REPLACED BY CM-6
The CM-1 B is a Carbon Monoxide Meter, Alarm and Controller. It is an all-electronic system using a microprocessor to measure the quantity of Carbon Monoxide (CO) and calculate the danger level, which is a combination of level of CO and time exposure
A three digit lighted display on the CM-1B shows the current level of CO between 0 and 250 parts per million (PPM). The CM-1B continuously monitors the air, and updates the display every 2.5 minutes.
The microprocessor analyzes this data and compares it to the 10% Hemoglobin concentration, which is stored in the computer memory. If the danger level is exceeded, the alarm sounds and the alarm relay closes. The fan relay actuates if the average level of CO exceeds 35 PPM for 5 minutes.
