The CAP can access a maximum of 80 EC Gold transmitters assigned to up

to 8 zones and set Sensor Fault, High-High, High, and Low alarms based on

ppm values read from the transmitters. In addition, the maximum and

average ppm values are reflected on two optional 4-20mA outputs per zone.

USER INTERFACE

Calibration and setup 4 Line x 20 char LCD and 4X4 membrane keypad.

Network RS-485 Modbus protocol connection to EC Gold sensors. Optional additional
