Setup
Mounting
The 212SE keypad is designed for surface mounting and can be installed directly onto a standard single-gang electrical box or most flat surfaces. Ensure the mounting surface is stable and secure to prevent tampering or damage. Use appropriate fasteners for the chosen surface.
Wiring
Connect the keypad to your access control system using the provided wiring harnesses. Refer to the detailed wiring diagram in the full installation guide for specific connections to power, relays, and tamper loops. Proper wiring is crucial for correct operation and safety. Always disconnect power before performing any wiring.
Operating Instructions
Basic Operation
To gain access, enter your assigned user code on the alpha-numeric keypad. The internal sounder will provide key press feedback, and the bi-color LED will indicate successful code entry and operation (e.g., green for access granted, red for access denied).
User Code Programming
The keypad supports up to 120 users. Programming new user codes or modifying existing ones requires entering a master programming code followed by specific key sequences. Consult the full programming manual for detailed steps on adding, deleting, or modifying user codes and relay functions. It is recommended to change the default master code immediately after installation.
Relay Control
The 4 on-board programmable timed relays can be configured to control various devices such as gates, doors, or lighting. Each relay can be set with specific activation times and conditions through the programming interface. Refer to the detailed programming instructions for relay configuration.
Maintenance
Cleaning
To clean the keypad, use a soft, damp cloth. Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the brushed metal finish, keypad components, and internal electronics. Ensure no liquid enters the keypad housing.
Inspection
Periodically inspect the keypad for any signs of physical damage, such as cracks or loose buttons, and ensure all wiring connections are secure. Verify that the mounting is still firm and that the keypad is not loose on its surface. Address any issues promptly to maintain optimal performance and security.
Troubleshooting
Keypad Not Responding
- Check power supply connections to ensure the keypad is receiving adequate power.
- Ensure all wiring is secure and correctly terminated according to the installation guide.
- Verify the keypad is within its specified operating temperature range (-20°F to 130°F).
Access Denied
- Confirm the entered code is correct and active. User codes can be deactivated or changed.
- Check if the user limit (120 users) has been exceeded, preventing new code acceptance.
- Inspect tamper loop functionality if enabled; a triggered tamper may prevent access.
LED Indicators
The bi-color LED provides status indications. Refer to the full manual for a complete list of LED indicator meanings, which can help diagnose specific issues or confirm operational status.
