SJE-Rhombus Tank Alert AB Septic Alarm in ST

I have SJE Rhombus Tank Alert AB installed as a septic alarm. I was wondering if it is possible to somehow attach it ST with another device. Thanks

Bringing this back from the dead…I have some MFG Tank Alert 1. Would like to do the same thing. Manual says switching circuit is low voltage and isolated from the main power. Also says the circuit can handle 12v @ 1amp.

Anyone?
