1. model preparation:

1. Structure code:

Code A: indicates that the inclination angle of the water curtain is 0 °.

Code B: indicates that the inclination angle of the water curtain is 90 ° and there is only one water outlet.

Code C: indicates that the inclination angle of the water curtain is 90 ° and there are two outlets.

Code D: indicates that the inclination angle of the water curtain is not 0 ° or 90 °.

2. Usage feature code:

Code G: It is only applicable to water curtain nozzle for fire separation.
