Can anbody shed some light on this problem please? I have 2 zones showing 65528 Ohms resistance, one is not used (1004) and programmed as spare the other (1015) is set as a RF zone. The panel is a Galaxy g2-20. Thanks.
Sorry, I don't know much about alarms, but a bit about electronics!
That value sounds suspiciously close to an over-range value on a 16bit ADC - so I would suspect that 65k Ohm isn't the true resistance value, but your (1015) zone is open circuit.
But, I may be wrong and will defer to higher powers!
