Abstract: Systems, methods, and devices for hazard detection are described. A hazard detection device may include a printed circuit board. The hazard detection device may further include a chassis that provides a housing for components of the hazard detection device; a smoke chamber that is mid-mounted; a carbon monoxide sensor that is mounted with the circuit board; and a speaker assembly that partially encircles the mid-mounted smoke chamber.
