RI-65-20

RI-65-20 is an onboard remote control panel designed for use in aircraft voice warning and annunciation systems. The unit provides centralized control of voice warning modules and manages the generation and routing of voice alerts to the flight crew.

The control panel operates as part of helicopter voice warning systems and controls RI-65-10 and RI-65-30 voice modules. It receives input signals from onboard sensors, including Almaz-UP and RI-65-B systems, and initiates corresponding voice warnings in response to abnormal or hazardous conditions.

RI-65-20 processes input signals in voltage or pulse form and transmits voice messages to the aircraft intercom system and radio communication channels. This ensures timely crew awareness of emergency and warning conditions during flight.

The unit is designed for reliable operation in harsh aviation environments, including exposure to vibration, temperature extremes, and electromagnetic interference. RI-65-20 is commonly installed on helicopters such as Mi-8 and Mi-17 and is widely used in conjunction with the Almaz-UP-48 voice playback unit.
