The MarleyGard LINK provides an interface between a Building Management System (BMS) and a Marley control panel to monitor cooling tower status points and analog readings using BACnet/IP LAN systems. The MarleyGard LINK communications panel provides a pre-programmed interface module and a set list of status points. The status of various cooling tower components can then easily be monitored using a BMS including:

• Gearbox oil level
• Cold water basin level controls
The MarleyGard LINK may be packaged with a Marley cooling tower control panel or offered as an aftermarket solution to a Marley control panel.
