Disarming Alarm KNX

[Canha]

Hi Cytech

I\'ve integrated a Home Automation KNX with the Cytech system. I\'m trying to use it (Home Automation KNX) to arm and disarm the comfort alarm.

The arming I can do it and it\'s easy (using the \"arm to away\" on the \"KNX to Comfort\" tab), but I can\'t disarm through KNX. I\'ve seen that it can be done using actions, responses and counters, but is an easy way to disarm the alarm through KNX?

Thanks

Using response is pretty simple.
You need to map a knx group to a counter and the counter to a response.
In response, you can disarm the Comfort.
Read the user manual of Comfigurator and UCM/KNX carefully. It contains all stuffs you need.

Also the forum topic http://www.comfortforums.com/forum12/1797.html shows an example of using a KNX touchscreen  to show a keypad which can be used to disarm the security system  by entering the user code

Hi Slychiu and TheMax74

I´m using a very basic touch panel (Zennio Z38i), and i can\'t introduce user code. I can only use KNX objects (1bit, 1byte, etc) to arm and disarm.
I\'ve already tried to use the conter, and then the response, but every time I press it, weard things happens on the Keypad from Comfort.

After the counter, on the response I use the action \"Security=> SecurityOff\".

Is this enough for disarming?

Thanks people

Hi Canha,

I think what Slychiu\'s trying to say is to create keypad buttons (0 - 9 and Enter keys) on your Zennio Z38i.

All these 11 buttons (0, 1, 2, 3, 4, 6, 7, 8, 9, 0, Enter) will have the same KNX group address say 0/0/11 (1 byte).
For button 0, program it to send the value 0.
For button 1, program it to send the value 1.
.
.
.
For button 9, program it to send the value 9.
And For button Enter, program it to send the value 26.
All the above are done in Zennio Z38i.

At Comfort\'s end, map the group address 0/0/11 as a \'Keypad Key\' type under KNX to Comfort configuration page; see the attached image.
Don\'t forget to click \"Write to EEPROM\" afterward.

This way when you want to disarm Comfort system, simply enter your sign-in code on your Zennio Z38i and press Enter.
If the code you\'ve entered here matches the valid sign-in code in Comfort then the system will be disarmed.
Also, it is more secure compared to just pressing a button on KNX switch to disarm the system.

Hi Hendy

I\'ve alredy tried what you write on the post. But I think that you don\'t know the Zennio Z38i touch panel.
This is a very basic touch panel. It only has 12 free functions, divided by two Menus with 6 in each one, whitch one of them can be restricted by an internal password. In this menu (restricted by an internal password) I have the 5 possible alarms (4 arming and 1 disarmig). So I need a disarming funtion that only needs one press button.
I\'ve tried to use a Group Adress, using a Counter, then activating the Response, that runs an action \"Security=> SecurityOff\". But it\'s not working fine.

Any ideas?

Thanks for the help

You\'re right. I\'m not familiar with the Zennio Z38i touch panel.

Have you mapped the group address to a Counter number on the KNX to Comfort configuration page?
Write it to the EEPROM?

What value do you send when that disarm button is pressed?
Then in the respective Counter response try the following actions:

If LastUcmCounter = (the value that disarm button sent)
    KeyswitchArm SecurityOff
End If

Hi Hendy

I\'ll try it as you said, and i\'ll tell something later.

Meanwhile, i\'ll show you what I\'ve done and please tell me if you find any error that I may be doing.

Thanks

Remove the IF statement, leave only \"KeySwitchArm SecurityOff\" and try again

Hi people

I\'ve tried to disarm the alarm trough KNX as I said before but unsucessful.

I\'m using a telegram comming from the KNX, and it activates a counter, and then a response.

When I activate the response manualy (i.e. through the Comfort software) it works fine. What i\'ve noticed is that even if I try to use anoter response and it doesn\'t work.

Do I have to do something to activate the response using counters?

Thanks
