In the above table the greyed section indicates flow rate recording while the white section indicates detector
and alarm level recording.
At the slowest recording rate, one month of data can be recorded. The factory default setting is 8.
4.34
Separator condition
Miscellaneous tab
The value given at this function is the efficiency rating of the dust separator element in the detector as a
percentage of the efficiency of a clean separator. A new element will give a reading of 99 in this function.
When the efficiency has decreased to 80%, the Fault indicator LED will illuminate, and the event log will show
“Separator renew”.
Note:
Fitting a new element will reset this figure to 99
4.35
Separator change date
Miscellaneous tab
This function defaults to “
--
“, which means that a separator fault will only appear when the efficiency
decreases to 80% (see 4.34, “Separator condition”). However, a date may be entered into
this function to allow
for a scheduled maintenance period. The detector will then generate a separator fault at the planned time
regardless of the condition of the separator, although degradation of the separator to below 80% efficiency
before this date will override this.
See section 11, “Maintenance” for further details.
4.36
Factory default
Miscellaneous tab
Enabling this function will reset each programmable function to the default value indicated in the text, where a
default setting is specified. It will also put the detector into FastLearn mode, regardless of whether or not Auto
Fastlearn is enabled (see Section 4.8). This ensures that the flow setups and alarm thresholds are optimised to
the detector’s working environment after resetting. It should be no
ted that where a ClassiFire alarm factor
other than the default is required for the protected area, this will need to be re-entered. Section 4.6 gives
details of the ClassiFire alarm factors.
