Features

  • Applies four separate sensing elements.
  • Has the highest nuisance alarm immunity.
  • Employs advanced algorithms that interpret and respond to multiple inputs.
  • Uses six levels of sensitivity.
  • Incorporates CO sensing for the fastest response to slow developing, smoldering fires.
  • Comprises fully integrated infrared sensing to support a quick fire alarm response.
  • Provides the automatic drift compensation of a smoke sensor and a CO cell.
  • Offers superior EMI protection.
  • Includes twin LED indicators that provide 360 visibility.
  • Programs LEDs to be panel controlled to blink, latch-on, or latch-off.
  • Contains a built-in test switch. MCS-4-Warn 7272-1703:0173 SIGNALING S1195

9021-60672 Rev. D page 2 of 2 www.gamewell-fci.com Description (Continued) Note: The CO cell is specifically deployed as a com- ponent of smoke detection in this device. This device is not Listed for applicatio ns 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 technol- ogy with a software-corrected linear temperature response to offer exceptional nuisance alarm immu- nity and excellent fire detection. MCS-4-Warn Advance Multi-Criteria Detector Specifications Physical Specifications Base Diameter: 4.0” (10.16 cm) Base Height: 2.4” (6.1 cm) Shipping Weight: 4.6 ounces Operating Temperature Range: 32° F to 100° F (0° C to 38° C) Operating Humidity Range: 10 to 93% relative humidity (non-condensing) Electrical Specifications External Supply Voltage: 15 to 32 VDC Standby Current: 200 µA at 24 VDC (no communications) Alarm Current (LED on): 7 mA at 24 VDC Sensitivity Settings & Suggested Applications Level 1: 1% per foot (30.48 cm) of smoke. Very clean environments: Used in Laboratories. Level 2: 2% per foot (30.48 cm) of smoke. Clean environments: Used in offices. Level 3: 3% per foot (30.48 cm) of smoke. Moderately clean environments: Used in hotel rooms, dorm rooms. Level 4: 3% per foot (30.48 cm) of smoke with different algorithm process- ing and weighting of sensor ele- ments. Used in hotel rooms near a shower or boiler rooms. Sensitivity Settings & Suggested Applications (Continued) Level 5: 4% per foot (30.48 cm) of smoke. Used in equipment rooms, kitchens, paint shop. Level 6: Thermal alarm at 135° F (57° C) Note: After the CO cell has reached the end of life, any device set to Level 3 or Level 4 will default to Level 5 and Level 5 will drop to 3%. The following sensitivities apply to devices with expired CO cells. Level 1: 1% per foot (30.48 cm) of smoke. Very clean environments: Used in Laboratories. Level 2: 2% per foot (30.48 cm) of smoke. Clean environments: Used in offices. Level 5: 3% per foot (30.48 cm) of smoke. Moderately clean environments: Used in hotel rooms, dorm rooms. Level 6: Thermal alarm at 135° F (57° C)
