Abstract
A fire protection system and method for an enclosure includes an inert agent supply source configured to discharge an inert agent following a discharge of a primary agent in the enclosure, a gas detector configured to determine a gas concentration level in the enclosure, and a controller connected with the inert agent supply source and the gas detector and configured to regulate the discharge of the inert agent into the enclosure based at least partially upon the gas concentration level.
Claims15
A fire protection system for an enclosure, comprising:
- an inert agent supply source configured to discharge an inert agent following a discharge of a primary agent in the enclosure;
- a gas detector configured to determine a gas concentration level in the enclosure;
- and
- a controller connected with the inert agent supply source and the gas detector and configured to regulate the discharge of the inert agent into the enclosure based at least partially upon the gas concentration level;
- wherein the primary agent comprises a halogenated fire suppression agent;
- wherein the gas detector is an oxygen level detector configured to determine an oxygen concentration level in the enclosure;
- wherein the controller is configured to initiate discharge of the inert agent when the oxygen concentration level exceeds a predetermined oxygen concentration level threshold.
A method of fire protection for an enclosure, the method comprising:
- discharging a primary agent in the enclosure;
- determining a gas concentration level in the enclosure;
- and
- discharging an inert agent in the enclosure upon a determination that the gas concentration level is greater than a predetermined gas concentration threshold;
- wherein the primary agent comprises a halogenated fire suppression agent;
- and
- wherein the inert agent includes one or more of nitrogen, argon and carbon dioxide;
- wherein determining the gas concentration level includes determining an oxygen concentration level in the enclosure;
- wherein discharging the inert agent in the enclosure occurs upon a determination that the oxygen concentration level is greater than a predetermined oxygen concentration threshold.
