a rotatable spray head assembly which comprises:
a spray manifold rotatable about a first axis; and
a spray nozzle supported by the spray manifold and orientated to deliver a mist of fire-suppressant material radially in a plane defined by the first axis and a second axis which is perpendicular to the first axis;
a non-rotatable faceplate that, when the spray head unit is installed in a wall, is parallel to the wall and the first axis;
at least one sensor fixed in the faceplate;
wherein the rotatable spray head assembly does not support a sensor;
and wherein the faceplate comprises:
an aperture through which the spray nozzle protrudes when delivering the mist; and
a faceted projection comprising at least one face, wherein the at least one face is orientated off normal to the faceplate for facing a respective side of a room and supports one or more sensors oriented normal to the face.
