on another diy mission got an haes 4zone fire alarm looking inside looks like only zone 1 and 2 been used however b4 I start to install just checking it .i bought some 4k7 resistors put them in but one and two still show faults and also under the mains light there is a amber light ( psu) which also is on ( think this may be due to no batts but not sure ). And I get a remote signal activated fault light does anyone know how to program signal to off thanks
