- Page 4 Fault Finding of Airflow Faults Fault Indication: “FAULT Airflow all lines” or “FAULT: Airflow Line -x-y-z-“ • Ensure one of the fans is running. • Ensure 3-way-valves are open. • Ensure upper door of the smoke detection panel / extension unit is closed.
- Page 5 Table 1a and 1b • If the measured voltages are correct, but fault indication is still present, the detector interface module must be exchanged. • If the measured voltages are not correct compared with table 1, disconnect the wires at the terminal nos. 33/34 at the detector interface module. Measure the...
- Page 6 Fault Finding of Data Transfer Faults General Information The following components of the smoke detection system SDS are connected by a 4- wire-bus ( RS485-bus ): Name of Component Function Address – No. Indication- / control module Master No address...
- Page 7 Fault Indication “FAULT: Data Transfer” This fault indication without display of any device no. appears only on the repeater panel. It means, that no call of the master reaches the controller of the indication- / control module in the repeater panel. Therefore no other faults can be displayed.
- Page 8 Fault Indication “FAULT: Data Transfer Device -1-2-3- ... ” ( all connected components are indicated as faulty ) When the fault indication lists all addressable components, please check the following: • Check setting of rotary switch at indication- / control module in smoke detection panel.
- Page 9 Fault Finding of Smoke Detector Faults General Information Max. 6 smoke detectors are connected to one smoke detection panel or to one extension unit. Each smoke detector has a DIP-switch on its rear side to assign its ID- no. Note that only the values 1 – 6 are allowed ( also in the extension units with higher line nos.
- Page 10 All smoke detectors of the smoke detection panel or extension unit indicate “FIRE”, but no smoke is present Please disconnect the wires at terminal nos. 31/32 at the detector interface module. If the alarm indication is still present, the detector interface module is defective and must be exchanged.

- Page 12 Clean both parts of labyrinth with compressed air. Ensure, that the small white reflector in the optical chamber is clean. If there are sticky residues, the labyrinth may be cleaned with a mild soap solution or with isopropyl alcohol.
- Page 13 Problems with Fuses on Power Supply Module (SDS-2/6) Blown Possible Reason Fuse Power supply module defective. Exchange power supply module. External short circuit on the bus cable. Please disconnect bus cable from terminal nos. 17, 18, 19 and 20 at the power supply module and start system again.
