The Sensaphone Stationsitter provides the same monitoring power as the Sensaphone 1800 but with the addition of duplex pump control logic for industrial Fill and Drain applications. The Stationsitter features eight input channels for NO/NC contact, 4-20mA transducers, and temperature sensors, as well as a universal output relay. Alarm messages are delivered via voice phone calls, and as text messages to alphanumeric pagers and cell phones. Individual user-codes track who responds to alarms.
