Introduction

The wireless push button interface allows a notification signal to be sent when the connected push button is pushed. When someone is in danger and needs emergency assistance, press the emergency push button device; R718T immediately sends an alarm message to the gateway.

LoRa Wireless Technology:
LoRa is a wireless communication technology dedicated to long distances 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 Examples, 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.

netvox-R718T-Wireless-Push-Button-Interface-fig-2

Note: MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration regardless BtteryVoltageChange value.

Example#2 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.netvox-R718T-Wireless-Push-Button-

Example#3 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.netvox-R718T-Wireless-Push-Button-
Interface-fig-4

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.

  1. 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.

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.

Information about Battery Passivation

Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density. However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high. This lithium chloride layer prevents rapid self-discharge caused by continuous reaction between lithium and thionyl chloride, but battery passivation may also lead to voltage delay when the batteries are put into operation, and our devices may not work correctly in this situation.

As a result, please make sure to source batteries from reliable vendors, and it is suggested that if the storage period is more than one month from the date of battery production, all the batteries should be activated. If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis. ER14505 Battery Passivation:

To determine whether a battery requires activation
Connect a new ER14505 battery to a resistor in parallel, and check the voltage of the circuit. If the voltage is below 3.3V, it means the battery requires activation.

How to activate the battery

  • Connect a battery to a resistor in parallel
  • Keep the connection for 5~8 minutes
  • The voltage of the circuit should be ≧3.3, indicating successful activation.
Brand Load Resistance Activation Time Activation Current
NHTONE 165 Ω 5 minutes 20mA
RAMWAY 67 Ω 8 minutes 50mA
EVE 67 Ω 8 minutes 50mA
SAFT 67 Ω 8 minutes 50mA

Note:
If you buy batteries from other than the above four manufacturers, then the battery activation time, activation current, and required load resistance shall be mainly subject to the announcement of each manufacturer.

Important Maintenance Instruction

Kindly pay attention to the following in order to achieve the best maintenance of the product:

  • Keep the device dry. Rain, moisture, or any liquid might contain minerals and thus corrode electronic circuits. If the device gets wet, please dry it completely.
  • Do not use or store the device in dusty or dirty environment. It might damage its detachable parts and electronic components.
  • Do not store the device under excessive heat condition. High temperature can shorten the life of electronic devices, destroy batteries, and deform or melt some plastic parts.
  • Do not store the device in places that are too cold. 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. Rough handling of equipment can destroy internal circuit boards and delicate structures.
  • Do not clean the device with strong chemicals, detergents or strong detergents.
  • Do not apply the device with paint. Smudges might block in the device and affect the operation.
  • Do not throw the battery into the fire, or the battery will explode. Damaged batteries may also explode.

All of the above applies to your device, battery and accessories. If any device is not working properly, please take it to the nearest authorized service facility for repair.
