Abstract
Methods and apparatus for passive non-electrical dual stage fire suppression according to various aspects of the present invention include detecting a fire with a first active fire suppressant unit and changing the status of a second fire suppressant unit from “stand-by” to “active” when the first fire suppressant unit releases a fire suppressant agent. After the first fire suppressant unit has released its fire suppressant agent, the second fire suppressant unit may detect a continued and/or a new fire and release a second fire suppressant agent in response to the detection.
