I installed this alarm,28 to 30 yrs ago,,worked perfectly,changed battery a couple of times,but this time,on taking cover off,I inadvertently did not enter code to silence sounder,and proceeded to change battery,and replaced cover,but alarm would not reset.,,,I have noticed on an internet engineers manual for this alarm,Guardall Rascal,,that by putting a link in the ###, on control board,this will put the system back to factory settings,,my question is,,after winding down the system,and putting this link in,,( I have no idea yet,how and where this link is on the board),,would doing this will the system stop sounding and showing alarms,and then allowing me to proceed with set up procedure in manual,,thank you.
