The latest addition of the Gamewell-FCI’s Advanced Detection product line integrates four (4) complementary technologies into one device to convey accurate fire sensing information to locations where fire fighter response-time is critical. The Gamewell-FCI MCS4Warn is an advanced multi-criteria plugin detector that assembles four (4) unique sensing elements into one unit.

  • Electrochemical cell technology that monitors carbon monoxide (CO) produced by smoldering fires
  • Infrared (IR) sensing that measures ambient light levels and flame signatures
  • Photo-electric smoke detection
  • Thermal detection for temperature monitoring It is designed to be used with the Gamewell-FCI’s E3 Series® fire alarm control panel only.


The integration of continuous monitoring for all four major elements of a fire allows Gamewell-FCI to create a detector that responds more quickly to an actual fire with the highest immunity to nuisances. This advanced multi-criteria detector operates at a high immunity level. It is designed to detect changing elements, identify nuisance interference and adjust the sensor accordingly to reduce false alarms. Its on-board intelligence runs advanced algorithms that dynamically adjust detection parameters to respond to the inputs from the sensors, enabling instant response as ambient conditions change.

The panel automatically changes sensor thresholds, sensor gain, time, delays, combinations, sampling rates, and averaging rates. If any sensor fails, the detector automatically adjusts the sensitivity of the remaining sensors and produces a fault condition.

The CO cell has an expected lifetime of approximately six years. It is not a field replaceable component. An internal timer signals the control panel to signal the approach of the CO cell’s end of life. Upon expiration, you should contact the system supplier to arrange for replacement of the unit. Detection is not compromised when the CO cell expires. The algorithms automatically adjusts to properly weigh the inputs from the photo-electric, heat, and IR sensors..

Note: The CO cell is specifically deployed as a component of smoke detection in this device. This device is not Listed for applications in which the standalone CO detection is required for life safety.

The IR light sensor recognizes specific situations such as welding and makes adjustments rapidly to further reduce the potential for nuisance alarms. The thermal detection function uses thermistor technology with a software-corrected linear temperature response to offer exceptional nuisance alarm immunity and excellent fire detection.
