AN ALARM SHALL BE INITIATED AT THE BMS OPERATOR WORKSTATION. IF SMOKE ISDETECTED IN THE SUPPLY DUCT, THE SUPPLY FAN SHALL SHUT DOWN AND AN ALARM SHALL BE INITIATEDAT THE BMS OPERATOR WORKSTATION. ON A LOSS OF CONTROL SIGNAL TO THE CHANGEOVER COIL VALVE, THE VALVE SHALL FULLY OPEN TO THE COIL.7. DEMAND CONTROL VENTILATION: A CO2 SENSOR LOCATED IN THE UNIT RA DUCTWORK SHALL MODULATE THE OUTSIDE AIR DAMPER TO MAINTAIN A RETURN AIR CO2 LEVEL OF 800 PPM (ADJ). IF THE CO2LEVEL IS BELOW THRESHOLD, THE OUTSIDE AIR DAMPER SHALL OPEN TO ITS ABSOLUTE MINIMUM POSITION(80 CFM FOR AHU-2 AND 100 CFM FOR AHU-4).22DUCTWORK DIMENSIONS INDICATED ARE CLEAR INSIDE DIMENSIONS.23ALL AIR HANDLING UNITS >2000 CFM SHALL HAVE A DUCT MOUNTEDSMOKE DETECTOR INSTALLED IN THE AIRSTREAM.24ALL SMOKE DAMPERS SHALL BE COMBINATION SMOKE/FIRE DAMPERS SHALLSHALL BE MOTOR OPERATED WITH 24VOLT/120 VOLT ACTUATOR BY HVACCONTRACTOR.
