The Unexpected Asset Removal (UAR) alerts functionality in ON!Track helps ensure that your assets remain secure and accounted for. By using ON!Track Smart Tags and gateway tracking, the system can detect and alert you when assets are moved unexpectedly.
Why are UAR alerts triggered
To alert you when an asset leaves a location with a gateway, but no one has checked it out or transferred it.
These alerts help you quickly spot:
- Possible theft or loss
- Tools leaving without proper documentation
- Movements that don’t follow your usual processes
How is a UAR alert triggered
A UAR (Unexpected Asset Removal) alert is created when all of these conditions are met:
-
The asset is tracked by a gateway
- The asset has an ON!Track Smart Tag.
- It is assigned to a location that uses a gateway (such as a warehouse, van, container, or machine).
-
The gateway had been regularly scanning the tag, but the tag then moves out of the gateway’s Bluetooth range.
-
No transfer is recorded
- No one has manually checked out or transferred the asset in ON!Track.
- The system also does not detect an automatic transfer to another gateway location.
-
Because of this, ON!Track still believes the asset is at the original gateway location.
-
The tag stays out of range long enough
-
The tag stays out of range for the full system‑defined “gone interval.”
- AI G125 tags: alert normally appears after about 13 minutes.
-
TU600 tags: alert normally appears after about 25 minutes.
-
The tag stays out of range for the full system‑defined “gone interval.”
-
Alerts are allowed at that time
- UAR alerts are turned on for that type of location.
-
The removal happens during a time when alerts are not suppressed. (If it happens during a suppressed period, no UAR alert is created, even if the asset is removed.)
-
ON!Track creates the alert
- Once all conditions are met, ON!Track creates an Unexpected Asset Removal alert and shows it in the Alerts list (and sends notifications if enabled).
This article explains how combinations of parent and child assets interact with this functionality in different tracking scenarios:
1. Gateway-Based Asset Alerts
-
Stationary Gateway-Based Asset Alerts:
- Assets (parent and child) tagged with ON!Track Smart Tags trigger individual alerts if moved out of range from a fixed-location gateway.
- You can expect a UAR alert to appear about 13 minutes after a tag leaves the gateway range if it is using an AI G125 tag.
-
Example:
- A drill with a Smart Tag is assigned to a warehouse that has a stationary gateway.
- Someone takes the drill out of the warehouse without checking it out in ON!Track.
- The Smart Tag moves out of the gateway’s Bluetooth range and stays out of range for several minutes (for example, about 13 minutes with an AI G125 tag).
-
ON!Track creates a UAR alert because it detects that the drill has left the warehouse unexpectedly.
-
Mobile Gateway (e.g., Van, Container, HE):
- Tagged assets assigned to a mobile gateway-enabled storage unit trigger alerts individually, based on configured rules.
- For TU600 tags, UAR alerts usually appear after about 25 minutes once the tag moves out of the gateway range.
-
Example:
- A laser measure with a Smart Tag is assigned to a service van with a mobile gateway installed.
- At a jobsite, someone removes the laser from the van without recording a transfer in ON!Track.
- The Smart Tag goes out of the van gateway’s Bluetooth range and remains out of range long enough (for example, about 25 minutes with a TU600 tag).
- ON!Track creates a UAR alert because the system believes the laser has left the van unexpectedly.
2. Alert Closure:
A UAR (Unexpected Asset Removal) alert closes when either of the following happens:
-
The asset returns to the gateway area
- The asset comes back to the same warehouse, van, container, or machine where the alert was created.
- The gateway starts detecting the Smart Tag again.
-
ON!Track recognizes that the asset is back and automatically closes the alert.
-
The asset is correctly moved in ON!Track
- Someone records a proper transfer or check‑out for the asset (for example, from a warehouse to a jobsite or from one van to another).
- Once the move is saved, ON!Track knows the asset has a valid new location and closes the alert.
