Wheelock Safepath Wiring

Does anyone have experience with the Wheelock Safepath system? I have an older SCSP-4RP panel with the MDX-2 card. Trying to determine the wiring for initiation from the FACP. As of now, I get audio out when keying mic and when putting panel into manual mode, I get tone only, no voice. First time with this model of VEP.

I’d recommend searching for the manual online. If the internet doesn’t have anything, then you could consider contacting Eaton for a manual, but make sure to specify it’s a discontinued model.
