3. Configuração e instalação
3.1 Montagem
The DK-12 keypad is designed for single-gang mounting. It can be installed using simple hand tools. Ensure the mounting surface is flat and secure. For indoor applications, standard electrical box mounting is suitable. For outdoor applications not directly exposed to rain or snow, consider using the optional WCC rain cover and WBB gasketed backbox for enhanced protection.

3.2 conexões elétricas
The DK-12 accepts 12V or 24 VAC/DC power input. Connect the power supply to the designated terminals on the circuit board. Ensure correct polarity for DC connections. The unit features a 5 Amp SPDT timed control relay output for connecting to a locking device (fail-secure or fail-safe configurable) and a Request to Exit (REX) input.
Refer to the wiring diagram on the back of the unit (Figure 2) for specific terminal assignments:
- +AC / -AC: Power input (12/24 VAC or DC).
- NC / COM / NO: Relay output for controlling the locking device.
- REF / REX: Request to Exit input.
Always disconnect power before making any wiring connections.
4. Instruções de operação
4.1 Programação de Códigos de Usuário
The DK-12 allows for easy programming of up to 99 user codes directly from the keypad. Specific programming steps are typically detailed in the quick start guide included with the product. Generally, programming involves entering a master code, followed by a command to add a new user code, and then the new user code itself.
The red, green, and yellow LEDs provide visual feedback during programming and operation:
- LED verde: Indicates successful code entry or system ready state.
- LED vermelho: Indicates an invalid code entry or error.
- LED amarelo: Indicates programming mode or other specific status.
4.2 Modo de Passagem
Passage mode allows the controlled access point to remain unlocked for a specified period, or until a specific command is entered. This is useful for periods of high traffic where continuous access is required without entering a code for each entry.
4.3 Modo de bloqueio
Lockout mode disables all user codes, preventing access through the keypad. This mode is typically activated for enhanced security during specific times or events.
4.4 Audible Keystroke Echo
The DK-12 features a configurable audible keystroke echo. This provides an audible confirmation for each key press. This feature can be enabled or disabled during programming to suit user preference.
5. Manutenção
The Securitron DK-12 keypad system requires minimal maintenance. Periodically inspect the keypad for any signs of wear or damage. Clean the surface with a soft, damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish or electronic components. Ensure all wiring connections remain secure.
6. Solução De Problemas
- Teclado não responde: Check power supply connections and ensure the unit is receiving the correct voltage (12/24 VAC/DC).
- Incorrect code entry not granting access: Verify that the user code is entered correctly. Check if the unit is in Lockout mode. Ensure the locking device is functioning properly.
- LEDs not illuminating: Confirm power supply. If power is present, contact technical support.
- O relé não está ativando: Check wiring to the locking device. Verify the relay output settings (fail-secure/fail-safe) and ensure the code is valid.
For persistent issues, refer to the full technical manual or contact Securitron technical support.
