1. A hazard detector, comprising:

  • a case, the case having an interior and a plurality of exterior surfaces, wherein the interior of the case houses components of the hazard detector, a first exterior surface of the plurality of exterior surfaces is configured to mount with a wall or ceiling, and a second exterior surface of the plurality of exterior surfaces, located on an opposite side of the case from the first exterior surface;

    a plurality of hazard sensors housed in the interior of the case, the plurality of hazard sensors detect the presence of a plurality of types of hazards;

    a user input component to receive user input, the user input component being located on the second exterior surface of the case;

    a light that emits light, the light comprising a plurality of lighting elements, wherein;

    the light is capable of illuminating in a plurality of colors and a plurality of animation patterns; and

    when the plurality of lighting elements is illuminated, light output by the light continuously encircles, on the second exterior surface of the case, an edge of the user input component;

    a presence sensor; and

    a processing system in communication with the plurality of hazard sensors, the user input component, the presence sensor, and the light, the processing system comprising at least one processor that is configured to;

    determine a state of the hazard detector;

    cause the light to illuminate using at least one color of the plurality of colors and an animation pattern of the plurality of animation patterns in response to the determined state of the hazard detector;

    receive information indicative of a user presence from the presence sensor while causing the light to illuminate using the at least one color and the animation pattern; and

    alter the animation pattern used to illuminate the light in response to receiving the information indication of the user presence.
