Wall-mounted spray head unit

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 fire-suppressant material radially in a plane defined by the first axis and a second axis which is perpendicular to the first axis;
• and
• one or more fire-locating sensors including a visible-light camera, or a microphone, or both a visible-light camera and a microphone;
• at least one output device including a first output device, wherein the at least one output device is integrated into a faceplate of the wall-mountable spray head unit;
• a controller configured to cause the first output device to output real-time information;
• and
• at least one input device including a first input device integrated into the faceplate, wherein the spray head unit is configured to cease deployment of the fire-suppressant material in response to a user input to the first input device within a pre-set period.
