Hi All,

in my new project some of the existing building done by simplex 4100U and now i am doing EST-3 for new buildings.both the panels located in same fire command center room.my question is i need to monitor the fault and alarm signal from the existing panel simplex.

pls guide me what r the ways to interface EST-3 and Simplex panels.

Do you want the Simplex to monitor the EST, or the other way around? Which panel will be communicating to central station with a DACT?

hi,
put dry contact relay module from the simplex and receive the signal by input module of EST 3.
the number of the relay module depend on the number of the signal you need to receive form the SIMPLEX panel.
