Dusting off the BS8521 Protocol
The British Standard BS8521:2009 was prepared as a request from purchasers and users of social care alarm systems to establish a common signalling protocol and compatibility between device manufacturers and Alarm Receiving Centres. The idea was good, but in practice most devices continued to communicate with the ARCs through already established and in many cases proprietary care protocols.
Today, many Alarm Receiving Centres have implemented support for BS8521:2009, although not widely known. In the years to come the new IP based protocols SCAIP and NOW-IP* will be the de facto standards.
What if your Alarm Receiving Centre only supports the analogue version of BS8521, but you want to connect digital devices? Would it be possible to establish a communication bridge between new digital units and legacy ARCs running BS8521:2009?
Seamless bridging between old and new worlds
Our serverless and cloud based Alarmbridge can handle both analogue and IP based protocols and make seamless bridging between the analogue and digital worlds. For example, a SCAIP alarm can easily be bridged into an analogue BS8521 alarm but bridging the alarm communication is not all! In like manner VoIP calls can be bridged with analogue voice calls to establish direct connection between users and alarm centre agents, and vice versa.
Below is a practical example of how digital devices, with or without SCAIP, can be incorporated into modern solutions and communicate with existing Alarm Receiving Centres that support legacy protocols.
