Is Your Energy Isolation Security Troubled by These Issues?
Key & Lock Chaos
Hundreds of mechanical locks and keys are time-consuming and error-prone to distribute, retrieve, and track.
Uncontrolled Access
Lots of keys, lots of locks. Failing to restrict who, when, and which equipment can be accessed.
Untraceable Process
Who released the isolation point? No evidence after an incident makes accountability impossible.
Vanma Lock Solution

One Electronic Key Instead of Keys
The Vanma system replaces hundreds of physical keys with a single smart electronic key. Manage lock permissions—issue, revoke, and track status—with one click in the software. Say goodbye to cumbersome paper logs and manual key counts, boosting management efficiency by over 80%.

Flexible Access Control
Precisely configure “who can access which equipment, and when” in the backend. Permissions auto-expire after tasks, eliminating unauthorized operations at the root. Elevate safety protocols from human reliance to programmable, technical assurance.

Audit Trail
Every lock/unlock action is automatically logged—who did it, when, and where—then encrypted and uploaded. This creates an immutable audit trail, providing irrefutable evidence for incident investigation and clear accountability, fully meeting stringent compliance and safety audit demands.
