Configuring the universal sensor

[Ace02 2]

I'm working on integrating my Jablotron alarm system to the HC2 with a Fibaro universal sensor.. My setup is pretty much as the one on the attached picture.

The alarm can be programmed to switch PGX and PGY output to GND when activated. In my case PGY is switched to GND when the system is armed and PGX when the alarm is activated.

Since the universal sensor needs an input (not gnd) this is done through 2 small 12v relays. I have measured the voltage on the 2 outputs and everything works as expected.

My problem is, that the universal sensor does not react to any of the inputs. I have tried different setting under the advanced menu but still without success..

Could anybody help me getting this to work?

Ace02, inputs of UBS react on GND signal, not the high state. Does the UBS react in interface when you manually connect IN connectors to GND?

Okay that helped a bit.. The sensor works, but somehow it does not recognise the GND on the PGX terminal.. If i connect the IN wires to the common GND in the system they react as supposed...

If I meassure the voltage between the positive and the pgX (when switched) everything is fine..

Any clue??

just measure it

use a multimeter to see wich pins on the relais you need

you need also a ground from uni sensor connected to that relais

if you don't know what you are doing, ask someone to do it for you

Ace02, on your diagram pgmX connectors are not marked as internally connected, so i suppose that are relay outputs, right? Make sure about this and if so attach free GND wire from UBS to one connector and input to another. Or consult electrician or some kind of installer.
