1) INTRODUCTION
The
MU+S1/32B
is a gas control unit designed to offer 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 40 detectors, 8 directly connectable to the
panel and 32 gas detectors on the 2 serial lines the panel comes complete with.
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 relays and the possibility to expand outputs up to
64 using remote STG/OUT16-S modules and 8-relay boards.
Three alarm thresholds to be set for each detector. The alarm threshold activation mode
changes according to the type of gas detection profile chosen and the detectors
connected.
The unit is housed in a plastic box complete with 27 Vdc 4 A power supply.
