BS 5839 Button
This button has been added for when there is significant cause and effect programmed into the
system but the outputs need to meet BS5839 specification.
FIG 29
This means that when selected and a Callpoint is activated, the sounders will operate within the 3
seconds required by BS overriding any sounder cause and effect. However, the remaining cause and
effect for output devices will only follow when the time to process this is available.
Local Zones ?
Generally UK networks use global zones where all zones for the whole network appear on all panels.
In this case if a shared zone on 2 panels were put into test then the zone would be in test on both
panels.
Most European networks would not be configured in this way for example on a 3 panel network
Panel 1 would have 1-5 zones, panel 2 would have 6- 10 zones and panel 3 would have 11-13 zones.
This feature has been added so that when selected local zones are displayed on the panel screen.
