Personal services telephone handset and system

A system for a user facility having secure and unsecure conditions which are monitored by detector devices deriving alarm signals in the presence of a said unsecure condition for transmission through a telephone system line to a security monitoring service having an alarm response capability, and said system further providing telephonic interactive communication through said telephone system line with a personal service facility having a telephonic access number, account code data associated with said user facility and an access protocol code, the system comprising:

• a console positioned within said user facility for receiving said alarm signals, the console having a console control circuit including a communication network connected with said telephone system line for select digital telephonic communication with said security monitoring service in response to one of said alarm signals and having a display and user control input panel;
• a telephonic handset having a housing assembly connectable for support by said console and including a hand-held component and a hook switch actuable to have on-hook and off-hook states;
• a microphone and speaker mounted with said hand-held component of said housing assembly for interactive communication with a user;
• a plurality of discrete service request switches mounted upon said housing assembly and each associated with a said personal service facility and manually actuable to effect derivation of a corresponding service code in an access mode and to effect derivation of a number signal in an interactive mode;
• a speech and signaling network coupled with said console control circuit to said telephone system line and having a DTMF input and a mute function input;
• a dual tone multi-frequency (DTMF) decoder network coupled with said console control circuit to said telephone system line and having a digital output;
• memory means for receiving and retaining account codes and personal service facility telephone numbers;
• and
• control means coupled with said memory means, said service request switches, said speech and signaling network, said DTMF input and mute function input and said DTMF decoder network, responsive to a program mode input for entering a programming mode, responsive in said programming mode to an applied select service code, an applied predetermined telephonic access number, and an applied account code corresponding with said account code data for effecting their transfer to said memory means, responsive in the presence of said off-hook state to a first received service request switch service code for entering said access mode and, during said access mode, accessing said memory means for corresponding said account code and corresponding said predetermined telephonic access number for effecting the calling and telephonic communication with a select and service facility at said predetermined telephonic access number and subsequently responsive to the receipt of said access protocol code from said select service facility as a said digital output from said DTMF decoder network for effecting the transmission of said account code;
• said console control circuit being responsive to one of said alarm signals to block access of said telephonic handset to said telephone system line during said select digital telephonic communication.
