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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

For the purpose of promoting an understanding of the principles of the invention, reference will be made to the embodiment illustrated in the drawings with reference to FIGS. 1 and 2.

The present invention operates as an embeded-controled a microcontroller-controlled, Interrupt driven, state machine with 3 states.

STATE 1: Initialization.

STATE 2: Monitor.

STATE 3: Interrupt.

• • STATE 1: Initialization a software function programmed into the microcontroller (13) whereby, all interrupt flags input/output registers and constant values are defined.
  • STATE 2: Monitor, the microcontroller (13) is in “Sleep State” until an interrupt occurs, the fire sensor (22) and the Alarm IC (16) continuously monitor for a fire incidence, and the radio frequency receiver encoder (19) monitors for a matching system ID.
  • STATE 3: Interrupt; only two interrupts are possible interrupt-1 “LOCAL ALARM” caused by fire sensors (22) detection of a fire incidence which triggers the Alarm IC (16), in detect mode alarm IC concurrently outputs 5 volts (25) to the microcontroller (13) and begins Horn (28) output.

The microcontroller (13) outputs 5 volts (26) to the antenna switch (31) and enables, the multiple position encoder (34), this causes antenna switch (31) to change from its default assignment, the receiver encoder (19) to the decoder transmitter (40) and puts the multiple position encoders (34) output on the Data Bus (43) the microcontroller (13) then outputs 5 volts (46) reversing the default state of the decoder transmitter (40) off and the receiver encoder (19) on, with the antenna switch (31) set to transmit and the multiple position encoders (34) output, along with the 8-bit dip switch (49) output, applied to the decoder transmitter (40), the microcontroller (13) outputs 5 volts (41) to the transmit enable pin of the decoder transmitter (40) the system ID and INDEX of the label are transmitted (52) to all other system units the microcontroller (13) now enters a delay loop while the Horn (28) output continues along with the decoder transmitter (40) output.

After the delay ends the microcontroller (13) ends output (41) causing end of transmission (52), and then outputs 5 volts (55) which opens Q1 cutting off horns (28) output, and enables voice-chip (58), which begins playback at address given by the multiple position encoder (34) thur thru the 4 to 8-Bit Converter (61). The microcontroller (13) again enters a delay loop, while voice-chip (58) output continues, after delay ends the microcontroller (13) ends output (55), resets interrupt flag and returns to, “STATE 2” monitor.

Interrupt 2: is a “REMOTE ALARM” caused by receiver encoder (19) receiving (60) a matching system ID and output of 5 volts (17) from receiver encoder's (19) valid transmission pin to the microcontroller (13). The microcontroller (13) disables input (12) then outputs 5 volts (27) thur thru D1 to the alarm ICs (16) I/O causing alarm IC (16) to enter a detect state and begin horn (28) output, the microcontroller (13) now enters a delay loop, after delay ends, microcontroller ends output (27) alarm IC, (16) no longer in detect state ends Horn (28) output, the microcontroller (13) next outputs 5 volts (55) disconnecting the horn (28) from the alarm IC (16) by opening Q1 and enables the voice-chip (58), staring voice-playback At address supplied by output (70) of receiver encoder (19) thur thru 4-to-8 bit converter (61) microcontroller (13) again enters a delay loop, after delay ends microcontroller (13) ends output (55), resets interrupt flag and returns to “STATE 2” monitor.
