A gas sensor having first and second electrodes, an ion conducting solid electrolyte membrane positioned therebetween, first and second electrically conductive gas diffusion layers, first and second electrode contact members for electrically coupling said first and second electrodes to art external circuit, a water reservoir, a gas entry passageway and a water permeation barrier for controlling the transport of water vapor to the ion conducting solid electrolyte membrane. The water permeation barrier is a thin walled member which allows water vapor to diffuse therethrough and evaporate from an exit surface, the thickness of the water permeation barrier controlling the internal relative humidity of the sensor. A method for adjusting the present sensor in-situ due to changes in the current humidity conditions of the sensor so as to keep the gas sensitivity loss within a predetennined range is also disclosed.

Abrégé

An aerosol fire extinguisher for dispensing a liquid wet chemical fire extinguishing agent, and a composition for the liquid wet chemical fire extinguishing agent, where the liquid wet chemical fire extinguishing agent is rated for class A, B, C and K fires. The fire extinguisher includes a container and a valve assembly affixed to the container. A bag is positioned within the container, where the bag includes an output tube connected in fluid communication to the valve assembly. A actuator is connected in fluid communication to the valve assembly opposite the output tube, where the actuator has an elongated output orifice. A liquid wet chemical fire extinguishing agent is disposed within the bag and a propellant is disposed within the container, wherein the bag isolates the liquid wet chemical fire extinguishing agent from the propellant. The configuration of the elongated output orifice expels the liquid wet chemical fire extinguishing agent in a substantially planar pattern onto the fire.

Abrégé

A wireless detector and alarm system, such as for example a smoke detector and/or carbon monoxide (CO) detector, operable to be linked and unlinked with one or more like detectors thereby forming a network of detectors. A detector sensing the presence of an environmental condition, which requires the sounding of an alert is operable to transmit a signal to other remotely linked detectors, thereby triggering the remotely linked detectors to sound an appropriate alarm. The detector at the location of the environmental condition causing the alar and the remotely linked detector are capable to operate in teach and learn modes such that the address or 'house codes' of the detectors can be synchronized.
