CSAM 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 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

CSAM Specification, cont.

• No common mode of failure
• 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.

Experiments DCS

• How
• Data exchange protocol
• JCOP conventions
• For the XCR operators
• Only Safety Alarms and safety-related information
  concerning their experiment.
• Also analogue values of safety equipment.
• Possible seamless integration in the experiment
