Abstract
A wall-mountable spray head unit (11) is described. The spray head unit comprises a rotatable spray head assembly (8) which comprises a spray manifold (18) rotatable about a first axis (17), a spray nozzle (19) supported by the spray manifold and orientated to deliver a mist of fire-suppressant material radially in a plane in a plane defined by the first axis and a second axis which is perpendicular to the first axis. The spray head unit includes a sensor (20) and/or an interface (35) for receiving a sensor signal from an external sensor and/or a control signal from an external controller. The rotatable spray head assembly does not support a sensor.
Claims18
A wall-mountable spray head unit comprising:
- 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.
