Alarm system for KNX?

[Rasmus7700]

Hello Guys.
I'm trying to find a solution to implement a alarm system into my knx installation, where it's possible to enable/disable the alarm from a KNX touchpad.

I've seen that ABB has a solution, the L240 alarm panel, together with another module - but I can't read somewhere if it's possible to enable/disable the alarm from the KNX.

Another solution could be a Siemens SPC, but doesn't seems like they have any kind of KNX communication, only some serial for X-10??

What has you guys done?

Greetings

The real question is, if looking for an KNX alarmsystem or a KNX compatible alarmsystem?

Many alarmsystems give you the opportunity to program some pot.-free outputs, or inputs to turn on/off your device from KNX. A better, more
expensive
possibility are an KNX-Alarm interface, for example Telnot have such a interface.





On the other hand you can take a "real" KNX Alarm system, with this solution you can/must connect all sensors/reed-contacts to KNX-binary-inputs the complete system is based on KNX (GIRA 114200, ore the new ABB)

I was thinking something like a Alarm System with a KNX interface, with the opportunity to use wireless sensors, camreaes and all these things etc a Siemens SPC can do....

Yes, it's possible to use Binary signals, but I would like to read out status on the system and other things...


Hmm the new ABB, meaning the L240 alarm?

[greyowl]

Ah, no I mean the ABB "Vds Home" ore so.

(this is in German, I dont find a english one ;-)

I dont know the Siemens thing, at the last 5 projects i´ve connect with binary contacts (only for enable/disable the alarmsystem).

If the Siemens have no KNX-Interface, you probably could use a KNX-RS232 Interface (KNX Gateway seriell ? arcus-eds), ore a KNX-LAN Interface and a Gira HS.

[Rasmus7700]

Okay.. I will take a look on that...

Yes I was also wondering to make something with a RS232 connection to the alarm panel...
The Siemens has a RS232 X-10 interface - maybe that's possible?

I'm using the Smarthome/SmartVisu app for the control of my KNX installation

Hey Guys,

there is an KNX Gateway for the SIEMENS SPC. With bidirectional communication.
Sold at Faller SITEC: https://ch.spiap.com/partners/techno...r-knx-eib.html

or you can use KNXlogic: SPCX10 package: Siemens SPC to KNX | KNX & logic integration

Or telenot complex 400h with eib 400modul

macgyver, what module do you mean? I don't know what you're talking about.

We were about to buy the Faller module mhoetx refers to, but then we found the SPCway from KNXlogic , which only costs half of the Faller module.
It even has a richer feature set: it's also a KNX-IP router.

looking forward to test it when it arrives

Hey Guys,

the SPCway is looking quiet cool, but also very expensive.
I´m looking for a "lowcost" option or better a "no-cost" option. ;-)

There is a very interesting Swedish company called "Lundix". They designed and released a Web Gateway for the SPC Alarm System to handle Connections to 3rd party products and Building Automation Systems.
The API is using HTTP and REST principles (RESTful) for requests to SPC panel and WebSocket to reporting events from the SPC Panel.

And best of all, purchasing a license is only about 50$ !!!!

Here is a link to that Gateway: http://www.lundix.se/smarta-losningar/

Stay tuned!

Maybe that is the right stuff:

KNX compatible Approved alarm system

Hello forum.

Might I suggest the Alarm systems from KSenia Security which is a Italian based company. The standalone alarmsystems are mainly directed towards the residential market and therefore priced more reasonably compared to the more business / industrial market where the systems from ABB belong.

The KSenia Lares alarm system and components are all approved/certified which is important from an insurance company perspective. The system is 100% standalone but has a well thought through KNX compatible Gateway (with some area of improvement to come) but the overall solution offers tow way communication with a KNX system and group addresses are exported from ETS and into the gateway so KNX communication takes place on a group address level. Events from the alarm system are able to trigger events on the KNX bus/HomeServer/FacilityServer and vice versa.

Please feel free to contact me (Stockholm/Sweden) in case of any specific questions.

Kind regards Rolf

In the mean time I've installed the SPCway.
Here is some feedback:

the device works as expected and configuration was straightforward.
For me that's essential: when we work on a project, we don't want to spend time to figure out how to get something to work... time is ticking.

I spent something like 60 minutes to configure the device out of the box, including all groupaddresses for alarms, status and commands. That's for a building with 3 areas, 52 zones and 6 controlled doors with access control. I thinck that's good for a first time install. I did go through the install guide in preparation, but the web interface pretty much tells it all.

No surprises during testing.

I've measured the electrical consumption, and it was fluctuating around 1Watt.
@mhoeftx: Running a server or so, will consume much more. At 1EUR for 1WattYear, I don't want to suggest to run a 50W service/server.

One last thing: here we installed it on a new KNX project, so we needed a KNX-IP coupler. You get that (typical retail 300EUR for a decent one) for free in this spcway. We used it to connect ETS (v4) and do commisionning.


So for our customer, this is a good deal.
And we have a margin on the materials... and a happy customer.

So I'm happy

Hi,

If one accepts to have an alarm system relying on pieces of free software running on a linux box, Homewatcher is a solution. The requirements are:
- Python 3
- KNX opening or motion sensors, smoke detectors or any KNX device that exposes a boolean or float object that homewatcher will monitor.
- Linknx
- Homewatcher (which is a Python 3 package easily installable with pip)

The main features are:
- 100% configurable with an XML file
- as many operating modes as you want.
- as many types of alerts as needed: intrusion, fire, temperature, ...
- capability to execute any linknx action when an alert is raised, paused, resumed or stopped.
- a whole lot of things that are better documented in the wiki than I would paraphrase here...

I know people often argue that a handcrafted alarm system that runs on a PC is not reliable and as a consequence, useless. I agree it is definitely not as reliable as a built-in, ready-to-use alarm system, indeed. But it is way cheaper and easily configurable to suit any need. To me, it is a very interesting tradeoff to address maybe 80% of the needs.

Only my two cents,
Cyrille
