LRV Public Address Clause Samples
The LRV Public Address clause establishes requirements for the installation and operation of a public address system on Light Rail Vehicles (LRVs). Typically, this clause specifies the technical standards the system must meet, such as audibility, clarity, and integration with other onboard communication systems, and may outline responsibilities for maintenance and testing. Its core function is to ensure that important announcements and safety information can be effectively communicated to passengers, thereby enhancing safety and operational efficiency.
LRV Public Address. A. Provide an LRV PA subsystem which permits the Driver to make ad-hoc audible announcements throughout the Passenger area of the Train, and which provides predetermined automatic Stop/Station audible announcements that include the name of the next Stop/Station and Train destination.
B. PA volume shall be set to the configured parameter during vehicle start up. The interior volume shall be equipped with automatic gain control (AGC) with local sound sensing devices to maintain a clear and pleasing audio within the LRV considering interior noises.
C. The LRV-PA system shall allow authorized personnel to load and update automatic announcements.
D. The maximum noise levels of the LRV-PA system, when the Train, is stationary at a Stop or Station with all doors open, shall not exceed the requirements set within Section 1-2.
