Comfort Automation/ Security System Forums

Hello and first of all, scuse me for my bad english.

I don\'t know if this is the right place in this forum, but i have a question about installing and configuring the external siren.

Well, my external siren, has an internal backup battery, a 12v+ cable, a - cable, 2 tamper cables and a cable normally disconnected. When an alarm occours, this cable must be connected to a - and then, the siren play the sound.

How can i connect it to comfort?

If i connect it in \'reverse mode\', i suppose it works fine, but i think it always uses the backup internal battery to play the sound, so i think it is not a good idea.
Do you have any suggestion?


Thank you

Figure 2.5 in the Installation Manual shows the siren connections for a self actuated siren https://www.cytech.biz/installation_manu...ory_id=106

The diagram is also shown below

I know the diagram about siren connection, but i suppose my siren need a different way to connect.

My siren has 3 cables:
red and black cable, need to be continuosly connected to 12v + -.
green cable, needs to be normally disconnected and when an alarm occours, it must be connected to the -.

So, how can i connect these 3 cables?

Your siren does not need a special way to connect at all. The diagram above applies to it
In the diagram above, there is a 12V and Com on the siren which must be connected to Comfoort 12V and Com
There is a Negative trigger on the siren which is connected to SRN-. When an alarm occurs the SRN- is pulled to 0V and triggers the siren

Ok, thank you very much.
