3.2 Power Supply

The EX-6100 is powered from an 8 – 24 volt dc, 5 W maximum output supply. This may be either:-

a) An independent supply powering one or more units.

b) A supply that is an integral part of a control card within a monitoring panel.

3.3 Analogue Output

The analogue output provides a means of indicating to external equipment (e.g. data loggers, remote displays, control cards) the

gas levels currently being detected by the system. The output is in the form of the industry standard 4 to 20mA current source.

The analogue output is factory set such that 4mA represents zero gas and 20mA represents the full scale gas level of the EX-

6100.
