Claim 6

Dependent Claim 61 words

second switching means being connected to sequentially interrupt the circuit between said tape recorder output and said telephone lines in accordance with recorded signals from said tape recorder output for producing dialing signals on said telephone lines and for temporarily interrupting said telephone lines at the end of a recorded voice message from said tape recorder to produce a hang-up condition,

Claim 7

Dependent Claim 61 words

second switching means being connected to sequentially interrupt the circuit between said tape recorder output and said telephone lines in accordance with recorded signals from said tape recorder output for producing dialing signals on said telephone lines and for temporarily interrupting said telephone lines at the end of a recorded voice message from said tape recorder to produce a hang-up condition,

Claim 8

Dependent Claim 96 words

A telephone-monitOred alarm system as set forth in claim 1 wherein load resistance means are placed across the telephone lines, to simulate an off the hook condition, and across the tape recorder output, to apply signals therefrom to the telephone lines, and the second switching means includes a relay having a coil connected to be energized by predetermined pulses of current through said load resistance means and a normally closed set of contacts positioned between at least one of the telephone lines and the load resistance for opening the telephone lines upon energization of the coil.
