11.2.7  Passing EVS Control
Passing of EVS Control is allowed when two LOCs have the same priority. When it is possible to pass control, a prompt (similar to 
Figure 11.2) will display in which the user can: request control from the LOC with EVS Control, enter an access code with the EVS 
Super User profile option to override the other LOC, or wait for the lockout timer to expire (if applicable). 
Figure 11.2  Request EVS Control with Lockout Timer Active
When passing EVS Control between two EVS Super Users, the user is not shown the prompt screen. Instead, a request for EVS Control 
is automatically made. Additionally, the lockout timer does not apply for EVS Super User.
When a request for EVS Control is made, the LOC with EVS Control will be shown a screen (similar to Figure 11.3), even when in 
another menu, except programming menus, indicating that another LOC is requesting EVS Control. The piezo buzzer on the LOC with 
EVS Control sound when an EVS Control request is active to alert a nearby operator of the request.
Figure 11.3  EVS Control Request on LOC with EVS Control
Once EVS Control is passed to another LOC, the new user will assume the system AS IS. This means that the event that was set to be 
playing at the previous LOC and all output areas it was playing in do not change. 
11.2.8  Exit EVS Control Menu
The user can exit the LOC EVS interface by pressing the left arrow. The user will be returned to the idle screen which indicates that the 
LOC still has EVS control. 
11.2.9  Relinquish EVS Control
Relinquishing EVS Control is accomplished by pressing the EVS Control Key from within Message Mode. A screen will be displayed to 
ensure the user wants to relinquish EVS Control. EVS Control will be automatically relinquished after a time-out on this screen. When 
EVS Control is relinquished, the system stays in the Manual EVS State. EVS Control can then be gained by another LOC or again at the 
same LOC.

11.2.10  EVS Reset
An EVS reset is accomplished by pressing the RESET button from an LOC. The user will be prompted to reset either the fire system or 
emergency system. After an EVS reset, the LOC will automatically exit the LOC EVS interface.
11.3  EVS Super User
The EVS Super User access code profile function provides the ability to override all EVS Control rules and gain EVS Control. The EVS 
Super User is the highest priority user in the system. The EVS Super User has several features that differ from the normal user:
1. Any alarm activated while under EVS Super User Control needs to be reset using an EVS Super User function enabled access code.
2. LOC priority and LOC lockout timer are ignored when passing EVS Control between EVS Super Users at LOCs. If another EVS 
Super User attempts to gain EVS Control from an LOC, an EVS Control request is presented to the EVS Super User at the LOC that 
currently has EVS Control.
NOTE: In order to perform an EVS reset, the display must be associated with the EVS-VCM / EVS-RVM.
