Abstract

An indexed database alarm and monitor, for assigning each unit of a multiple unit system a labeled index of pre-selected designations, and or descriptions of use by voice-playback and reporting, by voice-playback of first detecting units designation and or description of use by each unit in the system. Being comprised of the following components, a fire sensor, an alarm IC with piezo horn and detection I/O, a multiple position encoder, a 8-bit dip switch, a radio frequency decoder transmitter and receiver encoder with antenna switch and antenna, a voice-playback device with speaker and a microcontroller all housed within one unit. A complete system being comprised of a plurality of said units, equal to the number of positions on the multiple position encoder, each units multiple position encoders position being different and generating a different index.The indexed database alarm and monitor system of the present invention is designed to provide whole house monitoring and whole house reporting of a fire incidence. In the event of a fire incidence a first detecting unit outputs a fixed alarm followed by voice-playback of a user assigned, pre-recorded voice-segment that designates the units installation site and describes its use as a smoke detector, while also transmitting a radio signal that contains a database index to other indexed database alarm and monitor units to activate their fixed alarms and index their voice-playback devices voice-segment database to output the first detecting unit assigned installation site related voice-segment from their installation sites, user assignment of installation site and database index, are provided by a multiple position encoder, each units multiple position encoders control knob position, assigning a different installation site and generating a different database index.

Claims

1. An indexed database alarm and monitor system, for assigning each unit of a multiple unit system, from a position labeled index of pre-selected designations and or descriptions of use by a voice-playback and reporting, by an audible fixed pattern alarm followed by said voice-playback of a first detecting units assigned designation and or description of use by said each unit in the system;

each said unit consisting of the following components, a firesmoke sensor, an alarm IC with piezo horn output and detection I/O, a multiple position encoder, a 8-bit dip switch, a radio frequency decoder transmitter and a receiver encoder, an antenna switch and an antenna, a voice-playback device with speaker, and a microcontroller all housed within one unit;

a complete system being comprised of a plurality of said units, equal to the number of positions, on the multiple position encoder;

wherein said multiple position encoder has said index of labeled positions and outputs a different 4-bit binary coded decimal at each said labeled position to be used as a database index,

wherein said voice-playback device contains indexed pre-recorded voice segments with 8-bit starting addresses, as a database;

wherein said labeled positions relate to the indexed pre-recorded voice segments, and the multiple position encoders, output at each labeled position is used as the index into the voice segment database, being mapped one-to-one into thesaid 8-bit starting address of a voice segment;

wherein said radio frequency decoder transmitter of said first detecting unit decodes and transmits a 12-bit signal, consisting of an 8-bit system ID from the 8-bit dip switch, and the 4-bit database index from theits said multiple position encoder,

thewherein said radio frequency receiver encoder validatesencoders of all other units validate the transmitted 8-bit system ID and outputsapply the transmitted 4-bit database index to their said voice-playback devices;

said antenna switch and said antenna default to the radio frequency receiver encoder unless firesmoke sensor detects smoke, if smoke detected said antenna switch is enabled and said antenna is applied to the decoder transmitter;

said microcontroller is used as a state machine and is interrupt driven with 3-states initialization, monitor and interrupt, only two interrupts are allowed interrupt 1-local, said fire smoke sensor detects smoke, and interrupt 2-remote, said receiver encoder validates transmission of matching said 8-bit system ID.
