The digital, easy programmable and flexibly expandable center PSS-224C of the VARES-3000 system takes over the audio- and alarm management for devices with up to 224 speaker lines, or switching contacts.
In connection with the extension unit PEU-056 B, of which a total of 3 units can be operated on one PSS-224C, the project specific extension from 8 up to 224 lines in eight intervals is easily possible.
The basic device PSS-224C and PEU-056B are offered without a relay card, but depending on the requirements 3 different types are available. As an innovation the relay card PRC-508B including the evaluation of the amplifier and loudspeaker monitoring according to IEC 60849.
10 monitored and 2 unmonitored isolated inputs enable a remote regulator of the VARES-3000 center. The easy programming of the center PSS-224C is carried out via the computer software “ConfigV3000”, as in all devices of the “VARES-3000 System”.
