1 Product Description 1.1 Overview This document provides a user manual for all of the device variants in the BLE Sensor Family Gen2 developed by TEKTELIC Communications Inc that fall under the definition of “portable devices” according to the FCC. This document includes descriptions of each variant and guides regarding the HW capabilities of each variant. For the functional operation and SW behaviour of each variant, please refer to the specific TRM document for that particular sensor.
2. By mechanical enclosure and mounting combination (See Table 1-2). 3. By PCBA (see Figure 1-2, Figure 1-3, and Table 1-1). There are three “levels” of component from a production point of view, each of which has its own product code or “T-code.” All sensors share a single common PCB (one T-code). The PCBs are populated with different combinations of transducers/components to make seven different PCBAs (seven T-codes).

cycle is 100%. This represents a continuous scan over each scan duration. A larger duty cycle will increase the likelihood of receiving more beacon packets at the expense of consuming more power. The scan period, duration, interval, and window are all configurable. For all user configurable device settings, refer to the specific TRM document for that sensor).

a battery pull-tab or reset button pinhole as in the AA-cell enclosures. The reed switch therefore is included in the C-cell devices to address these purposes: 1. To wake the device from sleep (the C-cell variants are shipped in a state of deep sleep since battery pull-tabs are not available). 2. To put the device to sleep. 3. To reset the device (since the C-cell variants do not have a reset button). 4. To force an UL.
reports for a single event, depending on the definition of an event in a particular use case. An alarm event can only be registered after a configurable grace period elapses since the last registered alarm event. Carefully setting the grace period is important and prevents from repeatedly registering an accelerometer event. The accelerometer can also be polled periodically for its output acceleration vector for applications in which the sensor’s orientation is of interest.
2 Installation 2.1 Included Product and Installation Material The following items are shipped with each sensor: 1x sensor inside an enclosure with 3.6 V AA-cell or C-cell LTC battery installed. 1x corresponding sensor Quick Start Guide. 1x mounting bracket (only for variants with mounting). 1x small magnet (only for C-cell variants). 2.
3. Do not discard the shipping box or inserts as they will be required if a unit is returned for repair or re-configuration. 2.4 Commissioning and Activation Each sensor has a set of commissioning information that must be entered into the network server in order for the sensor to be able to join the network and begin normal operation once activated. For instructions on how to do this please refer to the Network Server Quick Start Guide (available online in the Knowledge Base) [4].
Once activated, the sensor will automatically begin the join process. To turn the sensor off, the battery must be removed. To reset the device, the external reset button can be pushed; see Section 3.4 for a description of the reset function. Refer to Section 3.3 for the expected LED behaviour of the Tracker during the join process. 2.5 Mounting The only mounting options for the portable sensor variants are the belt clip mount and the lanyard mount.
Figure 2-2: Using a Tool to Release the End-Cap 2. Pull the end-cap out. The end-cap is fastened to the PCBA such that the whole interior of the device will also come out. 3. Remove the battery and replace with a new one. Ensure that the polarity of the battery is in the proper orientation as shown in Figure 2-3. Figure 2-3: Battery Polarity Orientation Gen2 BLE Sensor Family User Guide TEKTELIC Communications Inc. T0007796_UG_Portable Version 0.
4. Replace the PCBA and end-cap in the same orientation as before and push firmly to shut as shown in Figure 2-4. Figure 2-4: Replacing the PCBA and End-Cap 2.6.2 Battery Replacement Procedure for C-Cell Sensor Variants The battery cover is marked with a battery symbol and uses Phillips Head H1 screws. This is the cover that needs to be removed to replace the battery, NOT the feature cover on the opposite side which is marked by a magnet symbol and uses Torx Head screws. 1.
2. Remove and the used battery, and replace it with a new 3.6V XENO XL-145F battery ONLY. When inserting the new battery, insert the negative terminal side first. The battery contacts are marked with their proper polarities (see Figure 2-6), with the positive terminal marked with a plus-sign (+), and the negative with a minus-sign (-). Figure 2-6: Battery Polarity Markers and Insertion Gen2 BLE Sensor Family User Guide TEKTELIC Communications Inc. T0007796_UG_Portable Version 0.
3. Check that the gasket is undamaged and still properly seated with an adhesive on the battery cover. It should look similar to Figure 2-7. Figure 2-7: Proper Gasket Appearance 4. Before reattaching the battery cover, ensure the proper orientation of the cover by placing the battery symbol next to the mounting feature. You can also ensure proper orientation by closing it with the semi-circular rib against the battery, and the T-shaped rib against the PCBA (see Figure 2-8).
3 Operation, Alarms, and Management 3.1 Configuration The Gen2 sensor variants support a full range of OTA configuration options. Specific technical details are available in the corresponding TRM document for each functional grouping. All configuration commands need to be sent OTA during the sensor’s DL Rx windows. 3.2 Default Configuration Table 3-1 lists the default reporting behaviour for each functional grouping of the Gen2 sensor variants.
b. If the red LoRa LED blinks, then one of the health checks failed. Consider replacing the battery, or moving the sensor to an environment within temperature range. 3. Immediately after the boot pattern, the join procedure will begin. During this time the green system LED will blink continuously until the sensor has joined a network. 4. The red LoRa LED will now blink whenever LoRa activity occurs on the sensor (transmitting or receiving packets, including the join request packets).
to the specific TRM documents for descriptions of the function button behaviour and user configurability. 3.6 Buzzer and Vibration Feedback The Contact Tracing Device and SafeAlert variants are equipped with a PCBA-mounted buzzer and vibration motor. These provide audible and haptic feedback for the user during normal operation. Refer to the specific TRM documents for descriptions of the buzzer and vibration motor behaviour and user configurability.
