It is possible to use the Digital Keypad’s Hard Code function to lock out all User Codes. This will allow an individual to effectively lock out all other users. This function could be used for holidays, snow days, etc. to prevent entry. By entering the Hard Code all User Codes will be disabled until the Hard Code is reentered. The first thing that you must do is wire the Digital Keypad as shown below (this is in addition to wiring for power, locks, etc). You will then need to program at least one User Code and the Hard Code. While in the Program Mode you will also need to press in code 75. Code 75 will activate the Hard Code Toggle function. Please note that the Door Bell Function or any other function involving the programmable relay will not be available once this function is programmed.
