  The CERN Safe­ty Alarm Mon­i­tor­ing sys­tem ac­quires safe­ty alarms and safe­ty in­for­ma­tion gen­er­at­ed by CERN safe­ty equip­ment such as fire and gas de­tec­tors, evac­u­a­tion, emer­gen­cy stops and other safe­ty re­lat­ed sys­tems, which are lo­cat­ed in both sur­face and un­der­ground areas of CERN sites and ac­cel­er­a­tors. Cur­rent­ly there are 22170 alarms from 1025 safe­ty equip­ments. This in­for­ma­tion is trans­mit­ted in a high pri­or­i­ty and di­verse­ly re­dun­dant way to the CERN Safe­ty Con­trol Room for im­me­di­ate in­ter­ven­tion of the CERN Fire Brigade. The sys­tem was de­signed based on two main stan­dards, the EN 50136 and IEC 61508 and was com­mis­sioned in 2003. In 2009 it was de­cid­ed to launch a con­sol­i­da­tion pro­ject in order to up­grade both hard­ware and soft­ware. The con­sol­i­da­tion pro­ject in­cludes de­ploy­ment of a pri­vate CERN wide fiber optic TCP/IP net­work for the trans­mis­sion of safe­ty alarms, an up­grade of the SCADA soft­ware, a database up­grade and the re­place­ment of all com­put­ers. In this paper the sys­tem is pre­sent­ed, the on­go­ing con­sol­i­dat­ing work is de­tailed and the mid­dle and long term im­prove­ment plans for the sys­tem are de­scribed.
