Overview

Set system-wide override duration limits across multiple JACE controllers from a Supervisor station using the Provisioning service. Bulk administration for 80+ controllers.

Use Case

Prevent operators from leaving overrides in place indefinitely by enforcing a maximum override duration. This ensures equipment returns to automatic control.

Solution: Provisioning Service

Use the Provisioning service to push configuration changes to multiple JACEs simultaneously.

Step-by-Step Process

   • Add job step: SetPropertyStep
   • Configure the ORD path and value

Facets for override duration:

overrideExpiration=3600  // seconds (1 hour)
maxOverride=28800        // 8 hours maximum

Job Configuration

Execution

1. Select target JACEs
2. Run job
3. Monitor progress
4. Verify on sample JACEs

Verification

After running the job:

1. Connect to a JACE
