Digital Social Alarm Protocol - Guidance


As Communications Providers continue to migrate towards All IP networks, they are increasingly converging voice traffic onto their IP infrastructures which may have an adverse impact on the reliability of in-call, analogue tone based protocols.

The impact differs per region but is increasing across the UK. In addition, cellular technology is increasingly used next to broadband and optical fibre solutions.

This guidance is designed to be used in conjunction with the Technical Specification 50134‑9 which defines the IP communications protocol for social alarms, optimised for communication between stand-alone hybrid or digital alarms and Alarm Receiving Centres. ]

This Technical Specification can be purchased from the BSi on the following link:

This guidance has been produced by TSA Special Interest Group 10 (Digital Interoperability) and is designed to accompany the UK implementation standards of Technical Specification 50134‑9 which was approved by CENELEC (European Committee for Electrotechnical Standardisation) on 28th May 2018.

Further information regarding TSA Special Interest Group 10 can be found on the following link:

Neither this guidance nor the Technical Specification include all the necessary provisions of a contract and compliance with both the Technical Specification and this accompanying guidance cannot confer immunity from legal obligations.
