Abstract
A wall-mountable spray head unit (11) is described. The spray head unit comprises a rotatable spray head assembly (81, 82; FIG. 9, 83; FIG. 17) which comprises a spray manifold (181, 182; FIG. 9) rotatable about a first axis (17), a spray nozzle (19) supported by the spray manifold and orientated to deliver 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, and at least one thermal sensor (20).
Claims34
A wall-mountable spray head unit (11) comprising:
- a rotatable spray head assembly (81, 82, 83) which comprises:
- a spray manifold (181, 182) rotatable about a first axis (17);
- and
- a spray nozzle (19) supported by the spray manifold and orientated to deliver fire-suppressant material radially in a plane defined by the first axis and a second axis which is perpendicular to the first axis;
- and
- at least one thermal sensor (20) configured to sense in the plane.
A spray head unit according to any preceding claim, wherein the spray manifold is only rotatable about the first axis.
A spray head unit according to any preceding claim, further comprising:
- an inlet port in fluid communication with the nozzle.
A spray head unit according to any preceding claim, wherein the, or each thermal sensor, comprises an infrared thermometer.
A spray head unit according to any preceding claim, wherein the, or each thermal sensor, comprises an infrared camera or array of discrete infrared sensors.
A spray head unit according to any preceding claim, wherein the spray manifold includes a face and wherein the spray nozzle and the at least one thermal sensor are set in face.
A spray head unit according to any preceding claim, wherein the spray nozzle and the thermal sensor are offset in a direction parallel to the first axis.
A spray head unit according to any preceding claim, further comprising:
- an actuator configured to cause rotation of the spray manifold about the first axis.
A spray head unit according to any preceding claim, comprising two or more nozzles.
A spray head unit according to any preceding claim comprising:
- an enclosure having an aperture,
- wherein the rotatable spray head assembly is housed or mainly housed in the enclosure.
A spray head unit according to any preceding claim, wherein the rotatable spray head assembly comprises:
- a gate valve;
- wherein the rotatable spray head assembly is arranged such that, in a parked position, the gate valve is closed.
A spray head unit according to any preceding claim, further comprising:
- a control unit operatively connected to the at least one thermal sensor and configured to control rotation of the rotatable spray head assembly.
A spray head unit according to any preceding claim, configured, in use, to sweep the rotatable spray head assembly (81, 82, 83) through an angular range around the first axis of at least 120°.
A spray head unit according to any preceding claim, configured to deliver the fire-suppressant material in arc in the plane of at least 2×25°.
A spray head unit according to any preceding claim, configured to deliver a mist of the fire-suppressant material.
A spray head unit according to any preceding claim, wherein the fire-suppressant material is water or is a mixture containing water.
A fire suppression system comprising:
- at least one wall-mountable spray head unit according to any preceding claim, which is wall mounted;
- at least one pressure generator for supplying fire suppressant material to the at least one wall-mountable water under pressure;
- and
- at least one activation device which, in response to an activation signal, causes fire suppressant material to spray out from the spray head(s) of the at least one wall-mountable spray head unit.
