Like the 1400, the 1800’s voice phone calls are customized so that users can hear each alarm described in detail and in their own voice. The 1800 is perfect for ultra-low freezer monitoring all the way down to -85°C. Also, a built in system identifies who responds to any alarm phone call and tracks respondents with a history log.
The 1800 includes an output relay so that a local device can be switched on when an alarm occurs, as well as a line-seizure feature. LEDs on the face of the units afford local indication of alarm and status conditions. And an additional input type, 4–20mA, not supported in the 400, is available in the 1800. The 1800 is also capable of alphanumeric paging.
