A receiver for a fire suppression system includes a receiving portion configured to receive and couple with a corresponding portion of a cartridge. The receiver includes a translatable member configured to engage a corresponding portion of the cartridge and translate in response to insertion of the cartridge. The receiver includes a switch configured to transition between a first state and a second state in response to translation of the translatable member to indicate whether the cartridge is inserted into the receiving portion.

A fire door system is disclosed herein. The fire door system comprises a door and a door control unit coupled to the door. A plurality of sensors is configured on the door or adjacent the door. A controller is coupled to the door control unit and the plurality of sensors. The controller facilitates activation of the motorized door unit for maintaining the door in a closed position subsequent to sensing of a surrounding temperature by the plurality of sensors, wherein the surrounding temperature is greater than a threshold temperature.

A heat sensor includes a base and a heat sensor body. The base is to be mounted onto a mounting surface of a building. The heat sensor body has a bottomed cylindrical shape and is to be attached to the base. The heat sensor body includes an opening, a board, a heat detection unit, and at least one wall member. The at least one wall member controls flow of a gas to cause the gas that passed through the opening to flow toward the heat detection unit. The at least one wall member separates the flow of the gas that has entered the heat sensor body from an external space through the opening into a plurality of gas flows and directs one of the plurality of gas flows, which has been separated to flow beside an inner surface of the heat sensor body, toward the heat detection unit.

The present invention relates to: a smart fire-extinguishing device for automatically performing a fire-extinguishing operation by detecting the outbreak of a fire; and a smart fire-extinguishing system including same, and provides a smart fire-extinguishing device comprising: a chemical storage part in which fire-extinguishing chemicals are filled; a fuse part for exhibiting explosive force so that the fire-extinguishing chemicals of the chemical storage part are jetted to the outside; and a fire detection part, which detects at least one from among temperature, flames and smoke, compares a detection result with a pre-set fire outbreak reference value so as to determine whether a fire breaks out, and operates the fuse part according to a determination result so as to jet out the fire-extinguishing chemicals.

A fire detection system (10) includes a plurality of smoke detectors (14) positioned for detection of smoke within one or more smoke detection volumes (12a, 12b). The fire detection system (10) is configured to monitor occupancy of the smoke detection volumes (12a, 12b) or to receive data indicative of occupancy of the smoke detection volumes (12a, 12b), for example from an intrusion detection system (20). The fire detection system (10) is configured to adjust a smoke sensitivity associated with each of the smoke detectors (14) based on the occupancy of the respective smoke detection volume (12a, 12b), with the smoke sensitivity being decreased when the respective smoke detection volume (12a, 12b) is occupied.
