4. Installation
The SCS Sentinel Orion 32068 system utilizes a 2-wire connection for simplified installation. Follow these steps carefully.
4.1. Planning the Installation
- Location: Choose suitable locations for both the indoor and outdoor units. The outdoor unit should be easily accessible to visitors and protected from direct heavy rain if possible. The indoor unit should be placed where it is convenient to answer calls.
- Wiring Path: Plan the shortest and most protected path for the 2-wire cable between the indoor and outdoor units.
- Power Supply: The indoor unit requires a 220V AC power supply. Ensure an accessible power outlet or junction box is available.

- Mounting: Secure the outdoor unit to a flat, vertical surface using the provided screws and wall plugs. Ensure it is mounted at an appropriate height for visitors.
- Wiring: Connect the two wires from the indoor unit to the designated terminals on the outdoor unit. Refer to the wiring diagram provided with the unit for specific terminal identification.
- Nameplate: Open the nameplate cover and insert your name or house number. The nameplate is backlit for visibility in low light conditions.
4.3. Indoor Unit Installation

- Mounting: Attach the mounting bracket of the indoor unit to an interior wall using screws.
- Wiring: Connect the two wires from the outdoor unit to the corresponding terminals on the indoor unit. Also, connect the 220V AC power supply to the designated power input terminals.
- Handset Placement: Secure the indoor handset onto its base.
4.4. Door Release Wiring (Optional)
The indoor unit includes a button to open an electric strike or lock. The system provides a 12V DC output for this function.
- Compatibility: Ensure your electric strike or lock is compatible with a 12V DC signal. Many older gate locks operate on AC power. If your lock requires AC, a relay will be necessary to convert the DC signal from the intercom to an AC signal for the lock. Consult a qualified electrician for this modification.
- Connection: Connect the electric strike/lock to the designated terminals on the indoor unit.
5. Operating Instructions

- Receiving a Call: When a visitor presses the call button on the outdoor unit, the indoor handset will ring. Lift the handset to establish two-way audio communication.
- Speaking to Visitor: Speak clearly into the handset. The visitor will hear you through the outdoor unit's speaker, and you will hear them through the handset's earpiece.
- Opening the Door/Gate: During a call, press the dedicated door release button on the indoor handset to activate the connected electric strike or lock.
- Ending the Call: Replace the handset on its base to end the conversation.
6. Maintenance
- Cleaning: Clean the indoor and outdoor units with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check the wiring connections for any signs of wear or damage. Ensure the outdoor unit's nameplate is clean and legible.
- No User Serviceable Parts: Do not attempt to open or repair the units yourself. Refer all servicing to qualified personnel.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to indoor unit | Power supply disconnected; faulty wiring. | Check power connection; verify wiring. |
| No audio (indoor/outdoor) | Loose wiring; damaged unit. | Check 2-wire connections; contact support if issue persists. |
| Door/gate does not open | Incorrect wiring to electric lock; incompatible lock type (AC vs DC); faulty lock. | Verify lock wiring and compatibility (12V DC output from intercom); test lock independently. If AC lock, install a relay. |
