- Mounting: Choose a suitable location for the monitor, typically near the entrance or in a central area. Securely mount the monitor bracket to the wall using appropriate screws and anchors.
- Wiring: Connect the monitor to the intercom system using either twisted pair or coaxial cable, as per your system's requirements. Refer to your system's wiring diagram for specific terminal connections. Ensure all connections are secure and correctly polarized. The coiled cable with telephone connectors should be connected to the handset and the monitor base.
- Power Connection: Once all wiring is complete and verified, reconnect the power supply to the intercom system.
- Initial Test: Test the monitor's functionality by initiating a call from the outdoor unit and checking video and audio transmission.
Note: Incorrect wiring can damage the device or the intercom system. If you are unsure about any step, consult a qualified technician.
4. Operating Instructions
Familiarize yourself with the monitor's controls for effective use:
- Receiving a Call: When a visitor initiates a call from the outdoor unit, the monitor will ring and display the video feed. Lift the handset to answer the call.
- Door Opening: Press the dedicated door opening button (often marked with a key icon) to unlock the entrance door.
- Auto-Ignition: Use the auto-ignition button to manually activate the video feed from the outdoor unit without an incoming call. This allows you to view the entrance area at any time.
- Auxiliary Functions: The auxiliary button can be programmed for various functions depending on your intercom system configuration (e.g., activating an additional light, opening a second gate). Refer to your system's main unit manual for specific auxiliary functions.
- Contrast and Brightness Adjustment: Use the dedicated controls (usually dials or buttons on the side or bottom of the monitor) to adjust the display's contrast and brightness to your preferred viewing level.
- Call Exclusion LED: The signal LED will illuminate to indicate that the call exclusion function is active, meaning incoming calls will not ring on this monitor.
5. Maintenance
To ensure the longevity and optimal performance of your Legrand Tegui Intercom Monitor, follow these simple maintenance guidelines:
- Cleaning: Gently wipe the monitor screen and casing with a soft, dry, lint-free cloth. For stubborn marks, slightly dampen the cloth with water. Avoid using abrasive cleaners, solvents, or chemical sprays, as these can damage the surface.
- Dust Removal: Regularly dust the monitor, especially around ventilation openings, to prevent dust buildup that could affect performance.
- Cable Inspection: Periodically check the coiled handset cable and other connection cables for any signs of wear, fraying, or damage. Replace damaged cables immediately.
