8. Questions and Answers
Question 1: If our facility has front and back doors, both use S2-MF readers, how can we use front
door card to open back door?
Answer: If you want to make a single card to open front and back door, you must add this very card to
both front and back door reader.
Question 2: Could front door infrared control unit use to program back door reader?
Answer: Yes, but the front door infrared control unit must input correct Master Code stored in back
door reader.
Question 3: If add front door card using User ID at front door reader, and add a different back
door card using same User ID at back door reader, since the two different cards use the same User
ID, can they use to open both front and back door?
Answer: No, you cannot. Because reader is stored the card number as valid code to open door, different
cards have different card number, although they have the same User ID, they still cannot use
interchangeably to open the door.
Question 4: Could another company use their S2-MF infrared control unit to program our reader?
Answer: Yes, as long as they know your reader's Master Code. So it is better changing the reader's default
Master Code to prevent this situation.
Question 5: What if I add a single card to a reader twice?
Answer: The reader will reject and use beeps to warn you.
