As the OutLock II, this terminal has the ability of storing the employee's information in order to authenticate their cards and to validate one code per card. What distinguishes them is that the OutLock I does not possess the display with the current time, therefore it is mostly used for access control.

Although different in appearence, these terminals are compatible with the terminals of the Evolution line from Acronym, which means that it is possible to install Evolution and OutLock terminals in a same network .
