3. Setup and Installation
Proper installation is crucial for the optimal performance and security of your Secukey XK3-BT system. It is recommended that installation be performed by a qualified technician.
3.1 Power Supply Connection
The unit requires a power input of 12-28 Volts AC or DC. Ensure the power supply meets these specifications and is stable. Connect the power wires to the designated terminals on the unit. Refer to the wiring diagram provided with the product packaging for specific terminal identification.
3.2 Wiring for Door Control
The XK3-BT features an internal relay for controlling an electric lock. Connect the lock to the NO (Normally Open), NC (Normally Closed), and COM (Common) terminals as required by your lock type. An exit button can be connected to the designated terminals to allow egress from the secured area.
3.3 Wiegand Interface
The Wiegand In & Out connections (26-37 bits) allow the XK3-BT to function as part of a larger access control system or to transfer user data between units. Consult your system integrator for Wiegand integration details.
3.4 Mounting
Mount the unit securely on a flat surface at an appropriate height for user access. Ensure the mounting location is free from excessive vibration and direct exposure to extreme weather conditions, despite its IP66 rating, to prolong its lifespan.
4. Operating Instructions
4.1 Access Modes
The Secukey XK3-BT offers multiple ways to grant access:
- RFID Card: Present a registered 125 Khz EM/Hid card to the reader area.
- PIN Code: Enter a registered PIN code on the keypad.
- Card + PIN: Requires both a registered card and its associated PIN for enhanced security.
- Multiple Cards/PINs: Allows for sequential presentation of multiple credentials for access.
- Smartphone (Bluetooth App): Use the dedicated Secukey app on your smartphone to unlock the door via Bluetooth.
