be applied to the following scenarios:
Home (bathroom)
School
Nursing home
Hospital
Bank
Hotel
The place where an emergency may occur.

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.
