Line Verification Panel with Key. New ASME A17.1-2010 code requires that the two-way communications means within the (elevator) car shall include a means to verify operability of the telephone line. When your local municipality adopts this new ASME A17.1 code the LV-1K can be added to fulfill all requirements for visual and audible signaling when it is determined the telephone line is not functioning. The LV-1K is essentially two products in one. First, it can be added to any new or existing Viking 1600A Series elevator emergency as a single phone stand alone solution. With the LV-1K installed, the 1600A Series phone will check the telephone line for dial tone on a daily basis. The LV-1K will provide an audible and visual indication when the telephone line is not functional. Second, it can be wired to a Viking model LC-6 six port concentrator, to provide visual and audible signaling for any grouping of elevators that are controlled by the same FIRE RECALL switch. The LC-6 not only allows 2 to 6 Viking elevator emergency phones share the same LV-1K Line Verification Panel, but it also allows the cost savings of those phones being able to share a single telephone line, and still meet all requirements of ASME A17.1. In accordance to ASME A17.1, the LV-1K has labeled ELEVATOR COMMUNICATION FAILURE in ¼in high red letters, and will sound an audible signal every 30 seconds and flash a red light when a telephone line fault is detected. Authorized personnel can silence the audible signal with the included key switch. The LED will remain flashing until the fault is corrected.
