Why test alerts in the yard?
A device can report its position and still miss an alert. The ignition wire sits on the wrong source, a threshold is too high, a geofence is drawn on the wrong account, or the panic button goes to nobody. You find out on the day it matters. A short yard test finds it on the day of installation.
Some alerts need a real event: speed, harsh braking or a long idle. In a yard you do not create the danger. You lower the threshold for the test device, trigger it at walking pace, and put the threshold back.
Closed yard only, never a public road. Keep a spotter outside the vehicle and stay under the yard speed limit. Test the immobilizer only with the vehicle stationary and the engine off.
How the result is worked out
The vehicle result is Ready when every alert that applies passed, Check when something is late, pending or not restored, and Not ready when at least one alert failed. In the example: 9 pass, 2 late, 1 fail, 1 to restore, so the vehicle is Not ready.
Test values and maximum delays
The file ships with example test values: a 15 km/h speed limit, a 2-minute idle limit and a 3.0 m/s² level for harsh braking and acceleration. The 3.0 m/s² level is a typical starting value. Adjust it after the pilot. None of them is a device specification. Pick values your yard allows, and keep the original values on record.
The maximum delay is yours too. It depends on the reporting interval, the network in the yard and how the platform shows events. A power-cut alarm on a device without a backup battery may only arrive after the power is back, so its example maximum is longer.
Typical value. Replace with your device datasheet value.
When to run it
- After every new installation, before the vehicle goes back to work.
- After a configuration change or a firmware update.
- After a repair that touched the wiring or the device.
- When a driver or the control room says an alert never came.
Limits
The script records what you observed in one test. It does not certify the device, the installation or the platform, and it does not describe the alerts of any particular Tracom model. Which alerts a device sends depends on its model, firmware, configuration and accessories.
