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 centralunitis supplied in an ABS housing andcan 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.

2) INSTALLATION

2.1) Assembly and connections

Remove the 4 screws at the 4 corners of the box and remove the front part of the central unit box.

It is now possible to choose where toplace the cables. We recommend placing the cable for entry

by using a suitable cable press.

Secure the back of the central unit to the wall by using its appropriate holes.

Fig. 2.1 a) Central unit box

Connect the tri-polar network cable to the power supply (minimum 1.5mm2per pole) and

secure it with the specific wire clamp.

Power on the central unit, and connect the red and black fastons of the power supply to

the two 12 V 7 Ah lead buffer batteries, in a series
