6. 21 March 2001JCOP presentation - L. Scibile and the CSAM Team5 CSAM Mandate u The CSAM will provide CERN with an integrated safety alarm system covering acquisition, transmission, logging and display for all the CERN sites, the LHC machine, LHC experiments and experimental areas. The system will be incorporated into the safety, technical, accelerator, and experiment control rooms. u The requirements of the system were defined by the AL3S* working group. u The mandate of the project team covers the system specification, prototyping, tendering, installation and integration of the product in the existing monitoring architecture. * Safety alarms require the immediate intervention of the fire brigade and are defined at CERN as 'Alarms of Level 3' (AL3S)

7. 21 March 2001JCOP presentation - L. Scibile and the CSAM Team6 CSAM Specification u For the Fire Brigade u Safety alarm acquisition from all CERN safety zones u Local monitoring from each safety zone u Central monitoring, archiving, display, reporting and configuration u Non-interruptible 24h/365d system based on redundant networks u Specific human computer interfaces and tools for the alarm handling u Real-time monitoring of the correct functioning of all sub-systems. u For the Experiments and the other control rooms u A safety alarm gateway to external systems u A flexible system architecture for the integration of the LHC and LHC experiments future alarms. u A modular acquisition and local monitoring system based on standard industrial equipment

8. 21 March 2001JCOP presentation - L. Scibile and the CSAM Team7 CSAM Specification, cont. u No common mode of failure u Power supply, Location, server, display, acquisition module,etc. u INB compliant system based on redundant transmission paths. u Availability requirements u In order to meet the availability requirements of  99.8% set by the AL3 Working Group, a Safety Integrity Level (SIL) 2 has been fixed. u A supervision and monitors the availability of all sub-systems and generates performance reports.
