with EXP250-KIT

Door Entry Dialer

June 22, 1998

Provide Door Entry for up to

250 Apartments or Offices

The K-1900-3 provides reliable and economical door entry control for apartments or business complexes.

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 E 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 electronic gates or door strikes. A keyless entry code can also be programmed, allowing tenants to let themselves in.

The K-1900-3 can be programmed locally or remotely using a standard Touch Tone phone.

This Technical Practice is only for use with the K-1900-3 with the optional EXP250-KIT. All other
