An actuator assembly for use in fire suppression systems for use in vehicle and industrial fire protection systems. The actuator assembly engages a cartridge of pressurized gas and releases the gas contained therein with a puncturing assembly. The actuator assembly includes a receptacle that controls the manner in which the actuator assembly and cartridge engage one another. The actuator assembly is configured for electrical and pneumatic actuation for rupturing the seal of the cartridge of pressurized gas. The actuator assembly has a housing that includes at least one inlet port that is coupled to a pressurized gas source, which is formed between a first chamber for electrical components sealed from the operative environment of the actuator assembly and a second chambers for the puncturing assembly. The actuator assembly allows for serial interconnection of multiple actuator assemblies for operation by a single source of pressurized gas.

A method for extinguishing objects or appliances, in which, once a fire signal has been detected at point in time t1, a first device (17) providing an extinguishing agent is triggered, for discharging a liquid synthetic extinguishing agent (14), via a separating device (8), a common conveying pipe (9) and at least one nozzle (10), and, once a second fire signal has been detected at point in time t2, a second device (18) providing an extinguishing agent is triggered for discharging water (3) or a water-based extinguishing agent via the separating device (8), the common conveying pipe (9) and the at least one nozzle (10) for extinguishing. A system is also provided for extinguishing objects or appliances.

A fire detection and/or extinguishing control station for actuating two extinguishing agent supply devices using a control unit. After actuating a first extinguishing agent supply device (17) upon detection of a first fire signal at time (t.sub.1), the control station is additionally equipped to actuate a second extinguishing agent supply device (18) upon detection of a second fire signal at time (t.sub.2) if the control station has checked whether the time (t.sub.2) fulfills the inequality (t.sub.1+t.sub.c)<t.sub.2<(t.sub.1+t.sub.b), where (t.sub.c) represents a discharge time of the complete or partial discharge of at least one extinguishing agent container (1) of the first extinguishing agent supply device (17), (t.sub.k) represents a check time connected to the discharge time (t.sub.c), and (t.sub.b) represents a monitoring time period, and the monitoring time period (t.sub.b) is the sum of the discharge time (t.sub.c) and the check time (t.sub.k) beginning at time (t.sub.1).

An apparatus, system and method have a sensor positioned above a rear axle attached to a brake of a trailer. The sensor detects whether the temperature of the brake exceeds a threshold temperature. A light is mounted on the trailer and activates in response to the temperature of the brake exceeding the threshold temperature. A handle is pulled to distribute a fluid on the rear axle of the trailer. A conduit extends across the underside of the trailer wherein the conduit carries the fluid. A nozzle sprays the fluid over the rear axle.

The present invention generally provides systems and methods for autonomous space characterization, data analysis, anomaly detection, hazard probability assessment, and profile deviance assessment and incident response action, and firefighting employing robotically controlled firefighting equipment, autonomous selection and release of firefighting agent, and the autonomous prediction, detection, classification, and location of existing and impending threats and fire events.

An aircraft comprises a fuselage having a compartment, and a fire suppression system for delivering fire suppressant to the compartment. The system includes at least one suppressant concentration sensor located in the compartment, a valve for regulating flow of the fire suppressant to the compartment, and a controller, responsive to the sensor, for controlling the valve to maintain fire suppressant concentration within the compartment at a target concentration.

A passive fire response system is configured to suppress a metallic fire. The system includes a reservoir containing an ionic liquid, at least one outlet in communication with the reservoir, a valve arranged between the reservoir and the outlet, a sensor configured to sense at least one of a hydrogen concentration and a temperature and/or heat, and a controller configured to open the valve and release the ionic liquid if an output from the sensor indicates that the at least one of the hydrogen concentration and the temperature equals or exceeds at least one of a threshold hydrogen concentration and a threshold temperature.
