Introduction
R311CB is a switch detection device which is the Class A device of Netvox based on LoRaWAN
TM
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.
