FAULT: No reply, Expansion Board x, loop x, Control Unit xx
This is valid for the I/O Matrix board (4582) no. x, connected on
COM loop x in the Control Unit no. xx.
Check the board's address, i.e. the I/O Matrix board no.
•
(Jumpers JP1, JP2 and JP3 on the board).
Check if the board is disconnected from the loop.
•
Note: In 19" rack systems, the 4582 circuit is integrated in the new fan
/ damper (1206/1211) and zone (1205) modules
FAULT: No reply, alert annunciation unit xx, Control Unit xx
FAULT: No reply, external presentation unit xx, Control Unit xx
Alert Annunciation Unit
External Presentation Unit
Display unit 5054
The contact with the unit is interrupted. Check the cable, all
connections, etc. Is correct / complete SSD downloaded (via
EBLWin)? Check the address and SW mode settings.
FAULT: No reply Loop unit xxxxxx
The unit (e.g. a customized unit), cannot be found by the Control
Unit.
Check the unit's COM loop address (with the programming
•
tool 4414).
•
Check the downloaded Site Specific Data (SSD).
The unit might be faulty.
•
The unit might be removed from the COM loop.
•
There might be a double break or short-circuit on the COM loop.
•
FAULT: No reply zone: xxx address: xx
technical number xxxxxx
The unit cannot be found by the Control Unit.
Check the unit's COM loop address (with the programming
•
tool 4414).
Check the downloaded Site Specific Data (SSD).
•
The unit might be faulty.
•
The detector may be removed from its base.
•
There may be a double break or short circuit on the COM
•
loop.
Valid for a wireless smoke detector 4611: Battery voltage <
•
2.3 V or the Base station (4620) does not receive any detector
data.
FAULT: Read/write site data (SSW), Control Unit xx
SSW = the data that is changed during operation, i.e. week average
sensor values, access codes, calibration values and event logs, in
control unit no. xx.
If the C.U. was powered down (i.e. mains and battery
•
disconnected) without first doing a Safe shut down of control
unit via menu H8/S6 (see page 158), this fault might be
generated when the C.U. is powered again. After fault
acknowledge the SSW will get default values and the fault will
be corrected (serviced). Supervised outputs have to be
calibrated via menu H5/A1.
Some external influence has caused a fault in the SSW. This is
•
very serious. Call for service personnel/engineer.
