fault in the unit.
FAULT: AAU xx, CU xx
AAU=1735 / 1736
The unit is programmed as another type of unit than the SSD says or
fault in the unit.
FAULT: Alarm input x, 1580 board x, CU xx
The zone line input x on the 1580 board placed in control unit xx
("master") is used for a single "slave" unit (control unit) or several
control units connected in parallel, i.e. the board is used for
"Redundancy in distributed system".
The input x is in "fire alarm state" but there is no activated fire alarm
in any control unit and no fault on the TLON Network. Check the
connections (e.g. of the alarm resistor) in the "slave" unit (units).
FAULT: Alarm input, tech.no. xxxxxx
The zone line input (Input 0) on the 3361 unit with technical number
xxxxxx is used for a single "slave" unit (control unit) or several
"slave" units connected in parallel, i.e. the unit is used for
"Redundancy in distributed system".
The Input 0 is in "fire alarm state" but there is no activated fire alarm
in any control unit and no fault on the TLON Network. Check the
connections (e.g. of the alarm resistor) in the "slave" unit (units).
FAULT: ASF COM-loop x, control unit xx
(ASF=2370, Addressable short circuit isolator)
This message is only shown when the control unit works in Sensitive
fault detection mode (menu H5/A2).
A short circuit, shorter / faster than the time delay for an ordinary
fault, has occurred on the COM loop. Can be used for commissioning
/ maintenance purposes.
