Abstract

A security system for monitoring and detecting security breaches in a home comprises a central monitor and a plurality of remote sensors for one or more of fire, smoke, intrusion, appliance operation and the like. Each of the sensors has a transmitter for transmitting an electronic message when the sensor goes into an alarm condition. The central monitor has a receiver to receive the electronic messages. An electronic microprocessor system decodes the received electronic message and takes the necessary course of action in accordance with a programmable scheme retained in electronic memory of the microprocessor system. The central monitor has a speech synthesizer responding to inputs from the microprocessor system. A keyboard is provided on the central monitor for allowing a user to interact with the security system. The microprocessor system is programmable via the keyboard to permit the user to customize the programmable scheme to render it unique to the user. The microprocessor system actuates the speech synthesizer to synthesize predetermined messages in response to input from the keyboard and in accordance with the programmable scheme based on received electronic message from the transmitters. The microprocessor system is capable of checking data as it is entered by the keyboard against what is required by the programmable scheme. This checking system permits the security system to announce an error message should the entered data be incorrect.

Claims

1. A security system comprising a central monitor and a plurality of remote sensors for one or more of fire, smoke, intrusion, appliance operation and the like, each of said sensors having a transmitter for transmitting an electronic message when said sensor detects an alarm condition, said central monitor having a receiver to receive such electronic message, and an electronic microprocessor control system to decode the received electronic message an taking a necessary course of action in accordance with a programmable scheme retained in an electronic memory of said microprocessor system, said central monitor having a speech synthesizer responding to inputs from said microprocessor system, a keyboard being provided on said central monitor for allowing a user to interact with said security system, said microprocessor system being programmable via said keyboard thereby permitting a user to customize said programmable scheme by interaction with said security system through said keyboard to render thereby the scheme unique to such user, said microprocessor system actuating said speech synthesizer to synthesize predetermined messages in response to input from said keyboard and in accordance with said programmable scheme, said microprocessor system having means for checking data as it is entered by said keyboard against what is required by said programmable scheme, means for initiating said microprocessor system to actuate said speech synthesizer to synthesize a message relating to information input by said keyboard, said initiating means causing an error message to be synthesized when information entered via said keyboard is in error when said checking means verifies such information against what is required by said programmable scheme, and an internal speaker and an external speaker, said microprocessor system actuating said internal speaker to announce said error message, said microprocesor system actuating said external speaker to announce an alarm message produced by said speech synthesizer when said sensor detects an alarm condition, means for driving said external speaker to sound a siren alarm, said microprocessor system selectively actuating said siren driving means to sound said siren alarm on actuating said external speaker to announce an alarm message generated by said speech synthesizer.

2. A security system of claim 1, wherein said speech synthesizer comprises a second microprocessor separate from said microprocessor control system, said microprocessor control system intercommunicating with said second microprocessor.

3. A security system of claim 1, wherein means senses signal strength level of said transmitted electronic message, means for connecting signal strength level sensed by said sensing means into digital code representative of high, medium, low or weak strengths, said speech synthesizer being actuated by said microprocessor system to announce a message of high, medium, low or move corresponding to the sensed signal strength level.

4. A security system of claim 2 wherein said second microprocessor includes means for dialing a predetermined sequence of telephone numbers, programmable electronic memory for storing telephone numbers and means for addressing said electronic memory to select a telephone number to be dialed by said dialing means, a microphone for picking up ambient noise, means for selectively connecting said microphone to a telephone network and amplifying any picked up ambient sound for transmission over a telephone network, in the event of a predetermined type of alarm condition said microprocessor control system actuates said dialing means to dial a selected telephone number, said microprocessor control system actuating said speech synthesizer to generate a message to be transmitted over a telephone network, said microprocessor control system actuating said means for selectively connecting said microphone to a telephone network after a message has been transmitted to permit thereby a person connected to such telephone network to listen to ambient sound through said microphone in an area being monitored by said security system.

5. A security system of claim 4, wherein said microprocessor control system having means for directing data entered by said keyboard to said second microprocessor for storage in said programmable electronic memory, said microprocessor control system actuating said speech synthesizer to generate a message requesting specific information of a user, said directing means directing a user'"'"'s data input via said keyboard to said programmable memory means, said speech synthesizer having means for connecting a user'"'"'s at a input stored on said programmable memory means into an analog announcement, said microprocessor control system actuating said speech synthesizer to announce through at least one of said internal and external speakers said analog announcement to enable a user to verify accuracy of data entered by said keyboard, said microprocessor control system having means for permitting a user to reenter data in the event verification of data by a user requires a change in data previously entered.

6. A security system of claim 1, wherein said microprocessor control system includes means for actuating either said external speaker remote of said central monitor or internal speaker of said central monitor as predetermined by type of message to be announced, said microprocessor control system directing said actuating means for said speakers to actuate only said external speaker in the event of announcing an intrusion alarm condition to avoid thereby an intruder locating said central monitor.
