The Alarm Triggered Shut off Appliance System (ATSAS) relates to a safe control shut-off system for all utility appliances. It reduces the risks of fire and carbon monoxide poisoning before they occur by turning off utility appliances when the smoke detection / carbon monoxide alarms sound. As the alarms sound, the ATSAS automatically shuts off the appliance. This helps the occupants to take emergency action in the earliest stages of development of a fire / carbon monoxide breakout or prevents their occurrences when the occupant's direct action is impossible. The system has a tone decoder that is responsive only to the frequency range of the alarm's alert sound. The tone decoder prevents the system from being falsely activated by erroneous sounds. Once a smoke or gas leak occurs, the system detects the alert sound through its microphone, and energizes a relay or solenoid valve that turns off the supply line to the utility appliance.

In the first step, an alpha or beta amino carboxylic acid is allowed to react with an optimal (approximately stoichiometric) amount of an activated malonate or oxalate derivative with mild heating. Upon completion of the double coupling reaction, hydrolysis of the reaction mixture yields a diamide containing intermediate (a macro linker). In the second step, stoichiometric amounts of a diamine, preferably an orthophenylene diamine, are added to the macro linker intermediate in the presence of a coupling agent and heat. This second double coupling reaction, is allowed to proceed for a period of time sufficient to produce a macrocyclic tetraamido compound. The substituent groups on the alpha or beta amino carboxylic acid, the malonate, and the aryl diamine may all be selectively varied so that the resulting tetraamido macrocycle can be tailored to specific desired end uses. The macrocyclic tetraamide ligand may then be complexed with a metal, such as a transition metal, and preferably the middle and later transition metals, to form a robust chelate complex suitable for catalyzing oxidation reactions.
