01
Understand system structure
Present controllers, lines, call stations, calls, destination groups and function keys in clear project views.
Service for compatible D1 systems · iPhone & iPad
Understand D1 systems. Keep installations in view.
D1 Toolbox combines system structure, measurements and service functions in a clear project view – connected directly to a controller or available offline from stored VCF data.

Features
Built for field service.
Less raw terminal output, more understandable relationships – without hiding the technical detail.
02
Assess measurements
Read impedance values, calibrate references, compare history and evaluate events together with line data.
03
Document service work
Record maintenance sessions, system checks, lamp tests and executed commands in a traceable way.
04
Keep working offline
Import VCF files, retain system information locally and export selected reports or backups.
05
Parameterise with confidence
Guided forms, OPMODE safeguards and command previews help reduce input errors.
06
Record rack layouts
Arrange racks and components visually, assign controllers and include the result in documentation.
App views
Large installations. Clearly organised.
Project, controller and detail data remain separate. Every screenshot uses fictional demo data.
Optimised for iPad
Keep the context visible.
The fixed project rail keeps buildings, the overall view and controllers within reach while lines, system condition or service functions remain open in the workspace.
Project structureSystem conditionData status
Project overview
View controllers, lines and call stations across a project.
Lines & impedance
Assess values, tolerances and measurement history.
Events
Read events and assign them to the correct controller.
Maintenance
Document system checks and service steps.
Workflow
From project to measurement.
Choose the project deliberately
Controllers belong to a building. An IP address alone is never treated as proof of a project identity.
Capture system data
VCF, version, events and impedance values are read deliberately and retained with a traceable timestamp.
Review the relationships
Lines, call stations, functions, triggers and targets are brought together in a readable structure.
System data stays on the device.
The app has no account, advertising, tracking or developer analytics. Projects, measurements and VCF data are stored locally; an entered password is protected in the iOS Keychain.
Read the privacy policy →A tool for qualified technicians.
D1 Toolbox does not replace manufacturer documentation, authorisation, mandatory inspection or operational safety measures. Live functions may only be used on authorised systems and within a protected service network.
