A method of proactively defending combustible property against fire ignition and flame spread in the presence of wild fire. The method involves establishing wireless communication between a GPS-tracking anti-fire (AF) chemical liquid spraying system, and a wireless communication network supporting a network database. The GPS-tracking anti-fire chemical liquid spraying system is used to spray an environmentally-clean anti-fire chemical liquid over the exterior surfaces of a GPS-specified combustible parcel of property, and generating a GPS-coordinate and time/date stamped data records pertaining to the application of the environmentally-clean anti-fire chemical liquid spray over the exterior surfaces of the GPS-specified combustible parcel of property. The GPS-coordinate and time/date stamped data records are transmitted over the wireless communication network for storage in the network database. A computing system is used to access the GPS-coordinate and time/date stamped data records from the network database, so as to verify that the GPS-specified parcel of property has been fire-protected on particular date by virtue of the GPS-specified property being sprayed with the environmentally-clean anti-fire chemical liquid so as to proactively inhibit fire ignition and flame spread in the presence of wild fire.

A thermal trigger assembly for remote mechanical actuation of another fire protection system component includes an activation component having a base and a movable member. A bias member biases the movable member from a preactivation to an activated position with respect to the base. A thermally responsive element retains the movable member in the preactivation position until a predetermined thermodynamic condition is reached, when the thermally responsive element loses structural integrity. A flexible connector includes a flexible hollow outer cable housing with one end configured to be stationarily (preferably fixedly) connected with the base. A flexible cable is inside the outer cable housing for sliding movement therein and has one end configured to be stationarily (preferably fixedly) connected with the movable member. The flexible cable is moved with respect to the outer cable housing by movement of the movable member upon loss of structural integrity by the thermally responsive element.

A wind turbine comprising a tower, a pod, at least one smoke detector in the region of the tower and/or in the region of the pod, at least one fan arranged in the tower and/or in the pod, and a control unit which detects a fire situation or smoke development in the wind turbine by means of the smoke detectors and activates the fans disposed in the tower and/or in the pod in order to suck away the smoke produced.

A fusible mechanical linkage includes a tensioner having an aperture and a spool with guides arranged on an end of the spool opposite the aperture. The guides define a cable seat between one another. A fusible alloy is arranged between the spool and the tensioner, the fusible alloy fixing the spool to the tensioner below a predetermined temperature, the fusible alloy allowing tension carried by an actuation cable received in the cable seat to rotate the spool relative to the tensioner above the predetermined temperature. Fire suppression systems and methods adjusting actuation cables in fire suppression systems are described.

A method of operating a suppression system includes opening a discharge valve associated with a pressurized vessel containing suppression agent in response to detection of a hazardous condition within an area being monitored, releasing suppression agent into the area being monitored via a discharge nozzle, and detecting that the hazardous condition is no longer present in the area being monitored. The discharge valve is closed by the actuator in response to detecting that the hazardous condition is no longer present in the area being monitored.

A nozzle box unit forming a component of an anechoic chamber fire suppression system is provided. The nozzle box unit includes a pusher assembly that is configured to dislodge a piece of acoustic material positioned in front of the nozzle box so as to permit discharge of a fire suppressing material from a nozzle mounted inside the nozzle box unit into the anechoic chamber.
