{"product_id":"toa-n-8640sb","title":"TOA N-8640SB IP Door Station Custom Install Sub-Station Board Kit","description":"\u003cp\u003eThe TOA N-8640SB is a sub-station component kit designed for systems integrators and AV installation professionals who need to embed IP intercom functionality into a custom enclosure or operation panel. It contains the internal PC board and mechanical parts of the N-8640DS IP Door Station, minus the front panel, giving integrators full control over the physical form factor while retaining the full electronic capability of the N-8000 Series IP intercom platform.\u003c\/p\u003e\u003cp\u003eThis kit suits access control integrations, building automation projects, and permanent installed-sound environments where off-the-shelf door station enclosures do not fit the architectural or operational requirements. The board connects to an IP network via a standard RJ45 port and draws power through PoE (IEEE 802.3af), eliminating the need for a separate power run in most installations. An optional AC adapter provides an alternative power path where PoE infrastructure is not available.\u003c\/p\u003e\u003cp\u003eAudio performance is built around a hands-free full-duplex circuit with a 300 Hz to 7 kHz speech range and 16 kHz voice sampling, giving clear intelligibility for door communication. Control I\/O includes one contact input channel and five output channels covering both open collector and relay contact types, enabling integration with door strikes, access readers, and building management systems. The N-8640SB is the right choice when a project demands IP intercom capability that must conform to a custom panel layout rather than a manufacturer-defined form factor.\u003c\/p\u003e","brand":"TOA ELECTRONICS, INC","offers":[{"title":"Default Title","offer_id":52445261430968,"sku":"107698","price":1135.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/107698_TOA-N-8640SB-IP-Door-Station-Custom-Install-Sub-Station-Board-Kit_ALT01sqr.jpg?v=1789136673","url":"https:\/\/soundpro.com\/products\/toa-n-8640sb","provider":"SoundPro","version":"1.0","type":"link"}
