Method and apparatus to aide in emergency egress
A method and apparatus are provided to aide in emergency egress of a structure. More particularly, egress indicators are co-located with hazard sensors. During detection of a hazard condition, locations of sensors detecting the hazard are identified and a pathway directing traffic away from the hazard is determined. Finally, the egress indicators are operated to direct traffic down the determined pathway.
1. A method for operating an emergency egress system, the method comprising the steps of:
receiving a plurality of hazard indications;
identifying locations of sensors detecting the hazard;
determining a path away from the hazard based on locations of the sensors detecting the hazard; and
sequencing a plurality of ceiling panel lights to direct traffic towards the path, wherein the plurality of ceiling panel lights are co-located with the sensors.
2. The method of claim 1 wherein the step of receiving the plurality of hazard indications comprises the step of receiving a wireless transmission from at least one hazard detector.
3. The method of claim 1 wherein the step of receiving the plurality of hazard indications comprises the step of receiving a wireless transmission from at least one hazard detector, and wherein the hazard detector is taken from the group consisting of a smoke detector, a heat detector, a flood/water detector, a chemical detector, a hazardous gases or byproducts detector, and a radiation detector.
4. The method of claim 1 wherein the step of controlling a plurality of ceiling panel lights comprises the step of wirelessly controlling the plurality of ceiling panel lights.
5. An apparatus comprising:
a receiver for wirelessly receiving an indication of a hazard condition;
logic circuitry for identifying locations of sensors detecting the hazard, determining a path away from the hazard based on locations of the sensors detecting the hazard; and
a transmitter for wirelessly sequencing a plurality of ceiling panel lights to direct traffic towards the path, wherein the plurality of ceiling panel lights are co-located with the sensors.
6. The apparatus of claim 5 wherein the indication of the hazard comprises an indication of smoke, heat, flood/water, chemicals, gases, or radiation.
7. A method comprising the steps of:
detecting a hazard;
wirelessly notifying a centralized controller of the hazard;
receiving a message from the centralized controller in response to the notification; and
sequencing ceiling panel lights based on the received message.
8. An apparatus comprising:
hazard detection circuitry;
a wireless transmitter for wirelessly notifying a centralized controller when hazard detection circuitry detects a hazard;
a wireless receiver for receiving messages from the centralized controller;
an egress path indicator; and
logic circuitry for sequencing ceiling panel lights based on the messages received from the centralized controller.
9. The method of claim 1 wherein the step of sequencing the plurality of ceiling panel lights comprises the step of wirelessly transmitting instructions to the plurality of lights causing them to sequence.
10. The apparatus of claim 7 wherein the step of sequencing the ceiling panel lights comprises the step of wirelessly transmitting instructions to the plurality of lights causing them to sequence.
11. The apparatus of claim 8 wherein the logic circuitry sequences the ceiling panel lights by wirelessly transmitting instructions to the of lights causing them to sequence.
