regarding alarm abnormality

sir,
in my project there is a problem by which all alarm are suddenly enabled due to a raw valve #2147483647.
when this raw valve arrive ,then all bit will be high and alarm will be enabled. 
so this is a false state.
how to disable all alarm when all bits are high or when value #2147483647 is arrived.
we have to disable alarm only at this condition.

thankyou
