Abstract
An exit path indicating device incorporates at least a first port for receiving an alarm indicating signal. In normal operation upon receipt of the alarm indicating signal, the device outputs verbal and non-verbal indicators of the presence of an alarm condition for use in evacuating the region. A second port disables the non-verbal outputs. The second port can be coupled to a local sensor which provides an indication of a hazardous or alarm condition adjacent to or on the exit or egress path. If the sensor is indicating the presence of a hazardous or alarm condition, the non-verbal outputs can be disabled, while verbal directions can continue to be emitted.
Claims26
An alarm indicating sounder comprising:
- a directional audible output device which when activated emits directional audible, non-verbal alarm indicating indicia;
- an input port for receipt of alarm indicating control signals to activate the output device;
- a transducer for emitting predetermined, verbal messages associated with an alarm condition;
- control circuitry coupled to the output device, the input port, and the transducer, the control circuitry, responsive to a received alarm indicating control signal, activates the directional output device to emit the directional alarm indicating indicia and the transducer to emit at least one predetermined message, where the message can be emitted in the absence of the directional alarm indicating indicia.
A system comprising;
- an output device that provides at least two different audible outputs, one being a verbal the other being a non-verbal output, both outputs are indicative of an alarm condition, the device having an output disabling control port;
- and
- an ambient condition detector, the detector having at least one alarm output indicative of the presence of a predetermined alarm condition, the alarm output is coupled to the control port to at least intermittently disable the non-verbal output of the device in the presence of the predetermined alarm condition.
A method comprising:
- determining that a hazardous condition is present in a region;
- providing indicia indicative of at least one exit path from the region;
- and
- determining if a hazardous condition is present in the vicinity of a portion of the exit path, and, responsive thereto, selectively providing directional non-verbal audio and verbal audio outputs in the vicinity of the path.
