The SUS-to-ISI WatchDogs IPC communication is currently bypassed with a constant in SUS's MC1 and MC3 models. The constant is 0, which correspomds to OK state of SUS. A screen-shot of these models is attached.

In this configuration, MC1 and MC3 cannot trip HAM2-ISI. In order to safely actuate on HAM2-ISI, this constant needs to be removed, and connections need to be made in the following models: 

• h1susmc1.mdl
• h1susmc3.mdl

Note: These constants were put in to avoid tripping HAM2-ISI during the chamber-side tesing of MC1 and MC3.
