Without seeing the cct I am moved to ask why you powered it with AC when the instructions required DC. Would you put diesel in a petrol car & expect it to run ?

It has an Idiot Diode in series with its DC input jack. The diode will rectify 12VAC and produce 16VDC in pulses.

It turns on a relay when it sees the light turn on of the cell phone.
