Page 8: Introduction
International Regulations for Preventing Collisions at Sea, 1972. The system works by listening and detecting the direction of a fog horn. The Alphatron SSRS system is always listening for sounds on the outside of the ship and will only playback and display sounds once a horn has been detected. The ship's own horn can be suppressed by closing a closing contact on the Alphatron SSRS system, which will disable detection for the duration it is held closed. - Page 9 Figure 3: Sound Reception System 9 | Introduction...

Page 14: Operation
2.1.1 Normal Mode When the Alphatron SSRS is first started it will start in the normal mode. When in this mode the unit will idle until a horn signal is detected. Detected horns are audible from the speaker and indicate the direction of the source of the signal. -
Page 15: Manual Listening Mode
2.1.2 Manual Listening Mode Figure 13: Selecting the Fore Microphone Figure 14: Selecting the Aft Microphone In the manual mode each of the four microphones can be listened to individually. In this mode the sound from the active microphone is audible through the speaker at all times. To activate the manual listening mode, perform the following actions: 1. -
