Multiple fault signals for cut of
line (s)
Ø
C
ould happens that, in case of the cut of
the line, it will be activated the output of
address 1 and also other following
outputs in first instance and further
communication error signals; in this
case refer to chapter 9 «Display
messages for event» to check where
this event is present.
Ø
In case on the Control Panel is present
or recorded the situation of all the
detectors together in fault condition, and
on the display of the Controller is shown
the message of “Normal Operation” , it is
possible that happens a temporary short
circuit on the line. In this case verify the
absorption of the system Controller –
Detectors; If the value of absorption are
the ones shown in technical information
it means that no one socket has gone on
protection. If the protection has been
activated or the short circuit is still
present, the absorption of the line will be
superior of around 200 mA respect to the
normal operation ones.
Ø
The short circuits on the loop configured
line and isolated by the socket, are
displayed on the controller and the
activation of the fault output of zone 1
(ex. IsoTx:----5---, IsoRx:-----6--). The
isolated socket, keep on the open line up
to the reset of the controller by switching
off and on the power supply. If after the
reset the signal is still present it means
that the short circuit has not been
solved.
