When it is sleeping, it does not collect data. 2) The data collected is compared with the last data reported. If the data variation 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. 7 6. Installation 1. R718F has a built-in magnet (as the figure below). When installed, it can be attached to the surface of an object with iron which is convenient and quick. To make the installation more secure, use screws (purchased separately) to secure the unit to a wall or other surface (as the figure below). Note: Do not install the device in a metal shielded box or in an environment with other electrical equipment around it to avoid affecting the wireless transmission of the device. 2. When the door or window is opened, the reed switch probe is separated from the magnet, and the device sends an alarm message about the opening. When the door or window is closed, the reed switch probe and the magnet get closer, and the device restores to the normal state and sends a state message about the closing. R718F is suitable below scenarios: Door, window Machine room door Archives Closet Refrigerators and freezers Cargo ship hatch Garage door Public toilet door The place needs to detect the opening and closing status. 2. Tear off the 3M glue at the bottom of the reed switch probe and the magnet (as the red frame in the figure above). Then, stick the reed switch probe to the door and is parallel to the magnet (as the figure on the right). Note: The installation distance between the reed switch probe and the magnet should be less than 2cm. 8 Reed Switch Magnet 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. Note: Please do not disassemble the device unless it is required to replace the batteries. Do not touch the waterproof gasket, LED indicator light, function keys when replacing the batteries. Please use suitable screwdriver to tighten the screws (if using an electric screwdriver, it is recommended to set the torque as 4kgf) to ensure the device is impermeable. 9 7. 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 the batteries should be produced within the last three months. If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis. 7.1 To determine whether a battery requires activation Connect a new ER14505 battery to a 68ohm resistor in parallel, and check the voltage of the circuit. If the voltage is below 3.3V, it means the battery requires activation. 7.2 How to activate the battery a. Connect a battery to a 68ohm resistor in parallel b. Keep the connection for 6~8 minutes c. The voltage of the circuit should be 3.3V 10 8. Important Maintenance Instruction The device is a product with superior design and craftsmanship and should be used with care.
