Horizontal window fire protection sprinklers, systems and methods are provided. The sprinklers include a frame and a fluid deflection member including a window confronting surface having a planar portion and a concave portion. The sprinkler defines a maximum operating pressure of at least 100 psi. per sprinkler for adjacent sprinklers without cold soldering.

Provided herein are a fire suppression device or control device for putting out a fire using a high pressure water and air-line to propel and diffuse the water as a mist towards the flames. The device has a cylindrical pipe with a diffuser nozzle on one end, a Y-connector on the other end, shutoff valves that regulate the flow of water and air to the nozzle, and at least one hook disposed on the device to brace or anchor the device to a wall. Also provided is a barrier-penetrating fire suppression system with a penetrator assembly mounted on a vehicle platform boom. The penetrator assembly is perpendicularly aligned with a barrier whereupon a striker shaft propels a piercing nozzle through a barrier before water is sprayed from the nozzle.

An automatic smoke/carbon monoxide evacuation system for a building having at least one existing ventilation fan and at least one ventilation passageway to outside the building is provided. The system includes a microprocessor and a smoke/carbon monoxide sensor coupled to the microprocessor and configured to detect presence of smoke/carbon monoxide and send a trigger signal to the microprocessor in response to detecting smoke/carbon monoxide. A power switch is coupled to the existing ventilation fan and is configured to automatically connect the existing ventilation fan to a power source in response to the trigger signal, so that the ventilation fan rotates at a high speed to ventilate the detected smoke/carbon monoxide via the existing ventilation passageway. An alarm device is further communicably coupled to the microprocessor and is configured to issue an alarm in response to the trigger signal.

A fire exposure protection sprinkler assembly provides fire exposure protection for one or more windows and includes a fire exposure protection sprinkler, a sealing assembly configured to unseal in response to a fire such that fire exposure protection fluid may flow from the fire exposure protection sprinkler, and a housing having a pair of legs, with each of the legs having an aperture. The assembly also includes a deflection assembly configured to extend from the housing due to gravity and activation of a cover plate, with a deflector configured to disperse the fire exposure protection fluid over the one or more windows so as to wet the one or more windows.

This application relates to ventilation systems, more particularly to roof ventilation systems that help to protect buildings against fires. The roof vent has an ember impedance structure that impedes the entry of flames and embers or other floating burning materials while still permitting sufficient air flow to adequately ventilate a building. Several configurations of vents employing baffle members and fire-resistant mesh material are described, which can substantially prevent the ingress of floating embers and flames.

A fire protection door in an open position is present above a traveling path of a transport vehicle. The fire protection door is capable of moving downward from the open position to a closed position along a door trajectory. The transport vehicle includes: a control portion; an area detection portion that detects an interference area, which is an area in which a portion of the transport vehicle in the traveling path overlaps the door trajectory; and a descent detection portion that detects a descent of the fire protection door. The control portion performs a retraction control such that the transport vehicle travels to the outside of the interference area when the descent detection portion has detected a descent of the fire protection door in a state in which the transport vehicle is located in the interference area.

There is a temperature activated spring hinge comprising hinge section comprising at least one door leaf and at least one hinge leaf. There is also a fuse which is configured to react in response to an elevated temperature. The fuse can be positioned inside one of the knuckles of the door leaf. There is also a biasing element configured to bias the hinge in a closed position. In at least one embodiment the biasing element is a spring. There is also at least one guide configured to guide a movement of the hinge when the hinge moves from an open position to a closed position.

A ventilation closure system includes a damper, a shape memory alloy actuator, and a heating device. The shape memory alloy actuator is coupled to the damper. The shape memory alloy actuator has a first state in which the damper is positioned to permit airflow in the duct and has a second state in which the damper is positioned to obstruct the airflow in the duct. The shape memory alloy actuator is configured to change from the first state to the second state responsive to the shape memory alloy actuator attaining a first temperature responsive to heat released by an exothermic reaction in a compartment associated with the duct. The heating device is configured to heat the shape memory alloy actuator to maintain the damper in a position that obstructs the airflow in the duct.

An automatic smoke/carbon monoxide evacuation system for a garage equipped with a garage door and garage door opener with a motor is provided. The system includes a microprocessor, and a smoke/carbon monoxide sensor incorporated in a garage door reverse sensor of the garage door opener and coupled to the microprocessor, and configured to detect presence of smoke/carbon monoxide and send a trigger signal to the microprocessor in response to detecting smoke/carbon monoxide. The system further includes a power switch coupled to the motor and configured to automatically connect the motor to a power source in response to the trigger signal to automatically open the garage door to ventilate the detected smoke/carbon monoxide in response to the trigger signal. An alarm device is communicably coupled to the microprocessor and is configured to issue an alarm in response to the trigger signal.

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.
