Security module zone contacts

Darkwing shared this question 7 years ago
Need Answer

Hi,


I have the security module and have 3 zones in use hardwired to COM and Z1 to Z3. I now came up with the idea to create a doorbell using one of the remaining NC zones. So I take a simple push button which has a NC switch, and make a rule that whenever this gets activated, my siren makes a chime sound.


This works great.


Now my question:


This pushbutton has a build in light, and it would be nice if it works so people can see it in the dark. This however means I need to connect 8 - 12v to it, and those wires would be in parallel to the NC wires connect to the zone contacts. Would a voltage over these contacts damage the security module in a way?


Thanks

I presume so. Can you not find any info on the Security module NC contacts voltage type?

these switches are not connected to a power source, they are monitored so when a connected device opens or closes a contact it acts on this change. So I bet putting an outside powersource on these will fry something inside :-P

If you really want to do this you can do it with a Qubino Flush 1d relay but you would need to have a 12 v power source for the contact and 24vdc or 120 vac power source to feed the module. You can probably get away with it if you install a 24 vdc power source to power the module and a voltage regulator to 12 vdc which you can use to power the contact. I did an integration for an outdoor siren which uses 12 vdc, so I used 120 vac to feed the 12 vdc power supply and module and use the 12 vdc to feed the contact.


Those security modules usually work with 0v I also thing that you will fry the contacts on the module. Or at least they won't last for long since they are not designed to switch under voltage load.

Thanks, I'll try that!

You just need to use a extra 12v relay.

trigger the relay whit the switch en connect the NC contact from the relay the security module.
