Strobe notification appliance with directional information
View Patent ↗A strobe notification appliance that outputs directional information is disclosed. The strobe notification appliance may generate, in addition to notification of the fire condition, directional information (e.g., such as away from the unavailable exit paths and/or toward the preferred exit paths). In one instance, the strobe notification appliance includes a strobe element (such as a flash tube strobe element or LED strobe element) outputting fire notification information and a directional light element (such as one or more LEDs) outputting directional information. In another instance, the strobe notification appliance includes the strobe element that outputs both fire notification information and directional information. In this way, occupants of a building may be notified of a fire and notified of available or unavailable exit paths.

6. The strobe notification appliance of claim 2 , wherein the command to activate the strobe notification appliance comprises an indicator of movement in a rightward direction or a leftward direction relative to the strobe notification appliance;
wherein the controller is configured to control the one or more LEDs to convey the directional information by:
determining, based on the indicator, a color for the one or more LEDs, the color indicative of the movement in the rightward direction or the leftward direction relative to the strobe notification appliance; and
controlling the one or more LEDs to output the color.
7. The strobe notification appliance of claim 6 , wherein the controller is configured to determine the color indicative of the directional information from a plurality of colors, one of the plurality of colors indicative of not going in the rightward direction or leftward direction and another of the plurality of colors indicative of going in the rightward or leftward direction.
8. The strobe notification appliance of claim 1 , wherein the second light emitting elements are positioned on the front face of the strobe notification appliance and are visible to the occupant.
9. The strobe notification appliance of claim 1 , wherein the controller is configured to control the second light emitting elements in a first configuration so that the directional information is indicative to the occupant to move in a leftward direction relative to the strobe notification appliance; and
wherein the controller is configured to control the second light emitting elements in a second configuration so that the directional information is indicative to the occupant to move in a rightward direction relative to the strobe notification appliance.
10. The strobe notification appliance of claim 1 , wherein the second light emitting elements comprise a first LED and a second LED;
wherein light output from the first LED is indicative to the occupant whether to move in a rightward direction relative to the strobe notification appliance; and
wherein light output from the second LED is indicative to the occupant whether to move in a leftward direction relative to the strobe notification appliance.
11. The strobe notification appliance of claim 1 , wherein the second light emitting elements comprise a first LED and a second LED;
wherein light output from the first LED is indicative to the occupant whether or not to move in a rightward direction relative to the strobe notification appliance; and
wherein light output from the second LED is indicative to the occupant whether or not to move in a leftward direction relative to the strobe notification appliance.
12. The strobe notification appliance of claim 11 , wherein a first color output from the first LED is indicative to the occupant to move in a rightward direction relative to the strobe notification appliance;
wherein a second color output from the first LED is indicative to the occupant not to move in a rightward direction relative to the strobe notification appliance;
wherein a first color output from the second LED is indicative to the occupant to move in a leftward direction relative to the strobe notification appliance; and
wherein a second color output from the second LED is indicative to the occupant not to move in a leftward direction relative to the strobe notification appliance.
13. The strobe notification appliance of claim 1 , wherein the second light emitting elements are in a form of an arrow.
14. The strobe notification appliance of claim 13 , wherein the arrow is pointing in a direction; and
wherein activation of the second light emitting elements in the form of an arrow is indicative to the occupant to travel in the direction.
15. The strobe notification appliance of claim 1 , wherein when the strobing light and the light indicative of directional information is output simultaneously, the light indicative of directional information is visible to an occupant separate from the strobing light, the strobing light comprises white light and the light indicative of directional information comprises non-white light.
16. The strobe notification appliance of claim 1 , wherein the directional information is configured to convey the direction for the occupant to go.
17. The strobe notification appliance of claim 1 , wherein the directional information is configured to convey the direction for the occupant not to go.
18. The strobe notification appliance of claim 1 , wherein the directional information is configured to convey the direction for the occupant to go and the direction for the occupant not to go.
19. The strobe notification appliance of claim 1 , wherein the directional information is configured to convey the indication to stay in place.
20. The strobe notification appliance of claim 1 , wherein the first light emitting element comprises a flash tube strobe element.
