Matrix Elevator Access Control

COSEC maps each credential to the floors that person — or their whole group — is allowed to reach, within the hours they're allowed to reach them. A cleaning crew badge opens floors 3 to 8 between 6 PM and 10 PM; an executive card reaches the boardroom floor any time; a tenant's staff inherit their leased floors as a group, so onboarding one new hire doesn't mean re-mapping floors by hand.

Press a floor button without authorization and the lift simply doesn't respond — no override, no exception left to the operator at the panel. The same controller extends past the lift to entry/exit doors and data racks, so floor, door, and rack access run on one policy engine.

When the fire panel trips, COSEC releases floor locks on the evacuation path and triggers hooters, so people aren't trapped behind a credential reader during an evacuation.

Unauthorized floor attempts capture a CCTV snapshot tied to the time and the credential used — the security team reviews what actually happened, not just that something happened.

Every floor request is logged: user ID, name, date, time, which elevator, which floor. Reports run elevator-wise (what happened in lift B today) or user-wise (everywhere this contractor went this week).

For buildings under tenancy or compliance review, the log is the evidence — who reached which floor, when, and whether the rules held when nobody was watching.
