Internal combustion engines (cars, forklifts, etc.) produce carbon monoxide (CO), an odorless, colorless and deadly gas. Operators of enclosed parking garages, warehouses, maintenance facilities, etc., can protect people by either ventilating, continuously or installing automatic fan control systems like the Macurco SS103 & DVP-120 Systems. Automatic fan control systems in parking garages normally have a short payback, because fans operate 1 to 2 hours a day rather than 24 hours a day. The CM-4 is powered from Macurco or other controllers, and provides a linear output to the controller. The CM-4 conforms to the specifications of most building codes, ASHRAE standards, and occupational health regulations. Typical codes require that CO exposure be 1: 35 ppm or less on the TWA (Time Weighted Average) basis over 8 hours, and 2: 200 ppm or less on the STEL (Short Term Exposure Limit) basis over a one hour period. Typical coverage is 5000 sq. ft. (464.5 sq. meters) per unit. . The CM-4 uses a long life solid-state sensor (7 – 10 year), which does not require regular re-calibration. The CM-4 replaces the SS102HC-1.
