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 famous for its long-distance transmission and low power consumption. Compared

with other communication methods, LoRa spread spectrum modulation technique greatly extend the communication distance. It

can be widely used in any use case that requires long-distance and low-data wireless communications. For example, automatic

meter reading, building automation equipment, wireless security systems, industrial monitoring. It has features like small size,

low power consumption, long transmission distance, strong 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

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 factory setting) Press and hold the function key for 5 seconds till green indicator flashes for 20 times.

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.

The device will immediately send a version packet report along with an uplink packet including reed switch status and

battery voltage.

Data will be reported by default setting before any configuration.

Default setting:

Maximum time: 3600s

Minimum time: 3600s (Detect the current voltage value every 3600s by default setting)

Battery change : 0x01 (0.1V)

R311A status:

When the R311A status changes, it will send a warning report.

Window/Door sensor open : 1

Window/Door sensor close : 0

The reported data is decoded by the Netvox LoRaWANApplication Command document and

Note:

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) 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).

(4) When installing the device, the magnet must move along the X axis relative to the sensor.

If the magnet moves along the Y axis relative to the sensor, it will cause repeated reports due to the magnetic field.

1.Tear off 3M release paper of the magnet body and attach the

body to the door frame and stick it to the door in parallel

with the door magnet body. (please do not stick it on the

rough door to avoid falling off after using the device for a

long time).

As shown in the enlarged view on the right

Note:

Wipe the door clean before installation to avoid dust on the

door and affect the adhesion of the device.

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 installation distance between the magnet body and the

magnet should be less than 2cm.

This figure shows the scene where the door magnetic sensor

(R311A) is applied to the door (opening and closing).

It can also be applied to the following scenarios:

Door, window

drawer

Machine room door

Archive room

Closet

Refrigerator and freezer

Cargo ship door

Garage Door

Places which are necessary to detect the op

ening and

closing state

2.When the door is opened, the magnetic body of the door is

separated from the magnet, and the magnetic device sends

an "alarm" message.

When the door is closed, the magnetic body of the door is

merged with the magnet, the device returns to the "normal"

state, and the status information of the off is sent.
