Hva betyr feilkoden?
When the alarm is armed, the central module checks the siren at regular intervals. If it gets no answer despite several attempts, the fault is logged, and the siren may then give a false alarm. The cause may be a break in the signal wire, a blown fuse or an internal fault in the siren.
Mulige årsaker
- Open circuit in the signal wire to the siren
- Blown fuse

- 3Follow the wire to the siren for breaks and chafing, and repair as needed
