Question 2684 Deck General

The correct answer is B) be used instead of the public address system. The regulations for a general alarm system on a towing vessel require that it have a flashing red light in areas with high background noise (A), have a contact maker at the operating station (C), and be capable of notifying persons in any accommodation, work space, and the engine room (D). However, the general alarm system is not required to be used instead of the public address system, as the two systems serve different functions and can be used in conjunction. The other options are incorrect because they do not match the specific requirement that the general alarm system not be used instead of the public address system.
