• Drill pilot holes and secure the backplate to the wall using appropriate screws and anchors.
• Route necessary wiring through the wall opening to the keypad's connection points.
• Attach the keypad securely to the backplate.

3.2 Wiring

Refer to the wiring diagram provided with your product packaging for specific connections. General wiring considerations include:

• Connect power supply wires (typically 12-24V AC/DC) to the designated power input terminals.
• Connect the two Form C relay outputs to the controlled devices (e.g., electric strike, magnetic lock, automatic door opener).
• Connect egress devices (e.g., exit buttons) to the egress inputs.
• Connect a door sensor (e.g., magnetic contact) to the door sensor input.
• Ensure all connections are secure and insulated to prevent short circuits.

After wiring, apply power and observe the status LEDs for initial power-on indications.

4. Operating

The SK-2323-SDQ keypad is operated by entering user codes or programming new settings directly through the keypad interface.

4.1 Initial Programming

Upon first power-up, the keypad will typically be in a default programming mode or require a master code to be set. Consult the full programming guide for detailed steps on setting the master code and initial system parameters.

4.2 Adding/Deleting Users

To add a new user, enter the master code followed by the programming sequence for adding users, then input the desired user code. To delete a user, follow the corresponding programming sequence and enter the user code to be removed.

4.3 Accessing Controlled Devices

Users can gain access by entering their valid user code on the keypad. Upon successful code entry, the corresponding relay output will activate for the programmed duration, unlocking the door or activating the connected device.

4.4 Doorbell Function

If Output #2 is programmed for doorbell functionality, pressing a specific key or sequence on the keypad will activate a connected doorbell chime.

5. Maintenance

The SECO-LARM SK-2323-SDQ is designed for durability and requires minimal maintenance. Regular checks can help ensure long-term reliability.

• Cleaning: Wipe the keypad surface with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish or keypad buttons.
• Inspection: Periodically inspect the keypad for any signs of physical damage, loose connections, or wear.
• Functionality Test: Regularly test user codes and egress buttons to ensure all functions are operating correctly.
• Power Supply: Ensure the power supply is stable and within the specified voltage range.

6. Troubleshooting

If you encounter issues with your SK-2323-SDQ keypad, refer to the following common troubleshooting steps:

• Keypad Unresponsive: Check the power supply connection. Ensure the keypad is receiving adequate power.
• Codes Not Working: Verify that the user codes are correctly programmed. Ensure the master code is correct if attempting programming. Check for any tamper alarms that might disable the keypad.
• Door Not Unlocking: Check the wiring to the electric strike or lock. Ensure the relay output is activating (listen for a click or observe status LEDs). Verify the lock mechanism is not jammed.
• LEDs Not Illuminating: Check power supply. If only specific LEDs are off, consult the full manual for diagnostic codes.
• Tamper Alarm: If the tamper alarm is active, ensure the keypad is securely mounted and the optical tamper sensor is not obstructed or triggered.

For persistent issues, consult the complete product manual or contact technical support.
