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 t o fulfill all requirements for visual and audible signaling when it is determined the telephone line is not functioning.
The LV-1K is essentially three products in one. First, it can be added to any new or existing Viking 1600A Series elevator emeency as a single phone stand alone solution. With the LV-1K installed, the 1600A Series phone will check the telephone line for actual dial tone on a daily basis. The LV-1K also continuously monitors for loss of Talk Battery voltage and will immediatel y provide an audible and visual indication when the telephone line has been accidentally cut or disconnected.
Second, it can be wired to a Viking model LC-6 six port concentrator, to provide visual and audible signaling for any grouping of elevato 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 telep hone line, and still meet all requirements of ASME A17.1. Third, since the LV-1K continuously watches for loss of Talk Battery voltage, it can be used to provide an audible and visual indication when any analog station or telephone line has been accide ntally cut or disconnected from any telecom device.
In accordance to ASME A17.1, the LV-1K is labeled "ELEVATOR COMMUNICATION FAILURE" in 1/4" high red letters, and will sound an audible signal every 30 seconds and flash a red light when a telepho 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.
