Abstract:
1. Testing apparatus for testing a gas or combustion product detector comprising: a container containing a material dispensable as a spray, aerosol or particulate through an outlet aperture, wherein the material dispensable as a spray, aerosol or particulate is representative of a gas and/or combustion product for testing a gas or combustion product detector, and wherein the container includes a valve actuator or switch arranged to be actuated by a user in order to enable release of the spray, aerosol or particulate through said outlet aperture, said outlet aperture pointing axially to the container axis; and a spacer member, wherein the spacer member is movable between a first position which is convenient for carrying or storage and a second position which determines a minimum distance between the outlet aperture and a target surface area or object of the product detector for the spray, aerosol or particulate, said spacer member having a ring attached to the container at one end, said ring having a section axially extending from said ring wherein said axially extending section is narrower in diameter than said container, said spacer member comprising one or more telescopically extending sections, wherein said one or more sections are narrower than an outer diameter of said container, and wherein said one or more sections inhibit access to actuation of the valve actuator or switch when in said first position, and wherein said one section attached to the ring is provided with a side wall having a side wall aperture to permit access of a user's finger to the valve actuator or switch of the container and operation of the valve actuator or switch when the spacer member is in said second position such that a distal end of one or more sections opposite said end attached to the container is proximal said target area, wherein there are one or more intermediate sections between a furthest section from the container and the section attached to the ring and wherein any or all of the intermediate sections each has a side wall, and at least one said side wall is provided with a plurality of apertures, and one or more intermediate sections and the furthest section of the spacer member are arranged to move solely in an axial direction to the container axis, between the first position and second position, and wherein the material dispensable as a spray, aerosol or particulate that is representative of a gas and/or combustion product is adapted to be released from the furthest section of the container to the target area which is different than the side wall aperture which permits access of a user's finger to the valve actuator or switch of the container when the spacer member is in the second position.
