Warning Hazard of Electric Shock: Battery terminals and leads are not power-limited. Short circuits can cause a fire or an explosion. Use extreme caution while connecting or disconnecting standby batteries. Electrostatic Discharge Required: Always discharge static electricity from your person by touching metal prior to handling any hardware. Failure to do so may result in damage to devices. Issue The panel displays a Low Battery Voltage (With Charger Trouble) condition. This is accompanied by General Trouble and Power Trouble LEDs being ON. Product Line ESMI Fire Detection. Environment FFSULH1001. FFSULH1002. FFSULH1003. Cause Possible causes of this issue include: Battery impedance exceeds acceptable limits This can occur after several years of use as batteries degrade. Mixing different battery brands or using batteries of the same brand but with different ages (e.g., one new and one old) can also cause this issue. Faulty power supply If the power supply is malfunctioning, it may not charge the batteries correctly, triggering the fault. Resolution Step 1: Replace the existing batteries with a new set from the same brand. This often resolves the issue if battery impedance was the root cause. Step 2: If the issue persists after replacing the batteries, the power supply may be faulty. In this case, replace the power supply unit. After replacing either the batteries or the power supply, the panel should return to normal operation.

  Issue When viewing the Modbus property in EcoStruxure Building Operation, the status displays "Attention". Product Line EcoStruxure Building Operation Environment Building Operation Automation Server Building Operation Enterprise Server Cause The "Attention" status is not documented in the Web Help, which can make it unclear what is causing this state. This status typically indicates that there is an issue occurring within the Modbus system. One common cause is an unrealistic poll rate set on a Modbus group. . Resolution If the poll rate on a Modbus group is set too fast for the server to handle—especially in large Modbus networks—this can trigger the "Attention" state. Recommended Action: Review the poll rate configured for the Modbus group. If it is set to a very low value (e.g., 1 second), increase it to a more realistic interval. For busy networks, a poll rate of 5 seconds or more is typically more achievable. Once the poll rate is adjusted to a manageable value, the Modbus status should return to "Online".

Warning Hazard of Electric Shock: Remove all power from all devices before removing any covers or doors of the system. Disconnect power at the device and at the power source. Electrostatic Discharge Required: Always discharge static electricity from your person by touching metal prior to handling any hardware. Failure to do so may result in damage to devices. Caution While removing gateway cover: Open the gateway screws and delicately remove the top cover. Take extra care during this step, as the top cover is connected to the antenna cable via a thin wire. After opening the top cover, you will be able to see the top view of the board, please insert the active SIM card in the designated slot. Once the Sim Card is properly inserted, fix the screws back and ensure that the 4G&Wi-Fi Antenna is attached properly. If the antenna cable remains disconnected from the board, then the GSM will not work.   Issue If the flex server is not able to connect to the internet via the SIM card, Ethernet, or Wi-Fi, or is in a hanged state, a phone be used by the Flex server/Gateway for troubleshooting connectivity.

Go back to Settings > Network & internet > Hotspot & tethering on the phone and turn OFF the "USB tethering" switch. Alternatively, unplug the USB cable from the phone or Flex server/Gateway. Part 3: USB Tethering with an iPhone Video link for Demo (The exact wording of menus might vary slightly depending on your iOS version.) Connect Your iPhone to Your Flex server/Gateway: Plug one end of the Lightning (or USB-C on newer iPhones) cable into the iPhone. Plug the other end of the USB cable into an available USB port on your Flex server/Gateway. Note: there are 2 USB ports in the Flex Server/Gateway you can connect to either port to establish USB Tethering. The Flex server/Gateway prioritizes usb0 (the top USB) interface by default for troubleshooting purpose.  USB Port for tethering   Trust This Device? (If Prompted): The first time you connect the iPhone to a new Flex server/Gateway, the iPhone will ask, "Trust This Device?". Tap "Trust" on the iPhone. You may need to enter the iPhone passcode to confirm. Access iPhone Settings: Open the Settings app on the iPhone. Navigate to Personal Hotspot: Scroll down and tap on "Personal Hotspot." Enable Personal Hotspot: You will see a toggle switch labelled "Allow Others to Join." Tap this switch to turn it ON. It will turn green to indicate it is ON. Important: You might see options for Wi-Fi Password or "USB Only." For USB tethering, you don't necessarily need to worry about the Wi-Fi password unless you also plan to use Wi-Fi hotspot. Check the Flex server/Gateway is online. The Gateway Status LED will be Solid Green. Gateway Status LED   Blink pattern for Internet connection   To Disable USB Tethering (iPhone): Go back to Settings > Personal Hotspot on the iPhone and turn OFF the "Allow Others to Join" switch. Alternatively, you can just unplug the USB cable from the iPhone or Flex server/Gateway Troubleshooting Tips: Restart everything: If it's not working, try restarting the phone and then the computer. Try a different USB port: Sometimes, a particular USB port on your Flex server/Gateway might be faulty. Try a different one. Try a different USB cable: Not all USB cables are created equal. Some are only for charging and don't support data transfer. Try a different cable if you have one. Disable VPN on the phone: If you're using a VPN on the phone, try disabling it before tethering, as it can sometimes interfere. Check data plan: Ensure you haven't run out of mobile data. Contact the mobile carrier: Some mobile carriers have restrictions on tethering or require a specific plan. If you've tried everything else, check with your carrier. By following these steps, you should be able to successfully set up USB tethering and get the Flex server/Gateway online using a smartphone's internet connection!

  Issue RP-C contains 2 Modbus devices of the same type on the Modbus interface, one of the Modbus devices reports error 'Value Invalid reference type for HMI' when points with HMI as control mode are downloaded.       Product Line EcoStruxure Building Operation Environment Detected in version EBO 6.0.3.112 and above Cause Modbus point with Control Mode set to HMI will fail to download to RP-C if its reference is invalid. Create a folder in an RP Application folder called 'Test 1'. Create an Analog Value object in the ‘Test 1’ folder. Create a Modbus Device and add a Modbus Analog Output Point to it. Click on the gear to the right of the ‘Value’ property in the new ‘Modbus Analog Output Point’ and reference the Analog Value/Value from step 2. Set the ‘Control mode’ of the ‘Modbus Analog Output Point’ to HMI.   Edit the reference from step 2. so that it manually looks for ‘Test 2’. A warning appears indicating that the reference is invalid and Control mode is automatically set back to ‘Write only’. Change the ‘Control mode’ back to ‘HMI’ and Save, the system displays 'Value Invalid reference type for HMI' error.   Resolution A valid reference must be defined to a Modbus point with control mode set to HMI so that it can be downloaded to RP-C.   From step 4. set the reference back to a valid one ' Test1/Analog Value/Value ' and download the object to RP-C.  

Issue Panel showing detector Calibration error. Product Line ESMI Fire Detection. Environment FFSULH1001. FFSULH1002. Cause When the contamination increases significantly and exceeds the sensitivity range for the smoke sensor, it is no longer able to perform calibration, causing a calibration error. Resolution Understanding the Calibration Process: The Esmi Ultima panel performs daily calibration and drift compensation for all addressable smoke sensors at 7 AM by default. Sensitivity and Contamination: Over time, dust and other contaminants can build up in the chamber of a smoke sensor, increasing its sensitivity. Illustration: Left Image: Clean sensor requiring 2.0% per foot of smoke to activate the fire alarm. Right Image: Contaminated sensor with increased sensitivity, requiring less smoke to reach the alarm threshold of 2.0% per foot. Trouble Condition: When the panel can no longer compensate for the contamination, it indicates a trouble condition. The Esmi Ultima panels can compensate for contamination build-up in addressable smoke detectors and addressable multi-criteria detectors. Daily calibration offsets any contamination, ensuring each smoke detector remains within its UL Listed sensitivity range. Recommended Action: Clean or replace the sensor with a new one of the same model. If you have a replacement in stock, replace it immediately.  

Issue Routers or devices with routing capabilities may not support BACnet Protocol 16 Extended Frames (1474 bytes) and only support BACnet MSTP Frame size (480 bytes), so devices that support the larger size need to receive a request with a smaller APDU defined or they will use the largest APDU they support, which will be dropped at the router. Each BACnet device has a Max APDU Length Accepted property and SpaceLogic/Easylogic, which supports Extended Frames, is 1474 bytes. Product Line TAC IA Series Environment MP-X under Tridium offer SE branded Tridium offer I/A Series MNB 1000 Building Operation EasyLogic RP-C Building Operation EasyLogic RP-V Building Operation EasyLogic MP-C Building Operation EasyLogic RP IO Expansion Module Building Operation Multi-purpose Controller Building Operation Multi-purpose VAV Cause Routers and devices, acting as routers, that support BACnet Protocol Revision lower than 16 will drop the extended frames (aka large packets). BACnet Protocol 16 introduced Extended Frames (1474 bytes) to BACnet MSTP, which increased the frame size from 480 bytes. BACnet devices have Max APDU Length Accepted, which communicates the largest frame size accepted. SpaceLogic/Easylogic have Max APDU Length Accepted =  1474 bytes. Resolution Add bacnetUtil-rt module to the station, which is included in default Niagara installation, using Platform -> Software Manager. Open Palette -> bacnetUtil Select ApduSizeOverride from DeviceOverrides folder Drag-n-drop it on the BACnet controller The default is 480 for BACnet MSTP. To disable for SpaceLogic/EasyLogic controllers communicating via IP or on MSTP supporting Extended Frames, you can change to 1474 to match the CONFIG -> Device Object -> Max APDU Length Accepted.  NOTE A: Support was added in Niagara 4.10u10, 4.14u1, and 4.15. NOTE B: This can be added to any device, so changing to 480 will indicate how much slower communication would be if using an MSTP router that does not support Extended Frames. I tried by viewing Device Report in N4.14 while capturing in Wireshark, so I could see packet timing on the wire, and it was about 3 times slower.
