Central Unit for Alarm, Monitoring and Control Systems The central unit AHD 882 is a microcontroller-operated device, designed for acquisition, processing and distribution of binary status data and analog limit values (alarms, events, messages etc.). The data (e.g. measuring point data from sensors of a ship alarm, monitoring and control system) are serially transmitted from decentralized connected external data acquisition stations and processing devices and processed by integrated alarm, display and control management. The electronics of the unit is fitted in a profile module, prepared for installation on standard profile rails in consoles, control panels or control cabinets. The cable connection is performed by two terminal lists, consisting of pluggable terminal module with cage-clamp terminals, as well as plug connectors for RS232-interface (9-pole D-Sub plug connector) and CAN-bus connection (2 xLumberg Device-Net plug connector). The central unit AHD 882 provides 18 input channels for serial transmission of data, externally acquired i.e by the following devices: • Binary Data Station AHD-PS 1 5, 1 5 binary inputs • Binary Data Station AHD-PS 30, 30 binary inputs • Binary Data Station AHD-PS 47, 47 binary inputs • Analog Data Station AHD 903-15, 15 analog/ binary • Alarm System Kompakt EDA 47, 47 binary inputs Via two CAN bus interfaces, binary status data of measuring points, which are monitored by data acquisition stations connected to CAN Bus network can be filtered and recorded from CAN-data protocol, e.g.: • Data Station AHD-SAS 1 5, 1 5 analog/ binary inputs • Navigation Light Monitoring System AHD-DPS 02

All received data are processed according to predefined project-specific configuration and distributed as processed output data to the 16 output channels of the unit, where following indication and control devices can be connected: • Alarm and Indication System Kompakt EDA 47 • Group Alarm and Indication System Kompakt EDA 47 • Cabin Duty Alarm/Engineer Call Panel AHD 406-2 The data may also transmitted via CAN bus to external stations connected to the network, e.g. colour displays AHD 651, AHD 880TC as well as colour display with The central unit AHD 882 may process and distribute binary status...
