Possible Cause
Repair Action
Main circuit <device> "-"
There is a negative line to
earth fault on the indicated
device (NAC1; 24V-A output
circuit; dial-up alarm; dialer
FWRE )dial up connection
failure); batteries' charger; a
loop; or the annunciator
panel
Find the source of the fault
–damaged wire or a water
leak – and fix it.
Main circuit <device> "+"
There is a positive line to
earth fault line on the
designated device (NAC1;
24V-A output circuit; dial-up
alarm; dialer FWRE (dial up
failure); battery charger; or
loop
Find the source of the fault
–damaged wire or a water
leak – and fix it.
Main circuit <device>
limited current
The current has been limited
on the designated device
(AC1N; 24V-A output circuit;
dial-up alarm; dialer FWRE
dial up connection failure);
battery charger; or a loop
Find the source of the fault
–damaged wire or a water
leak – and fix it.
Main circuit <device> low
voltage
The voltage is low on the
designated device (AC1N;
24V-A output circuit; dial-up
alarm; dialer FWRE )dial up
connection failure); battery
charger; circuit loop; 3V
battery backup or batteries
If the device is the battery or
backup battery (3V): replace
the battery or backup
battery (R2032C).
Control panel fault – send to
the manufacturer for repairs
Main circuit <device>
disconnect
The designated device is
disconnected (NAC1; 24V-A
output circuit; dial-up alarm;
dialer FWRE )dial up
connection failure)
Check line continuity and
connect an end of line
resistor (5.1KΩ) at the
output circuit connectors.
Main circuit <device> short
There is a short circuit on
the designated device
(NAC1; 24V-A output circuit;
dial-up alarm; dialer FWRE
)dial up connection failure)
battery charger; or loop
Find the cause of the short
circuit and remove it
Main circuit <device>
exists, not programmed
The designated device (the
annunciator panel; detector;
button; or an input or output
module) is present in the
system, but it has not been
defined as yet.
