There are several off the shelf Bluetooth range extenders, however not all use Bluetooth 4.0 (BLE) and are robust enough to be used in an industrial environment. The i-ALERT2 sensor has not been tested for use with a Bluetooth extender, at that this time we cannot make a recommendation.
You can reboot the sensor by using a magnet over the Bluetooth icon (see image below).

Table of modes
Mode Remove Magnet Approximate time
Bluetooth Radio Toggle While Blue (Middle) LED On 3 sec
Full Unit Reset After All 3 LED’s Go out 12 -15 sec

Refer to page 14 of the i-ALERT2 IOM.
a. Confirm that Bluetooth is turned ON in the phone/tablet<br />
b. That the i-ALERT2 sensors are within range (30 -100ft).(&lt;--- Why 30 as a minimum, why not 0??)<br />
c. Confirm that the i-ALERT2 sensor is powered ON and blinking.<br />
d. Restart Bluetooth on phone<br />
e. Restart the App
The diagnostics analysis can be completed from the Mobile App, providing the mobile app has a connection to the internet. The i-ALERT2 sensor will need to be within Bluetooth range of the mobile app to transfer data to the app.
The diagnostic functions are performed on the Ai Platform. The mobile device requires web connectivity in order to provide results.

Installation/Start up

Alarm and warning levels are set automatically or they are user defined through the App. User can set levels (not exceeding 1.5 ips, or 38.1mm/s RMS) as desired by:

a. From the scan screen, select the i-ALERT2 monitor that you want to configure
b. Go to Main Menu [Ξ]
c. Go to ‘Equipment Info’
d. Select ‘Alarms and Warnings’
e. Change setting as desired using “+” and “-“
f. When your changes are complete, click “Save”

Note: If the alarms are set manually, the automatic baseline feature is disabled.
Video Reference:

Refer to page 45-46 of the i-ALERT2 Application Guide.

When an i-ALERT2 sensor is moved to a different piece of equipment, it is recommended to use the following commands which can be found under ‘Main Menu’ -> ‘Equipment Info’

a. Choose ‘Erase all stored data from i-ALERT2’
b. Choose ‘Start New Baseline’

Note: The Baseline process will require 25 hours of equipment runtime to establish.
Video Reference:

Refer to page 50 of the i-ALERT2 Application Guide.

The i-ALERT2 sensor is only required to sense light during the initial turn-on period where the yellow/red arrow sticker is removed. During normal operation (once started) ambient light is not necessary for continued operation of the i-ALERT2 monitor. If no ambient light is present during initial start, a flashlight or other source can be used to enable the sensor.
No, once operational, the i-ALERT2 sensor will continue to monitor regardless of ambient light levels.
sensor-axes-1.png sensor-axes-2.png The axis can be changed from the App to account for different installations. It is as easy as following the steps once the sensor is discovered and choosing the desired axis as shown below.

‘Main Menu’ -> ‘Equipment Info’

Note: the Z direction is limited to 600 Hz for Sensors manufactured before August 2018 and 700 Hz for those manufactured afterwards.
a. App detects the new sensor
b. Register the sensor and claim ownership if you/company are the legal owner
c. Name the sensor
Note: By default the sensor has the radio ID as the name. You can change this to a more common name (e.g. VAC PUMP-506). There is a 12 character limit.
d. Choose the sensor position on the asset (e.g., motor drive end, equipment non-drive end, etc.).
e. Choose the sensor orientation (i.e. which axis are radial, axial, etc.)
f. Choose the method for setting the alarm and warning levels.
(e.g. Auto baseline after 25 run hours, set manually or use existing settings)
g. Assign sensor to asset
  1. Create asset
    1. Configuration
    2. Define the plant level the sensor is in
  2. Assign to existing asset
  3. Search for asset

Please bear in mind that the i-ALERT2 sensor is associated with a specific piece of rotating equipment and must be re-associated through the App if the sensor is moved to a different machine. The steps to complete this within the App are as follows:

  • Navigate to Equipment Information from the Main Menu
  • Choose Erase All Stored Data from i-Alert
  • Choose Change Asset Details
  • Choose Change Sensor Name
For customers who would like to mount the i-ALERT2 sensor with a magnetic mount, we now have the i-ALERT2 Magnetic Mounting Adapter (Part number: K09925A). Please note that the adapter will limit the upper frequency range to 700Hz and because of the size the temperature accuracy is also reduced.
Yes, just be sure to set an appropriate sensor TAG name and to change the i-ALERT2 sensor’s position under “Equipment Info Equipment Details” accordingly. Or set it up in the registration process. The sensor TAG and position can also be set during registration of a newly discovered sensor when prompted and associated to the same asset.
The i-ALERT2 sensor can be mounted on vertical equipment using any of the same 3 mounting methods used for horizontal equipment. Care should be taken to mount the i-ALERT2 sensor over the bearings. If you want to keept he default orientation make sure that the row of LED’s are aligned with the shaft of the rotating machine. In the case of vertical pumps where one end is submerged, the i-ALERT2 monitor can be used on the dry end only.


If you mount the sensor other than the default way, be sure to reset the axes orientation Refer to question 10 above. Refer to the i-ALERT2 Application Guide, page 26.
The i-ALERT2 sensor can be mounted on non-Goulds equipment using either the drill and tap method or the epoxy method or the ITT Magnetic Adapter. Refer to the Applications Guide for more detailed information, pages 20-27.

Method 1: The i-ALERT2 sensor can be installed by using the center fastener directly to equipment with a threaded hole to accept a ¼-28 x 1.125” screw.

Method 2: Use a ¼-28 x 1.5” screw that goes through the i-ALERT2 sensor, through mounting adapter (p/n C10824A or C10987A), and into a drilled and tapped hole in the equipment.

Method 3: Use a ¼-28 x 1.125” screw that goes through the i-ALERT2 sensor and into mounting adapter (p/n C10824A or C10987A). The mounting adapter can be adhered to the desired location using an epoxy putty that is appropriate for the given application.

Method 4: Use a Magnetic Mount (p/n K05163A). If using this mounting option, the vibration frequency range is limited to a maximum of 700Hz in all directions, and temperature readings will be adversely affected.


There are factors which can significantly affect temperature readings such as ambient temperature, airflow over the sensor, and mounting method. Temperature as measured by the i-ALERT2 is intended to identify changes over time. The User can input an offset to match the actual absolute temperature value by going to the “Equipment Information” page under Menu and then navigate to Temperature Offset under Sensor Settings. There The user can input the value of the offset. The i-ALERT2 temperature corrections are shown below.


In some cases, the runtime as measured by the i-ALERT2 sensor can differ from actual equipment ON time.

Case 1: On very smooth running machines, the vibration levels are too low to be detected by the default settings. In this case, navigate to Equipment Info -> Runtime Settings, then enable Quiet Mode. There is also a slider to adjust sensitivity further if required.

Case 2: Runtime data is acquired on the i-ALERT2 wakeup cycle of every hour. If the equipment is determined to be running at the time of the check, the counter is incremented by 1 hour. For short equipment cycle times, this can lead to differences from the actual equipment ON time.

Diagnostics can be enabled from within the AI Platform or via either version (IOS/Android) within the Mobile App.
No changes to alarm settings will take place upon enabling diagnostics.
It does not change the baseline taken by the sensor used for setting alarm levels, nor will it change the baseline (alarm/warning levels) if manually set by a user. Baseline, as referred to in the context of diagnostics, is the selection of an FFT reading that represents normal operation of the equipment under normal operation. This reading is used within the diagnostic algorithms to detect impending failures.
It is not mandatory, but will greatly enhance the accuracy of the analysis. As such, it is highly recommended.
No changes needed to the mounting requirements for diagnostics accuracy.
The same procedure as before (rename sensor, reset alarms and warning levels to the new equipment), AND taking a new baseline FFT reading is recommended.
More sensors will yield more accurate results. It is recommended to have (in general) a sensor on the drive and free end of the equipment, and at least one sensor above the bearing on the output shaft of the motor or driver.
Absolutely. The diagnostics will work on many different machine types, from any manufacturer.


a. Download new information
b. Download new FFT
c. Wait for download to complete

In general, if the i-ALERT2 sensor has been in communication with a smart device (tablet, phone) which has been connected to the web, the data can be recovered up to the last sensor connection time. Refer to pages 42-44 of the i-ALERT2 Application Guide.

Default Temperature: 80 ⁰C (176⁰F).
Default Vibration Alarm: 0.5 ips (12.7 mm/s)
Default Vibration Warning: 0.4 ips (10.2 mm/s)

Temperature Alarm: 2 x Average of 25 run hours
Vibration Alarm: 2 x Average of 25 run hours
Vibration Warning: 1.75 x Average of 25 run hours

a. Make sure it has been collecting data for at least 2 weeks
b. Make sure that you have successfully downloaded the data

Refer to pages 42-44 of the i-ALERT2 Application Guide.

Data recording: 1 hour (Default) Configurable down to 1 min under “Equipment Information” in the “Menu” tab
Alarm check: 5 min Configurable down to 1 min under “Equipment Information” in the “Menu” tab

Note: If the sensor acquires 2 consecutive alarms in a row it will capture a new data point and an FFT/TWF.

Using AI Platform
Refer to pages 63-68 of the i-ALERT2 Application Guide.
Without AI Platform A report can be generated and emailed, or when viewing the trend the upload button can be selected and the raw data (in CSV format) can be viewed or sent by email.

a. Data points can be viewed by clicking the upload icon 26-upload-icon.jpg from the trend screen, where individual points can be viewed in tabular format.
b. Raw data (CSV format) can be exported via email by tapping the upload icon a second time.
c. Show how to select raw data export from routes The following video link demonstrates this:

Yes, please see steps detailed in the previous question.
Data can be extracted manually and sent to a DCS/ SCADA in CSV format. See steps in question 11 above.
All of the equipment data (details, curve, BOM) comes from the i-ALERT Ai Platform. To get access to the equipment information, the smart device will need internet access.
The i-ALERT2 sensor stores data on the device and that data is shared with the App. The App will back up the data and access the equipment records through an internet connection.
The i-ALERT2 sensor stores data (3-axis vibration, kurtosis, runtime, and temperature) every hour for 180 days. After 30 days the data is summarized into a weekly max, min and average values weekly, which is stored up to 5-years.
FFT, TWF and overall RMS measurements are acquired on two consecutive alarm readings (maximum once every 48 hours). The i-ALERT2 sensor continues to take overall RMS measurements every 5 minutes, storing them hourly.
• July 2015 to July 2018 the frequency range is X: 10-1,000, Y: 10-1,000, Z: 10-600
• August 2018 to Present the frequency range is X: 5-1,100, Y: 5-1,000, Z: 5-700

Use of the Magnetic Mount adapter will limit the upper frequency range to 700Hz for all three axis.
Baseline levels within the diagnostics are either user selected (i.e., selecting an FFT reading as baseline that represents normal equipment operation), or if not selected, the system will utilize a synthetic baseline. It is preferable to use a real (user acquired) baseline FFT for maximum accuracy.
The diagnostics can be performed on data up to 6 months old.
Diagnostics utilize changes in the trend data as well as information contained in the FFT and Time waveforms to calculate potential issues.
Diagnostics has no effect on stored data.
There are no changes to any stored measurements by the Diagnostics System.


Under normal operating conditions, the battery should last 2-2.5 years. Battery life is temperature and use dependent. In general, there will be an increase in battery life with lower temperatures and decrease with higher temperatures. Connecting and downloading data from the sensor will also use power. In the 3 (three) year battery life we have accounted for one dashboard connection per day and an FFT/TWF sample every other week. Using the product more than this will naturally reduce the battery life faster. The nominal battery life is based on:

a. Temperature: 18°C (65°F), average ambient
b. Dashboard connections (including trend download) of once per day
c. FFT and Time Waveform usage of one tri-axial request per 14 days
d. Operation time in Alarm at most 25% of total time

The i-ALERT2 sensor is designed and manufactured in the USA.

a. Faster downloading speeds resulting in faster data viewing
b. Run-time counter improvements; sensitivity adjustment, using an adjustable slider bar for smooth running equipment like motors
c. Hourly data storage increased from 60 days to 170 days
d. Latching alarm shown as “Last alarm
e. Battery Optimization for better life
f. Ability to set alarm check rate (1-5min) and data acquisition rate (1-60min)

In the App go to “Equipment Info  i-ALERT Information” where the sensor version number will be shown., Alternatively, for the i-ALERT 2 the sticker on the back of the sensor will have a manufacturing date after 8/22/2016.
a. The unit is in a factory sleep mode: The unit will turn ON when the sticker is removed from the LED window and it is exposed to light. (Note: If it is located in a dark environment you may need to shine a light on the unit.)

b. The unit has been shutoff: The unit can be turned back on by placing a magnet over the lower right hand side (on the raised Bluetooth icon) until the all LED’s flash rapidly then stop. The magnet is then removed immediately after the LED’s stop flashing. The unit will then restart automatically.

c. The unit has no power: To achieve the intrinsically safe rating, the battery is encapsulated and cannot be replaced. If the unit is within the warranty period check with your sales contact about a replacement. If it is not under warranty, then a new unit can bepurchased.

If your i-ALERT2 sensor has failed within the warranty period, your salesperson for a RMA to return the failed unit, and obtain a warranty form required for replacement. If you do not know your local sales contact please use the following link:

• Select a location central to the nearest cluster of i-ALERT enabled machines. The typical range from the i-ALERT Gateway to the i-ALERT sensors is 100 to 250ft (30-80M).
• To verify what i-ALERTs are in range. Open the i-ALERT Mobile App and go to the Scan for Devices Screen to verify what i-ALERT sensors are in Bluetooth range.
• Use a mobile device with a cellular connection to check signal strength. The location should have at least 1 bar (2 preferable) of reception.

For more information please go to:

​• The i-ALERT® AC Gateway is by default shipped with a 110 VAC/240 VAC cord separately.
• The gateway can be optionally ordered to be powered from 9-60VDC.

• The i-ALERT Gateway will automatically configure to the cellular network and detect any iALERT sensors in range.
• Depending on the number of i-ALERT sensors this process will take 10-60 minutes.
• Once you log into the i-ALERT Ai Platform you will see a wireless icon next to an i-ALERT sensor that is receiving data via the i-ALERT Gateway.
Please see the instructions that came with the device to get the SSID and Password needed. Then follow the instructions on the sheet.
To get the instructions please go to:
To make use of the Gateway the user needs to have access to the Ai Platform.
The ideal case would be to have a location where cell service is available but if this is not the case then please contact i-ALERT team at:
phone: +1 315-568-7290 To see what options are possible.
Although very beneficial, a Gateway is not required to use diagnostics.

Pressure Sensor

Diagnostics (currently) does not utilize the pressure data if it exists on a machine.


An Ai subscription with diagnostics is required to use diagnostics, however the diagnostics can be accessed through either the mobile app or the Ai Platform.
For equipment not listed please contract the i-ALERT engineering team for evaluation.  Automated diagnostics may be available.  Depending on complexity of the machine train a one-time non-recurring setup fee may be required for this service.  
The automated diagnostics will work with only one sensor per machine train.  However, for the best accuracy it is recommended two i-ALERT sensors are installed on the driver inboard bearing and driven equipment inboard bearing for bearing spans less than 30”.  For larger equipment with bearing spans greater than 30” it is recommended an i-ALERT sensor to be installed on both the inboard and outboard bearing. 

The automated diagnostics will work with machine trains in which there is an intermediate power transmission device such as a belt/chain or gearbox.  Below are examples of recommended sensor placement for these types of machine trains. 

To get automated diagnostics on your current i-ALERTs you will need to upgrade the i-ALERT to the diagnostics bundle which requires an annual subscription. The Diagnostics bundle includes the automated diagnostic software and access to the Ai Platform for each sensor with a subscription. 


With regards to the Diagnostics rules engine, the lack of certain information precludes certain faults from appearing in the output. For instance, if you omit any information about a coupling, the system cannot output any faults related to couplings, such as misalignment, coupling imbalance, excessive wear, etc.; Likewise if you do not tell the system the speed is variable, it will not allow reasonable bounds to be applied to the expected run speed. This could result in incorrect fault calls due to unexpected peaks in the spectrum. The optional information that is related to the machine (i.e. Manufacturer, Model, Manufacturer Serial number, etc.) are only for bookkeeping as of now, in the future they may be used to look at larger datasets for a specific machine make/model.
