    Abstract: An apparatus and concomitant method of reducing the number of synchronization pulses transmitted to the alarm units for increasing the reliability of the overall alarm system is disclosed. The synchronization signal is implemented as a reference or reset signal from which the alarm units derive a reference time to begin activation of the alarm units. Thus, when an alarm unit receives a reference synchronization pulse, the alarm unit applies the reference synchronization pulse as a reference point in time to trigger a series of flashes or audio tones. A second signal sent in close proximity to the synchronization signal is implemented to trigger a second function of the alarm units, such as a silence function.

  • Patent number: 7476013
    Abstract: A light bar is described that is of a modular construction based on one or more large circuit boards that are populated with light beam assemblies and then fastened to an interior space of the light bar housing. Keys that automatically align the light beam assemblies on each of the boards precisely control placement of the assemblies on the board. In turn, each of the boards is keyed to the interior of the light bar housing so that when the board is fastened to the housing the light beam assemblies are automatically registered into alignment with the lenses in the housing so that the beams from the assemblies are properly oriented. The light bar is inexpensive to fabricate and can be assembled quickly and reliably, yet it provides for a high degree of customization, which is a requirement in the emergency vehicle lighting industry.

  • Patent number: 6965203
    Abstract: Disclosed is a method and circuit for repetitively firing a flash lamp. The method utilizes a power supply having a periodic voltage signal. The method times the discharge of the flash lamp to occur when the power supply signal is below the flash lamp self extinguishing voltage such that the flash lamp de-ionizes while the power supply signal remains below the self extinguishing voltage, thus preventing afterglow. The circuit utilizes a means for detecting when the voltage of the power supply voltage signal falls below the self extinguishing voltage to trigger the flash lamp. An additional embodiment adds a means for interrupting current flow in the flash lamp before the voltage across a storage capacitor falls below said self extinguishing voltage. The method and circuit may be extrapolated for use with other electromechanical devices.

    Abstract: A user of a computer aided design (CAD) system graphically places fire alarm appliances, such as smoke detectors and sirens, in a drawing area. After elements are placed and physical paths are determined, a series of electrical circuit connections between alarm source elements and alarm appliance elements are determined. The electrical circuit connections define wire gauges and lengths passing through the physical paths. The wire types may be determined by predefined rules, and multiple wires may be placed in a single physical path. Subsequently, the CAD system performs electrical calculations associated with the alarm system. The electrical calculations may be based on a supervisory mode of operation as well as an alarm mode of operation. The resistance of wires in the alarm system may be based on a scaled wire length and/or a schematic (non-scaled) wire length. In one example, a backup battery capacity requirement is calculated.

    Abstract: An improved call system has a signal sending apparatus, a message receiving station located at a distance from the sending apparatus, and signal generating means located at the receiving station. The signal sending apparatus includes a call box for selectively energizing the generating means and producing a set of coded signals, each of which, when in communication with the receiving station, calling for a response which is determined by the specific message characteristics of the communicating signal. The signals may be generated in the form of light, sound or both, controlled in duration and intensity, and communication may be through electrical conductors, by radio, by telephone and other means.In one specific aspect the message receiving station may be a nurses call station in a hospital and the call box may be operated by a person in need of assistance in a hospital room or other area.

  • Patent number: 4155042
    Abstract: A disaster alert system is disclosed which consists of two major sub-systems. The first sub-system is a central disaster alert station which transmits coded R.F. activation signals specifying the geographic area and/or the official personnel to be alerted. Said central disaster alert station also transmits audio signals containing the disaster warning message to be disseminated to potential disaster victims and/or pre-selected official personnel.The second and companion sub-system consists of a plurality of independent and remotely located disaster alert modules which can be placed in any location to which disaster alert information is to be disseminated. Said disaster alert modules operate on continuous low-power standby, receiving and analyzing R.F. signals of a pre-determined carrier frequency and bandwidth. In the absence of said coded activation signal, said disaster alert modules remain in low-power standby.

  • Patent number: 4118694
    Abstract: A solid state code transmitter adapted for use with a conventional local fire alarm system in connection with installations that include a McCulloh loop circuit for the transmission of signals to a central proprietary fire alarm surveillance point. The transmitter circuit generates an electronic data word 17 bits long, the first 14 bits being field programmable by way of miniature DIP switches, each data word representing an equivalent of one round of generated code.
