Figure 2: Manual cover indicating reference to the MT/41 Technical Manual for detailed system information.
- Connect the mains power supply (230V~ 50-60Hz) to the designated input terminals on the unit. Ensure proper grounding.
- Connect the system components (e.g., outdoor station, indoor monitors) to the 12V~ output terminals as per your system's wiring diagram.
- Double-check all connections before applying power.
3. Operating Instructions
The Comelit 1533 power supply operates automatically once correctly installed and powered. Its primary function is to convert mains voltage to the required low voltage for your intercom system.
- Upon applying mains power, the unit will provide continuous 12V~ power to the connected intercom or video intercom system.
- There are no user-adjustable controls on the power supply unit itself.
- System operation (e.g., answering calls, opening doors) is controlled by the connected intercom devices, not the power supply.
4. Maintenance and Care
The Comelit 1533 power supply is designed for long-term, reliable operation with minimal maintenance.
- Cleaning: Ensure the unit is disconnected from mains power before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or abrasive materials.
- Inspection: Periodically inspect the unit and its connections for any signs of damage, loose wiring, or overheating. If any issues are observed, disconnect power and contact a qualified technician.
- No User-Serviceable Parts: The unit contains no user-serviceable parts. Opening the casing will void the warranty and may expose you to dangerous voltages.
5. Troubleshooting
If your intercom or video intercom system is not functioning correctly, the power supply may be a contributing factor. Perform the following basic checks:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to intercom system |
