Since 1st November 2014, the standard required to obtain a PSA license has been PSA 33:2014. This standard includes the non-technical requirements for licensing (e.g. Tax Clearance, Insurance, Staff Selection etc.) and makes reference to the technical standards required. The standard is available free of charge from the PSA and EQA websites (link). The technical standards required for new entrants are EN 50518 and SR 25. ARC’s which were licensed prior to 31st October may continue with certification to IS 228 and SR25 for an interim period. All ARC’s need to prepare a contingency plan as per section 11 of EN 50518-2 (independent of whether certification is to EN 50518 or IS 228).
EN 50518 is broken into 3 parts, however, all sections are interdependent, it is not possible to obtain certification to one part of EN 50518 independent of the other sections.
SR 25 (“Alarm Receiving Centres Alarm – Handling Procedures”) is primarily focused on reducing false alarms. This is now a mandatory requirement for all ARC’s (it was not a specific PSA requirement prior to 1st November 2014).
