the individual instrument fault relay. The selection permits setting the relays to a
latching or non-latching state. In a latching state, the relay will remain activated until
the user manually selects the Enter Key. In a non-latching state, the alarm relay will
automatically reset once the gas concentration has returned to 20.9% for oxygen.
