Claims20
An emergency evacuation system comprising:
- a system operator;
- and
- one or more emergency lighting units located in a building, wherein each emergency lighting unit comprises:
- a light indicator configured to be illuminated to indicate an exit of the building;
- a processor;
- communication circuitry configured to communicate with the system operator;
- and
- a visual sensor configured to capture motion data indicative of movement of one or more occupants present in an environment of the emergency lighting unit.
A method of monitoring occupancy with an emergency lighting unit comprising a light indicator illuminated to indicate an exit of a building, the method comprising:
- obtaining motion data generated by an visual sensor of the emergency lighting unit, wherein the motion data is indicative of movement of one or more occupants present in an environment of the emergency lighting unit;
- evaluating, by a processor of the emergency lighting unit, the motion data to monitor the environment of the light indicator;
- and
- updating, by the processor, an occupancy counter based on the evaluation of the motion data.
An emergency evacuation system comprising:
- a system operator;
- and
- one or more emergency lighting units located in a building, wherein each emergency lighting unit comprises:
- a light indicator configured to be illuminated to indicate an exit of the building;
- communication circuitry configured to communicate with the system operator;
- and
- an audio indicator configured to play an audio alert message in response to receiving an audio command from the system operator.
A method of broadcasting an audio alert message in a building using a plurality of emergency lighting units, each of the plurality of emergency lighting units comprising a light indicator illuminated to indicate an exit of the building, the method comprising:
- receiving, by each of the plurality of emergency lighting units, an audio command from a system operator;
- and
- playing, by each of the plurality of emergency lighting units, an audio alert message associated with the audio command in response to receiving the audio command.
