(on the LCD)
Possible Reasons
Correction
CHECK : Fan -x-
All 3- way valves were shortly
closed.
1. Check position of 3-way
valves
2. Switch-over to stand-by fan
aggregate
Fuse(s) of fan aggregate on
power supply module defect
Correct faults
Exchange fuse
Fan -x- defect
Exchange fan
CHECK : Valves and Fans
All 3- way valves in wrong
position.
Set 3- way valves in air
sampling position
Both fan aggregates are defect. Repair or exchange fan
aggregates
FAULT : Airflow Line -x-
3- way valve in wrong position. Check position of 3- way
valve
Detection line is clogged.
Send compressed air through
detection line. Ensure all 3- way
valves are closed in way to
smoke detection panel during
this procedure
FAULT : Data Transfer Device -
x-
Defective fuse in device -x-.
1. Eliminate fault
2. Exchange fuse
Note: The correlation of the
Device address no. of device -x-
is not correctly adjusted.
Adjust correct device address
no. (refer to section 6 )
different “device“ nos. to the
system components is listed on the
Cable connection to device -x-
(RS-485-Bus) is incorrect
Check cable connection
rear side of the door of the smoke
detection panel
Device -x- is defective
Replace device -x-
only fire alarm panel:
FAULT : Data Transfer

FAULT : Smoke Detector Line -
x-
Smoke detector -x- is not
installed.
Insert smoke detector
Smoke detector is defective.
Change smoke detector
FIRE : Line -x-
(but smoke cannot be verified)
ID no. x is attached to more
than one smoke detector
Change ID nos. of smoke
detector to correct setting
( refer to 5.3.2 )
After cleaning the smoke
detector, the labyrinth has not
been correctly reassembled.
Ensure, that the snapping lugs
