Thanks James I cant work it out... I started rigging the panel up at home to see if they would work before I posted here ....4K7 resistor in parallel across alarm terminals and and 2K2 in series across tamper. So blue from panel in to 1st alarm terminal at pir, 4K7 resistor across alarm terminal, 2K2 from alarm terminal in to tamper, from other tamper terminal to panel. programmed as double EOL but comes up as active when checking zone status? any ideas?
