Building environment monitor and control system
First Claim
1. An appliance monitor and control system, comprising:
- one or more system sensors each of which is arranged to detect a hazardous condition and to produce a corresponding alarm signal in an environment including a water service supply line, a fuel service supply line, and an electric service supply line, and one or more appliances including a combustion fueled water heater or boiler having a water feed inlet for communication with the water service supply line and a fuel inlet for communication with the fuel service supply line, wherein the fuel inlet is operative to close in the absence of an associated electrical connection;
a number of control devices wherein each control device is constructed and arranged operatively to disconnect a corresponding service supply line from one or more of the appliances to which the supply line is connected, in response to a corresponding drive signal;
a processor/driver having one or more inputs coupled to the system sensors and one or more outputs coupled to the control devices, wherein the processor/driver is configured so that a given control device is driven in response to an alarm signal originating from a corresponding one or more of the system sensors;
one of the system sensors is a first water sensor constructed and arranged for location in the vicinity of the water heater or boiler; and
the control devices include at least, (i) a switch mechanism constructed and arranged for connection to a part of the fueled water heater or boiler, wherein the switch mechanism is configured to remove the electrical connection associated with the fuel inlet of the water heater or boiler in response to a water alarm drive signal that is produced by the processor/driver in response to the alarm signal from the first water sensor, thus closing the fuel inlet to the water heater or boiler, and (ii) a first water control valve constructed and arranged for connection to the water feed inlet of the water heater or boiler, wherein the first water control valve is configured to shut off a supply of water from the water service supply line to the water heater or boiler in response to the water alarm drive signal from the processor/driver.

Abstract
A monitor and control system that responds to alarm signals representing different hazardous conditions in an environment having a number of utility service supply lines, such as a home residence. One or more sensors coupled to the processor are each associated with one or more of the service supply lines. Each sensor produces an alarm signal in response to a hazardous condition attributable to an associated supply line. Each associated supply line is provided with a control device that is coupled to an output of the processor, and the processor is configured to produce one or more output signals in response to an alarm signal at a given input. Each control device is arranged to disable its associated supply line with respect to a sensed hazardous condition in response to a corresponding output signal from the processor.

12. An appliance monitor and control system, comprising:
-
one or more system sensors each of which is arranged to detect a hazardous condition and to produce a corresponding alarm signal in an environment including a water service supply, a fuel service supply line and an electric service supply line, and one or more appliances including a water heater or boiler that is either combustion fueled or electrically powered;
a number of control devices wherein each control device is constructed and arranged operatively to disconnect a corresponding service supply line from one or more of the appliances to which the supply line is connected, in response to a corresponding drive signal;
a processor/driver having one or more inputs coupled to the system sensors and one or more outputs coupled to the control devices, wherein the processor/driver is configured so that a given control device is driven in response to an alarm signal originating from a corresponding one or more of the system sensors;
the processor/driver is configured to operate in a selected one of a first mode wherein the water heater or boiler is designated as a combustion fueled water heater, or a second mode wherein the water heater is designated as an electrically powered water heater;
one of the control devices is a switch mechanism constructed and arranged for connection to a part of the fueled water heater or boiler, wherein the switch mechanism is configured to remove an electrical connection associated with a fuel inlet of the fueled water heater or boiler in response to a heating supply switch drive signal that s produced by the processor/driver in response to a water alarm signal from a first water sensor in the vicinity of the fueled water heater or boiler, when the processor/driver is in the first mode; and
the processor/driver is configured to inhibit said heating supply switch drive signal when the processor/driver is in the second mode. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
