and must be ordered seperately�� The device continuously
monitors the container pressure and in the event of the
pressure dropping below 20��3 bar (294 psi) the switch
operates to enable the condition to be signalled to a control
unit��
This low pressure switch is the primary supply, (option
#1), of a dual source component used in order to maintain
the supply chain and ensure that adequate stock levels are
available to fully support customers and installers��
