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 which fall under the definition of “mobile devices” as defined by 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.
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).

The BLE scan can be disabled entirely or enabled at any time. Figure 1-5 shows the BLE scan scheme when the BLE scan is enabled. As shown in the figure, BLE scans are performed periodically. Each scan duration is divided into scan intervals. The BLE scan is performed only in the scan window portion of the scan interval. The ratio of the scan window to the scan interval is the scan duty cycle. In the case of the scan window equalling the scan interval, the scan duty cycle is 100%.
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. The position on the exterior of the enclosure on which the magnet must be placed to activate the reed switch is shown in Figure 1-4. For more information on how to wake the device from sleep, refer to Section 2.4.
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 1. The mounting bracket needs to be secured to a wall or another solid surface by using an adhesive, or four mounting screws (see Figure 2-2).
Figure 2-3: Attaching the Sensor to the Mounting Bracket 3. Using a fifth screw inserted through both holes on the top side of the bracket as shown in Figure 2-4, clamp the top flange of the bracket until it is flush with the top surface of the sensor. Figure 2-4: Securing the Sensor in the Mounting Bracket with a Fifth Screw Gen2 BLE Sensor Family User Guide TEKTELIC Communications Inc. T0006940_UG_Mobile Version 1.
2.6 Battery Replacement 2.6.1 Battery Replacement Procedure for AA-Cell Sensor Variants 1. There are case-release slots in the front and back of the enclosure near the bottom endcap. Using pliers or a similar tool, press on each of the case-release tabs until the lips clear the edge and the end-cap is free as shown in Figure 2-5. Figure 2-5: 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.
Figure 2-6: Battery Polarity Orientation 4. Replace the PCBA and end-cap in the same orientation as before and push firmly to shut as shown in Figure 2-7. Figure 2-7: 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.
1. In a non-hazardous location, remove the battery cover by unscrewing the 4x phillips head screws using a size #1 phillips head screwdriver as shown in Figure 2-8. Figure 2-8: Removing the Battery Cover Screws 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.
Figure 2-9: Battery Polarity Markers and Insertion 3. Check that the gasket is undamaged and still properly seated with an adhesive on the battery cover. It should look similar to Figure 2-10. Figure 2-10: 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.
Figure 2-11: Proper Replacement Orientation of the Battery Cover 5. Reassemble the cover to the chassis by using the 4x phillips head screws, using a #1 size screwdriver and up to 0.23 Nm of torque. Gen2 BLE Sensor Family User Guide TEKTELIC Communications Inc. T0006940_UG_Mobile Version 1.
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).
