System and method for suppressing the spread of fire and various contaminants
First Claim
1. A system for suppressing the spread of contaminants, the system comprising:
- an HVAC interface in communication with-a residential HVAC system;
a receiver operable to receive a signal indicating the presence of a contaminant from an environmental condition detector; and
a processor in communication with said receiver and said residential HVAC system and operable to;
receive said signal from said receiver, in response, send a signal to said HVAC interface to cause said residential HVAC system to be shut down, and minimizing collision of data packets during transmission of data signals by;
(a) determining the presence of an existing transmission;
(b) if no transmission is present, transmitting a message;
(c) generating a pseudo random number;
(d) calculating a delay comprising the sum of a fixed time interval and the pseudo random number;
(e) pausing for an interval equal to said delay; and
(f) repeating steps (a) through (e).

Abstract
Systems and methods for suppressing the spread of fire, fire-related toxins, and other biological and chemical hazards are disclosed. One described system includes an HVAC interface in communication with-a residential HVAC system, a receiver operable to receive a signal indicating the presence of a contaminant from an environmental condition detector; and a processor in communication with the receiver and the residential HVAC system. The processor is operable to: receive the signal from the receiver, in response, send a signal to the HVAC interface to cause the residential HVAC system to be shut down, and minimizing collision of data packets during transmission of data signals.
