Preguntas frecuentes sobre manuais, rexistro e asistencia técnica para esta marca.
Most Blue Jay devices, such as the DCEM-96S and ALM series, support the standard Modbus-RTU protocol via an RS485 interface for remote monitoring and control.
For the ALM series annunciators, you can typically press the 'RSET' button on the front panel to reset the alarm relay output after the fault has been acknowledged or cleared.
Configuration menus on Blue Jay devices are often password-protected. Refer to your specific model's user manual (e.g., DCEM-96S or ELR-CH16) for the default entry code, which is frequently set to '0000' or '1000' depending on the firmware version.
