Hi,
I bought the raspberry yesterday. It's fantastic!
I bought also a siren that I get sound through the raspberry ( show specifications https://www.dropbox.com/s/w7yx83gkwnanz ... n.png?dl=0 ).
The siren has a 12V1A power supply.
In the specs it says:
Trigger Low=Max.1VDC
Trigger High=Min.9VDC
Input Impedance(Alarm/Flash/Trigger) 1K ohm
Can someone kindly give me a scheme eletric to be able communicate with siren triggers?
I need a relay, is it a correct?
