Connecting to a FACP or BMS Requiring one single Trouble or Fault indication
It is recognised that in some applications the user may not wish to, or may not be able to, accept
numerous inputs due to the number of inputs available to them on their Fire Alarm Control Panel
(FACP), or building management system (BMS).
In such cases, outputs from the FireVu system are completely flexible and can be altered so that a
trouble or fault state from any of the detectors will trigger the same relay contact.
Regions Web-page
The FireVu detector is capable of providing up to 16 detection regions, and as shipped each view is
split into the maximum 16 as a 4 x 4 grid.
However, should the specific detector view to be monitored require it, these regions can be altered.
They are in fact, fully configurable as to the number used, (1 to 16), their placement, their size, and
how much of the detector’s view they actually cover.
The act of breaking the detector’s view down i
nto multiple regions provides a high degree of
flexibility and the ability to customise each and every detector’s view to provide a highly robust
detection with minimal false alarm risk.
There are three main benefits achieved with this method:
1.
Areas with
in the detector’s view which may cause false alarms, have visible steam or smoke
present as part of a manufacturing or other process, or are simply not of interest can be
excluded from the active analysis of FireVu’s algorithms simply by not covering those
areas
with a region.
2.
Regions can be sized and positioned so as to cover similar areas within each field of view,
this may prove useful if needing to filter out non-smoke phenomena using the colour
filtering tool.
