The latest alarm-reporting trend is in Voice-Over Internet Protocol (VoIP), which is continuing to replace traditional telco services. Napco’s NetLink UL-listed TCP/IP central station receiver is part of the company’s growing family of NetLink alarm reporting products. The UL864/UL1610-listed NetLink receiver is rack-mounted, enabling cost-effective, secure Internet alarm reporting. In full compliance with UL central station applications requiring primary and mirrored backup receivers, two NetLink UL receivers can be installed at the same cost as a single traditional receiver. Both NetLink TCP/IP UL receivers interface with conventional central station automation systems and are simply connected to each other with a network crossover cable, where the secondary mirrored receiver serves as a hot backup, duplicate receiver.
