Hi guys I have a problem with this Doorbell. I use an external power supply and I wire it like this:

power supply +positive ----> Striker +
power supply -negative ----> Com1
No1 ----> Stiker -

when I do this connection and basically any other connection ( I tried all combinations) I dont get any Voltage (on multimeter) or strike when i hit the door unlock button. Is my unit broken or what ? Is there any setting i should do to make it work ?

Ps. also tried to measure the continuity instead of having a load and nothing comes off, just an open loop

thanks
