KP800 Master Code not being reset
A KP800 can have the Master code reset by powering down the unit, pressing the # key and powering up until the unit gives a long beep and the right hand side Green LED is lit.
The master code is then set to 1234
To enter programming mode press - 12341234 and the lED will turn orange to indicate you are in programming mode.
If the KP800 is set to greater than 4 digit PIN length then the master code reset to 1234 doesn't seem to work. The Master Code will be the same length as the user pin length e.g 5 PIN Length = Master Code 12345
