摘要： A stack light with a light section having a housing with a plurality of at least partially translucent side walls and having a plurality of opposing light sources on longitudinally opposite ends of the housing to produce a very even blended light. A stack light system with one or more such light sections also includes a sound section having a hollow housing and a set of interchangeable acoustic chambers configured for insertion into the hollow housing, each chamber including a piezoelectric transducer and having a side wall structure configured to abut an inner side wall surface of the hollow housing, the chamber, transducer and housing together defining a resonant cavity. In one embodiment, an acoustic chamber has a longitudinally extending side wall and a substantially closed end wall, the side wall having adjacent the end wall a plurality of wide lateral openings spaced apart along its perimeter, the openings each having a width in the range of approximately 8-25% of the wavelength of the piezoelectric transducer's fundamental frequency.

摘要： A panel-mountable audible and visual warning device having an internal volume control shutter within a resonant cavity defined by the device housing and a sound generating element within the housing. Another embodiment has a cap on a main housing which fits into a hole in a mounting panel, with the cap external to the panel, the cap having multiple LEDs mounted therein in front of the panel face and behind and radially outward of a piezoelectric transducer so as to emit light directly forward past the transducer. Another cap embodiment has a piezoelectric transducer, LEDs, and a pushbutton switch mechanism including a movable surface portion of the cap's front wall and an internal set of switch contacts operably connected thereto. A control circuit can partially disable the alarm signaling function, such as by muting the transducer but continuing to energize the LEDs in response to actuation of the switch.

摘要： A wireless tandem alarm having a first alarm configured for physical connection to an industrial machine having an electronic machine controller, and a second alarm configured for detachable connection to the first alarm or to the industrial machine. Each alarm has a housing, a piezoelectric transducer within the housing, a processor configured to drive the piezoelectric transducer in response to a control signal, and a wireless transceiver configured for relatively short-range, low-power communications. In the first alarm, the processor drives the piezoelectric transducer in response to a signal from the machine controller and, also responsive to the machine controller signal, transmits a control signal via the wireless transceiver. In the second alarm, the wireless transceiver receives the control signal from the first alarm and supplies it to the processor, which is configured drive the piezoelectric transducer in response. The alarms are configured to work in tandem, when attached to each other, to cooperatively produce a combination of sound characteristics not achievable with either alarm alone. The alarms are also configured to detect when they are detached from each other and to respond by changing one or more sound characteristics. When detached, the alarms are also capable of affecting the operation of each other via two-way wireless communications.

摘要： Piezoelectric alarm devices are held in a plastic housing with flat bladed electrical terminals carried on the outside of the housing. These terminals are being replaced by a pluggable terminal block assembly which can be readably integrated into the housing. The assembly includes a header which is encapsulated in the housing.

摘要： The invention is an modified audible signal, such as a piezoelectric noise-making and audible signaling device, which further includes a hydrophobic covering material, such as polytetrafluoroethylene (PTFE). The hydrophobic covering material is known to be water resistant, but does not effect the sound of the audible signaling device, thereby delaying or preventing the failure of the audible signaling device from water corrosion.
