Viking LSD-2 Smart Line Sharing Device with Inbound Switching Capability

Save on line leases while protecting critical communications with the Viking Electronics LSD-2 Line Sharing Device. Designed for alarm panels, emergency phones, intercoms and other priority devices, the LSD-2 lets you share an existing C.O. or analog PABX/KSU line without sacrificing reliability. Outbound calls from the priority port automatically take precedence, disconnecting non-priority calls briefly to return dial tone to the emergency device — ensuring lifesaving or alarm traffic always gets through. For inbound traffic, intelligent routing via Caller ID, Distinctive Ring or Quick Call Back directs priority calls to the correct device while non-critical calls flow to standard phones. The LSD-2 is TAA and NDAA compliant and built in the U.S., making it ideal for government, commercial security, surveillance and monitoring applications that demand dependable line management. Note that Caller ID is not passed through and single-line sites may require additional lines for concurrent emergency calls. Deploy the Viking LSD-2 to reduce costs and streamline your security communications — perfect for elevator phones, alarm systems, card readers and facility intercoms.
