Other remote software features

Reset
If latching alarms (see Section 4.16) or latching faults (see Section 4.17) are enabled, the relevant alarm or fault
warnings will remain on the detector front panel LED’s and controlling unit until a reset is performed. If using
SenseNET software, individual detec-tors can be reset (refer to the SenseNET User Guide for details). In the
remote software, a global reset is available which resets all detectors on the SenseNET loop, or a single stand-
alone detector.
To perform a reset, either select the menu options “Options Global Reset” or click
the symbol indicated below.
Histogram screen
The histogram screen shows various aspects of the detector function. To enter the histogram screen, either
select the menu options “View > Histogram viewer…” or click the symbol indicated below.
The following screen appears:
There are two types of smoke density histogram; one shown in blue (the “fast” histogram) which updates every
15 minutes, feeding information to the long-
term “slow” histograms (which appear in yellow). These set the
detector sensitivity based on the ambient smoke conditions and it takes 24 hours for the two slow histograms
(the “day” and the “night” histograms) to complete their learning phase.
