Screen 1 displays various levels associated with the 6100 power supplies.
Figure 7.23 Typically Panel Diagnostic data screen 1
Screen 2 displays the levels read from the Auxiliary 24V, Firelink End of Line Monitoring and
conventional alarm circuits. The numbers in brackets are internal data.
Figure 7.24 Panel Diagnostic data screen 1 ( showing typical values )
Screen 3 displays levels associated with the loop driver circuits.
The ‘missed scans’ and ‘seen scans’ numbers may be used to determine the integrity of the loop
communications by comparing how many ‘good’ scans versus how many ‘bad’ scans have been
detected since the counters were reset ( 20 minutes of detection time is given until the counters reach
the end value ).
