Claims19
A sprinkler comprising:
- a sprinkler body;
- a riser assembly:
- positioned in said sprinkler body;
- moving into, out of, and rotationally, relative to said sprinkler body;
- and,
- having a nozzle through which water flows during operation of said sprinkler;
- a main valve located within said sprinkler body;
- a body compartment located between an outer wall of said sprinkler body and said riser assembly;
- said body compartment having a compartment wall separating said body compartment into a first sub compartment and a second sub compartment;
- a cover that is removably disposed over said body compartment;
- a pilot valve located within said first sub compartment and configured to open and close said main valve;
- and,
- an electronics module located within said second sub compartment.
