This is indicating a single break on the loop. Communication has to be
performed in both directions, to find all the units.
It might also be shown after a short circuit on the loop when short
circuit isolators are used (= communication in both directions).
(A double break will give the message: FAULT: No reply .....).
It can also be indicating a too long COM loop cable (i.e. all units are
not found until the communication is performed in both directions).
NOTE! Communication in both directions lasts for about ten minutes,
before a new attempt to communicate in one direction is performed. If
the break remains, a new ten minutes period starts, and so on. If the
fault is acknowledged and the break is corrected during a ten minutes
period, it will not disappear from the list until the end of the ten
minutes period.
FAULT:Cut-off input x,1580 board x,CU xx
(8 zones expansion board, DET8)
This is indicating a break or missing end of line resistor on input x
(zone line) on the 1580 board. A detector might have been removed
(stolen) from its base.
FAULT: Cut-off loop x, BS4 x, CU xx
(1584 Autronica interface board, BS4)
Cut-off (break) on the BS4 loop. This is indicating a single break on
the loop. Communication has to be performed in both directions, to
find all units.
th
Each 10 minute is an attempt made to comm. in one direction again.
