PSS-1 CSAM2: CERN Safety Alarm Monitoring

The CSAM monitors the CERN Safety Equipment (CSE) distributed throughout the organization’s surface buildings, accelerator and experimental sites and ensures transmission of Alarms-of-level-3 to the CERN Fire Brigade, as well technical alarms to the CCC.

PSS-2 Building access control

Following the end-of-life and end of after-sales support from the manufacturer, the access control hardware and software of the EVOLYNX brand will be replaced.

PSS-3 Access biometry

The access points of the LHC, SPS and PS accelerators are equipped with biometric systems to strengthen authentication that is, positively validate the identification of each person entering the area.

PSS-4 Evacuation with Voice Alarm

The Audible Emergency Evacuation System for the LHC machine and underground experiment and AWAKE is essential to Personnel Safety.

PSS-5 LHC Gas/ODH Detection

ALARMS: Fire detection, ODH

PSS-6 Operational Dosimeter (DMC)

Following the initial HSE-RP request from 2016, accelerator access systems shall check that the Operational Dosimeter is with the person accessing and is active.

PSS-7 LHC Personnel Protection System

The LHC Personnel Protection System (PPS) consists of two components, the LHC Access Control System (LACS) and the LHC Access Safety System (LASS).

PSS-8 LHC Fire Detection

The system, installed at the LHC construction time (2007), assures automatic smoke detection in areas with a significant amount of combustible material/equipment and/or ignition sources.

PSS-9 LHC SNIFFER

The SNIFFER system is a combined air-sampling fire and gas detection system specially developed for the LHC Experiments. The SNIFFER system is essential to personnel safety and asset protection – classified as Level-3 alarm.

PSS-10 SPS Site Security Gates

The SPS security gates are the entry points to the fenced area of the SPS BA buildings.

PSS-11 BA7 Fire Safety

Following a renovation of the fire safety installations of points BA1 to BA6 in SPS during LS2 (2019-2020) it is necessary to consolidate the fire safety systems in BA7 to achieve the equivalent level of protection in this area.

PSS-12 PS Personnel Protection System

PSS-13 PS CTF3 Sea Containers Consolidation

The access to the CTF complex was installed in 2015 inside sea containers as temporary solution. After review with HSE-RP, the project was descoped and it is proposed to remove the one of two sea containers hosting the CTF3 complex access points.

PSS-14 Distributed Temperature Sensing by Optical Fibre

PSS-15 LHC Safety Cable Tray

Installation of new safety cable tray in LHC tunnel.
