The main goals of a Detector Safety System (DSS) for the experiments at the LHC are to protect the experiment, with that the investment into it, and to avoid situations leading to Alarms-of-Level-3 in order to increase the running time of the experiment. It should complement and not duplicate existing systems, such as the Detector Control System (DCS) and the CERN Safety System (CSS).
The alarms are managed by the LHCb DSS Piquet (Tel: 16 80 00).

The failures, interventions and maintenance are listed in the DSS logbook.
A 'Common Experiment System piquet service' (CES piquet, Tel: 16 20 82) can be called 24h/24 in case of a hardware problem on the DSU racks.
