The MULTISCAN++S1 are advanced multifunction gas detection control panel designed to meet with the increasing requests for highly flexible systems. A powerful microprocessor allows a wide range of self-testing facilities to take place to detect and localize possible failures. The system allows the connection of gas detectors and remote input/output modules via 2 open loops to be extended up to 4. The control panels can manage and monitor up to 256 gas detectors.
