Abstract
A heat-sensitive assembly mountable as unit and responsive to predetermined ambient temperature conditions above normal room temperature for activating a device for protection against heat or fire, comprising thin metal plates soldered face to face with eutectic solder, with large surface area and small mass and minimum contact with the elements to which they are connected. Also an alarm assembly comprising a supporting housing, an acoustic device, a coupler assembly supported by said housing and connecting said acoustic device and said container, a thermally responsive assembly mounted on said coupler assembly. Means on said coupler assembly conducting gas from said container to said acoustic device. A valve is opened on activation of said thermally responsive assembly to cause actuation of said acoustic device. A visual signal is given by swinging down of a guard member if the container contents leak. A container can be snapped into its place in the coupler assembly. A resilient cantilever-type conduit connects the horn to the gas container and it is bent on activation of a heat-sensitive element to open a valve in the container and allow gas to pass through the conduit to the acoustic device.
