You can program and manage up to 1,000 users directly from the keypad, with no PC, software, or network connection required.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does \"Fail Secure\" mode mean for this door lock controller?\u003c\/h4\u003e\n\u003cp\u003eA: Fail Secure means that if power is interrupted, the door remains locked rather than unlocked. This is the preferred security mode for offices, server rooms, and any space where unauthorized access must be prevented even during a power outage.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use both a PIN code and RFID card together for added security?\u003c\/h4\u003e\n\u003cp\u003eA: Yes.
