When it is sleeping, it does not collect data. 8 (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. 9 6. Installation This device has a waterproof function. When the device is used, the back of it can be attached to the iron surface, or two ends of it can be secured on the wall by screws. When the magnet is close to or far away, the sensor will be triggered to send a report. The gap between the Hall sensor and the magnet should be less than 3cm during installation. When the installation clearance is greater than 3cm, the device will not be able to trigger the signal. 1. The Wireless 2-gang Hall Type Open/Close Detection Sensor (R718LB2) has a built-in magnet (see Figure 1 below). It can be attached to the surface with iron material during installation. To make the installation more secure, please use screws (purchased separately) to fix the device on the wall or other objects (see Figure 2 below). 2. Tear off 3M release paper of Hall sensor and the magnet then attach to the door or window in parallel. Note: The mounting distance between the Hall sensor and the magnet should be less than 3cm. Comment: 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. When the door or window is opened, the Hall sensor is separated from the magnet, and the Hall sensor sends status "1". Figure 1 Figure 1 When the door or window is closed, the Hall sensor is close to the magnet, and the Hall sensor device sends status "0". Figure 2 10 The Wireless 2-gang Hall Type Open/Close Detection Sensor (R718LB2) can be used in the following scenarios: Door, window Machine room door Archives Closet Refrigerators and freezers Cargo ship door Garage Door Public toilet door Where you need to detect the opening and closing status. When installing the device, the magnet must move along the X axis relative to the sensor. 11 If the magnet moves along the Y axis relative to the sensor, it will cause repeated reports due to the magnetic field. 12 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 13 8. Important Maintenance Instruction Kindly pay attention to the following in order to achieve the best maintenance of the product: · Keep the device dry.
