A control mechanism includes an actuator having first and second positions, a resilient member arranged to bias the actuator toward the second position, and an input cable. The input cable is arranged along a serpentine path and is connected to the actuator, the input cable arranged to retain the actuator in the first position using tension applied by a plurality of detector cables along the serpentine path of the input cable. Fire detector connector modules, fire suppression systems, and methods of integrating detector cables into control mechanisms are also described.

A safety cabinet includes an enclosure and at least one door to selectively seal the enclosure. The safety cabinet can be used to store, for example, flammable liquids, flammable waste, corrosives, pesticides, or combustible waste. The safety cabinet incorporates a thermally-actuated damper that includes a body, a valve plate, and a pivot assembly. The valve plate is disposed within the passage of the body such that the valve plate is movable between an open position and a closed position. The pivot assembly includes a biasing system adapted to bias the valve plate to the closed position and a fusible link interconnected between the body and the biasing system to constrain the valve plate from moving from the open position to the closed position. The fusible link is configured to melt at a predetermined temperature to thereby allow the biasing system to move the valve plate to the closed position.

A fire rated pet door closure and assembly adapted to be mounted on the attached garage side of a fire wall or fire door in part defining an enclosure such as a house or living area over a pet door access passageway opening from the inside of the fire wall or fire door to the outside thereof which pet door is normally selectively open, for pet egress. The onset of a fire/heat emitting emergency mechanical fusible apparatus is provided such that the fire rated pet door closure supporting release link apparatus with a predetermined release temperature activates a latch support for the fire rated pet door closure panel which automatically closes via gravity sealing the pet door access passageway with intumescent smoke and draft seals.

A hot melt safety door holder device includes: a first fixing part on one side of swing end of swing door sheet; a holder with a transverse through hole and the outer hole end faces towards the first fixing part; a second fixing part in the transverse through hole, the first radial end faces towards the outer hole end of transverse through hole, the second radial end faces towards the inner hole end; a conically cylindrical space, formed between the periphery of the second fixing part and the transverse through hole, and the inside and outside diameters of the end between the transverse through hole and the second fixing part corresponding to the space tapering end of conically cylindrical space are fitted with each other. The shape of the low-melting metal material filled in the conically cylindrical space matches the shape of conically cylindrical space, resulting in equal wall thickness.

A safety cabinet includes an enclosure and at least one door to selectively seal the enclosure. The safety cabinet can be used to store, for example, flammable liquids, flammable waste, corrosives, pesticides, or combustible waste. The safety cabinet incorporates a thermally-actuated damper that includes a body, a valve plate, and a pivot assembly. The valve plate is disposed within the passage of the body such that the valve plate is movable between an open position and a closed position. The pivot assembly includes a biasing system adapted to bias the valve plate to the closed position and a fusible link interconnected between the body and the biasing system to constrain the valve plate from moving from the open position to the closed position. The fusible link is configured to melt at a predetermined temperature to thereby allow the biasing system to move the valve plate to the closed position.

There is provided a fire collar comprising a casing defining a service conduit passage therethrough, the casing having an activation side and an installation side, wherein the casing defines an activation side located activation chamber. The fire collar has an opposing pair of shutters located within the activation chamber defining operative leading edges. In use, the shutters are configurable in a non-activated configuration wherein the leading edges are spaced apart so as to make allowance for the service conduit therebetween and when the fire collar is exposed to heat on the activation side in use, the shutters transition to an activated configuration wherein the respective leading edges of the shutters close in the passage.

The present invention relates to an integrated basement ventilation apparatus, and more particularly, to an integrated basement ventilation apparatus which can improve a basement ventilation apparatus and thereby perform an adiabatic cooling using latent heat when air is supplied, and in a case of outbreak of fire, forcibly close a damper closed or opened by itself as air is exhausted, and allow general automatic control depending on a local air condition in a basement structure and which can control an increase in temperature in the basement structure at a low cost and enhance a fire safety, and in particular, can suppress the fire early and significantly enhance the quality of air in the basement structure, thereby significantly enhancing condition and maintenance of whole facilities.

A hydrogen fusible link may include a first link member having a thermally conductive material, and reaction region and a bonding region. A bonding material may be in a solid state at an operating temperature and may have a melting temperature that is greater than the operating temperature. A catalyst material may coat the reaction region and may facilitate an exothermic chemical reaction when exposed to gaseous hydrogen to produce heat, wherein heat produced by the catalyst material is conducted to the bonding region via the body to heat up the bonding material. When the catalyst material is exposed to a concentration of gaseous hydrogen that is at or above an activation concentration the reaction region produces sufficient heat to raise at least some of the bonding material above the melting temperature thereby failing at least some of the bonding material.

A generator enclosure for an engine-generator includes multiple walls defining at least one air path. In one example, a first wall includes an exhaust path for the engine-generator, and a second wall includes an intake path for the engine-generator. The generator enclosure may include at least one air flow frame associated with the exhaust path or the intake path and at least one movable wall supported by the at least one air flow frame, At least one thermal fuse may be coupled to the at least one movable wall and configured to release the at least one movable wall to block the exhaust path or the intake path.
