The VOC should be in a secure area of the stadium and have an overall view of the stadium bowl. The size, configuration and furnishings of the VOC should be designed to accommodate all equipment and personnel necessary to manage the safety and security of the stadium efficiently. When designing a VOC, the stadium authority should consult with the relevant agencies who will be using the VOC or providing a response in case of emergency, such as the police or fire service.
The VOC must remain operational in the event of an emergency. All equipment in the VOC must have a secondary power supply. In addition, any equipment that will require a reboot sequence or not tolerate a short outage must be on an uninterruptable power supply.
The VOC will require connection and access to the following stadium systems:
Public address (PA) system: the public address announcer, who may be part of the entertainment or infotainment team, should have communications connections to the VOC, but should not operate from the VOC. Instead, they should be located in a separate room within or next to the VOC to facilitate good communication between the two areas. The PA system is the main form of direct communication with spectators. It can also be used as a form of communication between stadium management and stadium staff during an incident or where mass notification is required. The electronic video screen may also be used as part of the notification process (see below).
The VOC should have a PA override facility to give designated individuals/operators and security staff priority use of the PA system in an emergency. The system should be intelligible so that broadcast messages can be heard under reasonable conditions (including emergencies) by all persons of normal hearing, including those people who are waiting to gain entry, and in any part of the stadium to which the public has access. Ideally, the PA system should be designed to allow broadcasts to be made to specified individual areas both inside and outside the stadium, including the pitch.
Fire alarm control panel: if the stadium has a secondary fire control panel, it is recommended that this be located in the VOC (refer to Sub-Section 5.4.1).
Electronic video screen control system (where installed): as with the public address announcer, the main operator of the video screen(s) should not be located in the VOC but in a separate room nearby to allow communication between the two areas. Safety messages should be pre-scripted and passed to the video screen operators for display (refer to Sub-Section 5.7.4).
Closed-circuit television (CCTV): adequate CCTV systems with sufficient monitor screens and camera controls should be located in the VOC to undertake surveillance monitoring of the stadium and its immediate vicinity.
