What is the optional 4-eyes principle (dual control) for safe locks?

The 4-eyes principle (dual control) is an optional electronic-lock mode that requires two different people to each enter their own valid code before the safe will open, so no one can access it alone.

Kaba Combi B90 Combination Lock for Safe with Emergency Key

Item no.: KB-82132/3001

The Kaba Combi B90 is an electronic code lock for safes with a keypad and turning knob. Each user opens the safe with a personal 8-digit code (2-digit ID plus 6-digit PIN), and an emergency key opens the lock mechanically if a code is lost.

Besides the master code, the lock holds an optional manager code, user codes and a courier code — up to 90 codes in total. It offers a time delay with confirmation window, dual-code opening, a silent alarm when connected to an alarm system, and an audit trail of the last 960 events that can be read out with the optional PC software. After three wrong codes the keypad locks for a set period. The lock runs on two AAA batteries in the input unit.

Currently, we are not able to sell this lock separately. It can only be bought together with a safe.
