## Abstract

A wall-mountable spray head unit is shown with a display and/or at least one user input device. The wall-mountable spray head unit is shown deployed in a fire suppression system that includes at least one or at least two wall-mounted spray head units capable of aiming and shooting fire suppressant liquid into a fire.

## Claims

### Claim 1

A wall-mountable spray head unit comprising:
a display and at least one user input device; and
a rotatable spray head assembly comprising:
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.

### Claim 2 (depends on 1)
