1. Introducció
The SCS Sentinel AAA0009 Dry Contact Electric Relay is designed to facilitate the integration of intercom systems with motorized gate or door openers. This 12V relay converts the output signal from an audio or video intercom's opening button into a dry contact signal, enabling the activation of a gate motor or similar automated system. It provides a reliable and robust solution for power automation control in residential or professional settings.
2. Producte acabatview
The AAA0009 relay features a compact design with a transparent orange casing, allowing for visual inspection of its internal components. It is equipped with four terminals (pods) for electrical connections, designed for easy integration into existing systems.

The relay operates on a 12V input, making it compatible with standard intercom power supplies. Its primary function is to provide a momentary dry contact closure, which is ideal for triggering gate motor control boards that require a simple switch input.
3. Configuració i instal·lació
Proper installation is crucial for the safe and effective operation of the relay. It is recommended that installation be performed by a qualified professional if you are unfamiliar with electrical wiring.
3.1 Esquema de cablejat

Refer to Figure 2 for a visual representation of the wiring connections. The diagram illustrates the connection of the relay between an intercom system and a motorized gate.
3.2 Passos de connexió
- Intercom Connection: Connect the two output wires from your intercom's gate opening button (typically a 12V signal) to terminals A1 i A2 on the SCS Sentinel AAA0009 relay. These terminals represent the 12V coil input for the relay. Ensure correct polarity if specified by your intercom system.
- Gate Motor Connection: Identify the dry contact input terminals on your gate motor's control board. These are typically labeled for external push-button or key-switch activation.
- Relay Output to Gate Motor: Connect the relay's dry contact output terminals (typically 11 i 14 for normally open, or 12 i 11 for normally closed, depending on your gate motor's requirement) to the corresponding input terminals on your gate motor control board. The diagram shows connections to terminals 12 i 14, indicating a normally open contact configuration.
- Verificació de potència: Once all connections are secure, apply power to the intercom system and the gate motor.
Important: Always disconnect power to all devices before performing any wiring to prevent electrical shock or damage to equipment. Consult the manuals for your intercom and gate motor for specific wiring requirements.
4. Instruccions de funcionament
Once the SCS Sentinel AAA0009 Dry Contact Electric Relay is correctly installed and wired, its operation is automatic and integrated with your intercom system.
- When a visitor calls via the intercom, communicate as usual.
- To open the gate or door, press the designated opening button on your intercom unit.
- The intercom's 12V output will energize the relay coil (A1-A2), causing the relay's internal contacts (e.g., 12-14) to close momentarily.
- This momentary closure acts as a signal to your gate motor control board, initiating the gate opening sequence.
5. Manteniment
The SCS Sentinel AAA0009 Dry Contact Electric Relay is designed for long-term, reliable operation with minimal maintenance. However, periodic checks can help ensure continued performance:
- Inspecció visual: Periodically inspect the relay and its connections for any signs of physical damage, corrosion, or loose wiring.
- Integritat de la connexió: Ensure all wire connections remain tight and secure. Loose connections can lead to intermittent operation or electrical issues.
- Condicions ambientals: Ensure the relay is installed in a dry environment, protected from extreme temperatures and direct moisture, unless specifically rated for outdoor use.
6. Solució De Problemes
If you experience issues with your SCS Sentinel AAA0009 Dry Contact Electric Relay, consider the following troubleshooting steps:
- Gate Does Not Open:
- Verify that the intercom's opening button is functioning correctly and sending a 12V signal.
- Check the wiring between the intercom and the relay's A1/A2 terminals for continuity and secure connection.
- Listen for an audible click from the relay when the intercom button is pressed. If no click is heard, the relay may not be receiving power or may be faulty.
- Check the wiring between the relay's dry contacts (e.g., 12-14) and the gate motor control board. Ensure these connections are secure and correctly wired to the gate motor's input.
- Confirm that the gate motor itself is powered and operational independently of the relay.
- Funcionament intermitent:
- Inspeccioneu tot el cablejat per detectar connexions soltes o aïllament danyat.
- Ensure the 12V power supply from the intercom is stable and not fluctuating.
Avís: Do not attempt to repair internal components of the relay. If the unit is faulty, replace it with a new one.
