CSAM MandateCSAM Mandate 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.

The requirements of the system were defined by the AL3S* working group.

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)

CSAM SpecificationCSAM Specification

For the Fire Brigade Safety alarm acquisition from all CERN safety zones Local monitoring from each safety zone Central monitoring, archiving, display, reporting and configuration Non-interruptible 24h/365d system based on redundant networks Specific human computer interfaces and tools for the alarm handling Real-time monitoring of the correct functioning of all sub-systems.

For the Experiments and the other control rooms A safety alarm gateway to external systems A flexible system architecture for the integration of the LHC and LHC

experiments future alarms. A modular acquisition and local monitoring system based on

standard industrial equipment

Power supply, Location, server, display, acquisition module,etc.

INB compliant system based on redundant transmission paths.

Availability requirements 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. A supervision and monitors the availability of all sub-systems and

generates performance reports.
