INTRODUCTION

The 5701 Series Control System is a microprocessor based system
which displays the reading and status of connected gas detectors. The
system
provides complex alarm handling facilities with a full
maintenance capability.
A rack system is fitted with a number of single channel control cards
each with an associated field/ relay card which provides the necessary
sensor input and optional relay output connections. Simple alarm
handling and operation is provided by each channel control card.
Complex alarm handling is achieved by communication between a
specified number of control cards via the backplane of the rack.
An engineering card is fitted to each rack and provides control of the
rack backplane communications, control card interrogation and
facilitates maintenance. In addition, optional modules fitted to the
engineering card can provide additional system outputs.
System power supplies, auxiliary power supplies and battery back up
systems are all normally connected to the rack via a DC Input Card,
however, for high integrity system installations power supplies can be
connected directly to each individual control card.
