250 Number Apartment Dialer. The K-1900-3 converts any touch tone phone into a multi-number auto dialer that will store up to 250 telephone numbers in non-volatile E2 memory. Use with Viking s K-1700-3 or K-1900-8 phones to provide vandal resistant handsfree or handset communication. When a call initiated by the K-1900-3 is answered by an apartment or business tenant, a built-in contact closure may be activated to control an electric gate or door strike. Up to 250 keyless entry codes may also be programmed, providing tenants with keyless entry. In addition, a master keyless entry code and up to five maintenance codes can be programmed. Calling activity and keyless entry use can be monitored using the log bus data output. The K-1900-3 can be programmed locally or remotely using a standard Touch Tone phone. The K-1900-3 has built-in user dialing restriction to help prevent unauthorized calls and toll fraud.
