Fermax Placa Marine Ref. 1455 Installer Manual

1 DESCRIPTION

The Fermax Placa Marine Ref. 1455 is a video door entry system with the following components:

• Altavoz (Speaker): For audio output.
• Cámara (Camera): 1.2Mpx high-definition camera with illumination for night vision.
• Estado de la red LAN (LAN Status): Indicates if the LAN network is available (lights up if no LAN is available).
• Pantalla TFT de 4.3" (4.3" TFT Display): Touchscreen interface.
• Teclado de marcación (Dialing Keypad): For entering numbers and commands.

Up to 8 smartphones can receive calls simultaneously. It's also possible to make simultaneous calls to various MEET devices and/or third-party SIP devices using SIP protocol.

A CSV file with device information must be imported to the plate.

CSV File Generation and Import Procedure:

1. Select EXPORTAR (Export) to generate a blank CSV table and save it to your PC. Rename the file or use the default name (e.g., MEET CALL DIVERT PXXX-YY.csv).
2. Open the CSV file with Microsoft Excel.
3. Cell A1 should contain "APARTMENT, NAME,". Do not modify.
4. Use subsequent cells (A2, A3, etc.) to enter device data for call forwarding. The format depends on the call type:
   • FERMAX MEET LICENSE: APARTMENT, sip:XXXXXXX@sip.fermax.com (XXXXXXX is the license number).
   • MEET device in the same installation: APARTMENT, sip:XXX@IP_DEVICE (XXX is device identifier, IP_DEVICE is the monitor's IP).
   • Third-party SIP device (via SIP server): APARTMENT, sip:username@IP_SIP_SERVER (username is the SIP server registration, IP_SIP_SERVER is the SIP server IP).
   • Multiple forwarding formats can be assigned to the same apartment using different rows in the same column.
5. Save the completed table and upload it to the plate by clicking “Seleccionar archivo” (Select file), locating the CSV, and clicking “IMPORTAR” (Import). A message “EXPORTACIÓN EXITOSA” (EXPORT SUCCESSFUL) will appear.

Example:

Note on Non-Latin Languages: For non-Latin languages (e.g., Chinese, Russian, Arabic, Hebrew), export a blank CSV, open with Notepad, copy the directory list in the desired script, save as .CSV (UTF-8), and import via the web server. Do not use Microsoft Excel for non-Latin scripts to avoid formatting issues.
