DESCRIPTION
The RND-1 is designed to annunciate network events (alarms, troubles and supervisories) on a MPC-Net network. It is capable of scrolling through network events, while acknowledging these events either globally or from the RND-1 only. Alarms may also be silenced globally. There is also the ability to reset all panels on the network or just the RND-1. Also, a network event history can be retrieved. The RND-1 can log on to any panel on the network. At that point, access to user and maintenance levels for that panel are available at the RND-1.

The 80-character display is used to display event data, including alarms and troubles, identification of zone or device, and presentation of history. The display is controlled by a set of four push button switches com-manding the control processor. A back light is included in the display to assure visibility in low light, but to conserve power, it is only activated during a reported event or on operation of a display control switch.

Individual LEDs on the panel are provided to indicate System Alarm, Pre-Alarm, Supervisory, Alarm Silenced, System Trouble and AC Power ON. Direct push-button controls are provided for Alarm Silence, Trouble Silence/Acknowledge, Menu and System Reset.

Up to 16 RDC-2 remote annunciators can be slaved off one RND-1. The RDC-1 duplicates the display and control functions of the RND-1.
