The network control panel (NCP-2) can be wall-mounted within room or closet. It provides the functionality of numerous rack-mounted components, reducing the costs, energy and space needed for equipment. The panel allows the administrator to establish timer, paging and keypad zones. There are no restrictions on the size of each type of zone and they can be non-contiguous. The administrator can also set the volume and equalizer levels for masking, paging, program ramp-up, timer schedules, select paging channels and create user limits for each programmable keypad. The panel uses non-volatile memory so that these settings are preserved in the event of power failure. The panel’s calendar-based timer utility allows the administrator to schedule changes in the sound masking volume to match expected occupancy levels. Each panel offers nine timer zones. The administrator can establish different schedule for each zone and each day of the week, with up to nine volume changes per day. The administrator can also program unique schedules for up to 30 individual dates, such as holidays. The panel adjusts for daylight saving time.
