Abstract An improved voice security system wherein the improvement resides in a non-electrical contact between a remote signalling apparatus and the standard microphone of a two-way radio so that voice transmissions may be accomplished in response to the sensing of a predetermined condition by sensors operatively connected to the remote signalling apparatus. The non-electrical contact is accomplished by the use of a voice and key unit which is electrically connected to the remote signalling apparatus and having a microphone holder mounted thereon whereby the standard microphone physically contacts the housing of the voice and key unit. A speaker is mounted within the voice and key unit housing, and the microphone is modified to include a reed switch which is actuated by a coil placed within the voice and key unit housing whereby, upon applying electrical energy to the coil, the reed switch will close to permit the microphone to transmit audio messages generated by the remote signalling apparatus.
An improved voice security system of the type including a remote signalling apparatus having at least one sensor for detecting a predetermined condition and generating a signal in response to a sensed condition, logic circuit means for receiving the signal, and voice synthesizer means for generating an audible message in response to the sensed condition wherein the improvement comprises means for transmitting the audible message to a remote location utilizing a two-way radio having a microphone, said means comprising a voice and key unit interposed between said voice synthesizer and said microphone of said two way radio.

An improved voice security system of the type including a remote signalling apparatus having at least one sensor for detecting a predetermined condition and generating a signal in response to a sensed condition, logic circuit means for receiving the signal, and voice synthesizer means for generating an audible message in response to the sensed condition wherein the improvement comprises means for transmitting the audible message to a remote location utilizing a two-way radio having a microphone, said means comprising a voice and key unit interposed between said voice synthesizer and said microphone of said two way radio.
Claim 3
Dependent Claim
95 words
An improved voice security system as in claim 1 wherein said voice and key unit comprises a housing, a speaker mounted inside said housing, said speaker being connected to the voice synthesizer means; a microphone bracket attached exteriorly of said housing and adjacent said speaker for receiving the microphone therein; and key means electrically connected to the remote signalling apparatus and to the microphone whereby the microphone is automatically actuated by the signalling apparatus to permit transmission of the audible message when the microphone is attached to said voice and key unit by said bracket.
Claim 4
Dependent Claim
