hi there very sorry, forgot to ask, so i wire both units to the power supply twisting and connecting the +ve and -ve from each unit to the psu output, also connecting the -ve link from the 0v in the control panel, then twist the single tamper return from the units in the psu to the tamper return on the panel cable, and leave the 12v from the panel to psu disconnected.
also how would i wire the relay for the triggers thanks
