The DS216 controller can directly supervise up to 16 digital supervised inputs and 4 relays. The capability is extended up to 24 inputs by addition of a plug-in 'EXT-84' extension board and up to 64 relays by the connection of the plug-in 'EXT-RL12' extension board and of three satellites via the second communication bus. Further increase in capability is achieved by connecting several DS216 within the installation.
Alarm events are transfered on a real time basis to the host, through a RS485 bus or a TCP/IP network, by the addition of an 'EXT-TCP' or 'EXT-TCP84' extension board.Each input is supervised, which means that it controls the contact itself (sensor under alarm or not) and the status of the line (normal, short or cut).
Programming and supervision of the DS216 is extremely user-friendly via the use of Amadeus 5 software. Once programmed, the operating tables are downloaded to the DS216 and define the system behaviour:
-Inputs physical status: 'Normally Open' or 'Normally Close'
-Input state: 'Armed' or 'Disarmed', either manually or according to time zones
-'Reflexes': activation of one or several relays upon detection of specific input(s) status
Up to 4.500 alarm events can be recorded in the controller internal memory. The second bus of communication allows either redundant communication with the host, or activation of reflexes on other controllers (with or without PC intervention) or satellites connection.
Troubleshooting is eased thanks to on-board leds (input and relay status, communication process indicators, etc.). The firmware, in flash memory, is easily upgraded from the host.
