1) INTRODUCTION
The MULTISCAN++S1 is a gas detection control unit designed to meet the widest range of
flexibility required by the market.
The control panel is based on a powerful microprocessor which provides a wide range of self-
diagnostic procedures to detect and locate possible faults.
Extremely flexible and reliable, it can manage up to 64 or 128 or 256 gas detectors (according
to the different 4 versions). The detectors can be either of addressable type, directly connected
on buses, or 4-20mA analogical types connected via 8-input STG/IN8-S remote modules.
System architecture also includes 8 on-board machine relays and the potential to expand
outputs up to 256 using remote STG/OUT16-S modules and 8-relay boards. Up to 4 serial
buses can be connected to the unit.
The unit allows for three alarm thresholds to be set for each detector. The alarm threshold
activation mode changes according to the type of gas detection profile and connected detector
The unit is inserted in a plastic box complete with 27 Vdc 4 A power supply.
