Parameter set-up

For details on how to configure and install a device to be able to immobilize an asset, see the links below.

Immobilization Install - Asset can be immobilized from the server

Immobilizer Install - Asset starts after valid Driver ID Scan

To add the layer of after-hours immobilization (after one of the above installs is set up) please see the parameter set up below.

Immobilization After-Hours Parameter: 

• Disabled: After-Hour Immobilization function disabled
• Active: Immobilizer state active (immobilizer on - output set High)
• Inactive: Immobilizer state inactive (immobilizer off - output set Low)

After-Hours & Time-Zone Parameters on Devices: Aligning the after-hours and time-zone parameters on devices is essential for the accurate execution of after-hours immobilization. 

Override After-Hours Immobilization:

There are four options that provide the ability to override after-hours immobilization:

1. Override Command - please contact DM Support for OEM WebAPI documentation
2. Prioritized Driver ID
3. Sending an “activate” or “deactivate” command via the mobile app depending on immobilization set up: 
   1. "Activate" command on basic remote message with a configured expiry duration in the system parameters - please note for this option to work, the immobilization set-up will need to be active high set to “no” and immobilization after hours set to “inactive”.
   2. "Activate" command on scheduled remote message as long as a configured expiry duration is set in the system parameters - please note for this option to work, the immobilization set-up will need to be active high set to “no” and immobilization after hours set to “inactive”.
   3. "Activate" OR "Deactivate" command on timed remote message
      *Options a & b require opposite triggers from the actual expected logic, whereas option c can be setup to have the same trigger logic as the output logic.
4. Updating the system parameters to disable after-hours immobilization via Device Manager
