Hva betyr feilkoden?
The central electronic module (CEM) monitors the alarm siren with control messages. The code is set when the siren or its control module has registered an internal component fault. The alarm may then stop working, and a yellow warning symbol may appear in the display.
Mulige årsaker
- Internal fault in the alarm siren control module (SCM)
- Internal fault in the alarm siren (BBS)
Hva du kan gjøre

- 2If the code does not return, the fault is probably intermittent, and it is enough to follow up the next time the alarm is used
- 3Check that the alarm fuse is intact
- 4Look for loose or corroded connectors at the siren
- 5Have a workshop with diagnostic equipment check the siren and replace it if the fault returns
