Newest demands for high end security systems are going to more availability and cluster computing. Both demands are fulfilled with the new technology system TITAN SBI von TITAN electronic. SBI (Security Bus Interface) is a high speed, high availability ring bus system with a special protocol to fulfil the following main requirements:

Cluster Computing

Central or sub-central units are not fix connected to sensors and actors


Fulfills the latest requirements of encryption of data

Quality of Service

Uses existing resources efficiently and ensures the required level of service

Load Balancing between Server

Distributes high volumes of load across multiple servers in a network in order to deliver speed and performance

Message and Command Prioritisation

Maintaining all neccessary messages and commands in emergency

Routing Capability between Networks

Part of the network with routing capability even between the rings

Hardware Implementation

Highest demands on quality in every technology used

Free Scalability

Updating with more clients easily

The demand of cluster computing in the security means that the central or sub-central units are not fix connected to the sensors and actors. So that means the sensors and actors have to be connected to a network device which sends their current messages and states to a cluster computing network. In that cluster there are some computers, SUB-Central database and logic to decide who is computing the result of that sensor message. The decision is normally made according to the load balancing rules. The system is free scalable, because in case of more sensors the cluster can be updated accordingly with more computers. The new SBI ring technology also fulfils the latest requirements of encryption of their data on the ring and is fully build up in hardware with wire speed capability. The whole protocol stack is down in hardware and not in software. In case of larger systems the SBI technology provides multi SBI-Rings. Each of them is a part of a big network with routing capability between the rings. The SBI-Ring can also be used for transportation of data from one RS485 to another RS485 device.

Common Systems

Common Solution

In the left picture a common solution of an intrusion detection or access control system is shown. A sub-central (intrusion detection central) is connected on one side to a server and on the other to direct connected sensors/actors. Additional sensors/actors can be connected through a data bus system. The sensor states will be computed in the sub-central and activates some actors (siren etc.) accordingly. Over an IP network the data computed states can be transported to a security management system like TITAN control for live monitoring of an operator.

Common Solution - Failures

That solution can have four major failures:

1. Central-Failure
If the sub-central does not work the whole system is not working.

2. Network-Failure
In case of a network failure the security management system does not get alarms and system messages. The operator gets no information about the system and from the security side, the system is not full working.

3. Data Bus Failure
In case of data bus failure the system recognizes that situation, brings an alarm to the operator, but the sensors and actors are not working.

4. Sensor Line Failure
In case of sensor line failure only that specific sensor is not working. The system will send a specific message to the operator for further actions.

TITAN SBI Solution

TITAN SBI Solution

The TITAN SBI Ring solution consists of one or more sub-centrals and one or more remote input output devices(RIO´s). Each of the sub-centrals is connected via IP network to a central server. The sub-centrals and the RIO´s are connected via SBI-Ring. Each RIO has all necessary interfaces to connect the field sensors/actors and data equipment (like card reader). The RIO transports the states and commands via the SBI-Ring to/from the sub-centrals. One of the sub-centrals compute the sensor date and send back some commands to actors or to a data equipment device.

TITAN SBI Solution - Failures

That solution can have also four major failures:

1. Central-Failure
In case of sub-central failure the system works without any problems, because the remaining working sub-centrals will do the job.

2. Network-Failure
In case of IP network failure the system work also without any problems, because the remaining working sub-centrals have still connection to the server.

3. SBI-Ring Failure
In case of SBI-Ring failure the system automatically isolates the failure and switch to a bus operation. The system also works, but from the performance side the bus is slower than the ring.

4. Sensor Line Failure
In case of sensor line failure the system works like the common solution.

RIO Modules

RIO Modules

The remote input output module is the main name of an SBI-Ring device. Each RIO consists of an electronic board with the following interfaces: 1x SBI-Ring Interface 6x Analogue Inputs 3x Relay Outputs (monitored) 1x RS422/485 Interface 1x Backup Battery Input 1x Interface to Extended RIO-Board 3x NTS-Sensor Inputs All that interfaces and their functionality gives the RIO the chance to be used for an access control door interface (card reader, door contact and electrical strike) and also for an intrusion detection system. In the intrusion detection usage the inputs can be used for connecting the sensors and the 3 relay outputs can be used for sirens, lamps and locking strikes in doors. The RIO is coming in mounting box for on wall and flush mounting installations. The board provides the installer with easy to use connectors for fast and long-time installations.

RIO Modules Failures

The SBI-Ring cable includes both the data and the power line. In a failure situation there can be one or both lines are defect. The power line is a bidirectional line. From each side of the ring the power can be supplied. In case of short circuit the each RIO disconnect the short circuit with his build-in insolation circuit. In case there is no power from both sides the RIO can also be equipped with a backup battery. In that case the system will run also on a 2 point power failure. Additional to the power line the data line can also have are failure. In that case the system will automatically isolate that failure from the two neighbour RIO´s. The RIO electronic has two isolation circuits for each of his neighbours (see figure 3). One insulator is for the power and one for the data line. In the normal situation the insulator is deactivated as shown in figure 3. Figure 4 shows an activated power and data line insulator.

TITAN SBI Topology

TITAN SBI Topology

In bigger solutions it is necessary to combine multiple SBI-Rings to one network. Each RIO has is one unique address in the whole network. The routing RIO´s (blue RIO´s) have up to 4 SBI-Rings and can route data packets from one ring to the next. All the routing goes in wire speed, because of the special patent pending hardware solution.
