does anyone have an engineer code for scantronic 9800 alarm?
i have an rt code flashing on my keypad and understand i need an engineers code to remove it. does nayone know the code or roughly how much this is going to cost to sort out?
check that display is showing alarm condition.
if showing "rr" press clear twice.
key in 0, followed by engineers code default (7890)followed by 99 .
display should go blank and day LED will light.
