Why should alerting occur over IP?
Because the transfer in the core network of the telecommunications company currently already occurs via IP and the transformation of analogue signals to digital signals necessary for this can lead to problems in the alarm transmission.
Because telecommunications companies will no longer support analogue data or alarm transfers in the short or long term. This service will already be canceled in Switzerland as of 31.12.2017.
What is a firewall and what is its significance for the alarm transmission via IP?
The firewall is an object designed to protect the IT infrastructure from unauthorized access from the Internet.
For this, rules can be set up in the firewall, allowing specific IP addresses to have access to the IT infrastructure or the Internet via specific ports.
In order for an alarm to be transferred, the corresponding rights need to be alloted to the communicating device in the firewall.
Comparison of stabilities of a digital connection via IP and an analogue connection
Because of their infrastructure, analogue networks guarantee an availability rate close to 100%. The general availability of IP networks is globally very good and the micro cuts go unnoticed by users in standard use. For alarm applications requiring a high availability rate, it is necessary to transmit via two transmission channels (IP and GPRS for example). By choosing this transmitter category, the availability approaches that of analogue networks.
Is it possible to configure transmitters with static and dynamic IP addresses?
All Sitasys IP transmitters support dynamic addressing (DHCP) and static mode. This choice is made when configuring the transmitter. It is possible to change your mind and reconfigure the transmitter at any time. Note that if the transmitter is in service, the transmission tests have to be performed again.
What are the criteria for selecting a transmitter?
The choice has to be made based on the requirements of the object to protect and the desired degree of safety. The EN5050131 European standard defines 4 safety levels with particular requirements for each. For a grade 1 system, a single-channel transmitter is sufficient, whereas a grade 4 installation requires a minimum of a level 3 dual-channel transmitter. All Sitasys transmitters (link on the ipTNA page) are dual path and level 3. Do not hesitate to contact us for more information.
When should a dual path transmitter be used?
Only dual-channel transmitters can guarantee rates above 98% without requiring investments in an IT infrastructure with high investment and maintenance costs in order to guarantee the required availability for your alarm solution. During maintenance work on routers or firewalls for example, the GPRS path guarantees the availability of the system.
Remote configuration and firmware update
Sitasys regularly updates the transmitter’s software (firmware). It is recommended that you regularly install these updates. This installation can be performed on site or remotely, which avoids having to go on-site for this operation. The transmitter remains functional during the transmission of the firmware and a protection mechanism allows for restarting the transmitter to the last functional version in case of communication interruption or error (file corruption). Similarly, it is possible to remotely configure the transmitter with our mobile applications. More info >
Proprietary versus standard protocol
The data exchanged between the transmitter and the alarm station can be based on manufacturer protocols (proprietary) or be transmitter using open and standard protocols such as DC09 or TS50136-9. There are arguments in favor of both possibilities but the interoperability between systems lends an advantage to open protocols. Do not hesitate to contact us to obtain further information or assistance in making a choice based on your needs.
Critical elements to monitor
Fixed and mobile net provider
Today, it is almost impossible to know the path followed by transmitted data through the web or telecommunications network. In order to avoid a “single point of failure”, we recommend you choose 2 different companies for the fixed and mobile networks.
What do EN50136, EN50518 or EN54-21 mean?
There are several standards (local, European and worldwide) in the field of alarm transmissions. The EN50136 European standard describes alarm transmissions for intrusions. On the other hand, the EN54-21 standard describes the transmission of fire alarms. The alarm reception stations are controlled by the EN50518 European standard. Each of these standards contains the description of the transmission chain and the requirements towards performances.
Sitasys employs experts working in various standardization committees. Since the world of standards is complex, do not hesitate to contact us if you desire more ample information.
