{"product_id":"viking-k-1900-3-controller","title":"Viking K-1900-3 Controller","description":"\u003cp\u003eThe Viking K-1900-3 Auto Dialer transforms any touch-tone phone into a powerful multi-number auto dialer, capable of storing up to 250 phone numbers in non-volatile memory. Pair it with Viking’s K-1700-3 or K-1900-8 phones for vandal-resistant, hands-free, or handset communication. When a call is answered by a tenant, the built-in contact closure can activate an electric gate or door strike, ensuring secure access control. Additionally, the K-1900-3 supports 250 programmable keyless entry codes, including a master code and up to five maintenance codes. For added security, it offers user dialing restrictions to prevent unauthorized calls and toll fraud, and it can be programmed locally or remotely using any standard touch-tone phone.\u003c\/p\u003e\n\u003ch3\u003e\u003cu\u003eCore Features:\u003c\/u\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with Viking’s vandal resistant K-1700-3,\u003cbr\u003e\nK-1900-8 or any touch tone phone\u003c\/li\u003e\n\u003cli\u003eNon-volatile memory (no batteries required)\u003c\/li\u003e\n\u003cli\u003eRemotely or locally programmable\u003c\/li\u003e\n\u003cli\u003eStores 250 tenant touch tone phone numbers and keyless entry codes\u003c\/li\u003e\n\u003cli\u003eProgrammable tenant’s relay activation code\u003c\/li\u003e\n\u003cli\u003eProgrammable master keyless entry code and five maintenance codes\u003c\/li\u003e\n\u003cli\u003eProgrammable call timer\u003c\/li\u003e\n\u003cli\u003eMulti-number dialer mode (for Kiosks, etc.)\u003c\/li\u003e\n\u003cli\u003eRing-thru mode for calling the entry phone\u003c\/li\u003e\n\u003cli\u003eNormally open and normally closed (DPDT)\u003cbr\u003e\nrelay contacts for controlling door strikes, magnetic locks, gates, etc.\u003c\/li\u003e\n\u003cli\u003eAuxiliary relay input to trigger a timed relay activation for postal locks, etc.\u003c\/li\u003e\n\u003cli\u003eTouch tone and pulse dialing toll restriction\u003c\/li\u003e\n\u003cli\u003eProgrammable allow\/restrict for 911 and 311 outside calls\u003c\/li\u003e\n\u003cli\u003eLog bus data output for logging entry events\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Viking","offers":[{"title":"Default Title","offer_id":46237934420139,"sku":"VIK-K-1900-3","price":237.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/8939\/3579\/files\/K-1900-3.jpg?v=1771970700","url":"https:\/\/primebusinessphone.com\/products\/viking-k-1900-3-controller","provider":"PrimeBusiness Phone","version":"1.0","type":"link"}
