1) INTRODUCTION
The highly innovative and versatile MULTISCAN 8+ central units the ideal solution for small
systems with up to 16 gas detectors.
The system provides for the direct connection of 8 detectors to the central unit (4-20mA) and to
additional 8 detectors that can be connected directly to the RS485 bus or via a remote module
with 8 x STG/IN8-S inputs.
Each input can be configured for different types of gas: toxic, refrigerant, flammable, and oxygen,
both for their deficiency and enrichment.
The backlit display offers an accurate indication of gas concentration and allows the display of
established alarm levels.
The central unit manages up to 38 relay outputs, of which 6 are on board the central unit and the
other 32 are via STG/OUT16S and STG/16REL cards.
The central unit is supplied in an ABS housing and can contain 2 x 12Vdc, 7Ah batteries to ensure
that the system works even in the event of a power failure.
The MULTISCAN 8+ is in the process of obtaining SIL1 and ATEX certification pursuant to
EN60079-29-1.
