Abstract: 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.

Abstract: A fire alarm activation system 1 includes: a sensing device 2 configured to detect removal of a fire extinguisher 4, and a manual call point 3 in communication with the sensing device 2. Detection of a removal of the extinguisher by the sensing device 2 will trigger an alarm condition of the manual call point 3. The alarm condition of the manual call point 3 can also be triggered manually by a user.

Abstract: Disclosed is a smoke detector having a controller configured for executing an operational test, the operational test including: activating an electronic vaporizer to produce vaporized particulate within the smoke detector; rendering a first determination of whether a particulate sensor disposed in the detector senses the vaporized particulate; and rendering a second determination based on the first determination, the second determination identifying an operational state of the smoke detector.

Abstract: A detection circuit for use in detecting hazardous conditions includes a first conductor (142) and a second conductor (144). The first conductor and the second conductor couple at least one initiating device (138) to a detection control panel (104) configured to detect hazardous conditions. A voltage-stabilizing device (140) is configured to stabilize a voltage between the first conductor and the second conductor. A method of assembling a detection system includes coupling a first conductor and a second conductor to at least one initiating device to form a detection circuit, and coupling a voltage-stabilizing device to the first conductor and the second conductor, wherein the voltage-stabilizing device is configured to stabilize a voltage between the first conductor and the second conductor. The first conductor and the second conductor are coupled to a detection control panel configured to detect a hazardous condition.

Abstract: An elbow rotator apparatus for rotating an integrally formed section of an elbow workpiece includes a pair of gripping arms which are selectively positionable in a first position displaced from the elbow workpiece, and a second position in which the gripping arms are in contact with the integral section of the elbow workpiece. A rotary actuator is operatively connected to the gripping arms to selectively rotate the gripping arms by a predetermined amount when the gripping arms are in the second position.
