Viking LSR-1 One-Line Seizure Relay

Save on dedicated line costs while ensuring emergency communications always get priority. The Viking Electronics LSR-1 one-line seizure relay (phone line concentrator) lets emergency call stations seize a shared analog CO or PABX line, interrupting any active call and returning a fresh dial tone so emergency calls connect immediately. Designed for security and surveillance environments, the LSR-1 supports 12–32 V DC power operation and ships with a 12 V DC adapter for quick setup. Modular RJ-style connections simplify installation in electrical box or standalone mount applications, and during power outages the device automatically routes the line directly to the emergency device to maintain monitoring and alarm functionality. With NDAA and TAA compliance and a 2-year limited warranty, the LSR-1 is suited for campuses, parking facilities, healthcare sites and government installations where reliable emergency call routing and networked security are critical. Deploy the Viking LSR-1 to reduce recurring costs and improve emergency response reliability—contact your sales rep or add to your next security systems order.
