Rated at 20 watts output with a 25-volt line configuration, it bridges VoIP network infrastructure to analog 25-volt paging speaker systems. Installation is typically performed by low-voltage communications technicians or commercial electricians integrating IP-based paging into facilities. The unit ships as a single piece (each) and is categorized as a power amplifier within the Valcom product line.\u003c\/p\u003e\u003cp\u003eThe VIP-851-25 is suited for commercial and institutional paging applications where an existing 25-volt speaker network needs to be driven from a SIP-compatible IP communications platform. Typical installations include office buildings, schools, warehouses, and healthcare facilities upgrading from analog paging to VoIP-based systems. The 20-watt output capacity supports distributed speaker loads common in these environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSIP gateway functionality bridges IP network to 25-volt analog speaker lines\u003c\/li\u003e\n\u003cli\u003e20-watt power amplifier output for distributed paging speaker systems\u003c\/li\u003e\n\u003cli\u003e25-volt line output compatible with standard commercial paging speaker wiring\u003c\/li\u003e\n\u003cli\u003eSingle-unit packaging suitable for individual zone or system deployments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or integration component for commercial 25-volt distributed paging and intercom systems utilizing SIP-based IP communications infrastructure.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified low-voltage technician or licensed communications contractor familiar with VoIP paging systems and NEC low-voltage wiring requirements. De-energize all connected speaker circuits and disconnect network power before servicing or replacing the unit. Verify SIP network settings and 25-volt speaker load impedance before bringing the system online. Follow the manufacturer documentation for SIP registration and audio output configuration.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Power\u003c\/strong\u003e: 20 watts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLine Voltage\u003c\/strong\u003e: 25 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category\u003c\/strong\u003e: Power Amplifiers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALCOM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: VIP-851-25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALCOM","offers":[{"title":"Default Title","offer_id":51563023171890,"sku":"VIP-851-25","price":1502.03,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9617b64c75b24b5402b077063e605fac.jpg?v=1786488312","url":"https:\/\/voomisupply.com\/products\/valcom-vip-851-25-sip-gateway-power-amplifier-20w","provider":"Voomi Supply","version":"1.0","type":"link"}
