Industry:Fire safety
A system component that accepts and displays signals from digital alarm communicator transmitters (DACTs) sent over the public switched telephone network.
Industry:Fire safety
A system component composed of two subcomponents: one that receives and decodes radio signals, the other that annunciates the decoded data. These two subcomponents can be coresident at the central station or separated by means of a data transmission channel.
Industry:Fire safety
A system component at the protected premises to which initiating devices or groups of devices are connected. The DACT seizes the connected telephone line, dials a preselected number to connect to a DACR, and transmits signals indicating a status change of the initiating device.
Industry:Fire safety
A system component at the protected premises to which initiating devices or groups of devices are connected that transmits signals indicating a status change of the initiating devices.
Industry:Fire safety
A system capable of decelerating the vehicle at a controlled rate to a desired, reduced speed or complete stop.
Industry:Fire safety
A system based on one or more central processing units (CPUs), connected to sensors or actuators, or both, for the purpose of control or monitoring.
Industry:Fire safety
A syndrome due to evolved gas in the tissues resulting from a reduction in ambient pressure.
Industry:Fire safety
A switchgear assembly completely enclosed on all sides and top with sheet metal (except for ventilating openings and inspection windows) and containing primary power circuit switching, interrupting devices, or both, with buses and connections. The assembly may include control and auxiliary devices. Access to the interior of the enclosure is provided by doors, removable covers, or both. Metal-enclosed power switchgear is available in non-arc-resistant or arc-resistant constructions.
Industry:Fire safety
A switch that usually is driven directly by the fan wheel or fan motor shaft and in which a switch contact closes when the speed of the fan shaft or drive motor reaches a certain predetermined rate.
