Analogue status – alarm values
In Table 34, the analogue values that indicate an alarm state are shown for various devices. For
some devices other value ranges are used to indicate such conditions as fault, service, pre-
service and pre-alarm.

Notes:
When the calculated "N+" values fall outside of the minimum/maximum levels, the minimum/maximum
levels take precedence. N is the nominal idle value read on a daily basis. N value adjustment is limited to
10 counts maximum, this avoids sensitivity shift in a smouldering fire situation.
