IS "OFF" D-1, FSD-1 AND FSD-2 SHALL BE FULLY CLOSED. WHEN

UNIT IS "ON" FSD-1 AND FSD-2 SHALL BE FULLY OPEN. D-1 AND D-2

SHALL MODULATE IN ACCORDANCE WITH THE FOLLOWING SEQUENCE:

THE SUPPLY AIR TEMPERATURE, SENSED BY T-1, SHALL BE MAINTAINED

AT SETPOINT BY DCP MODULATING V-1 OR D-1, D-2 AND V-2

IN SEQUENCE.

THE DCP USING TOTAL SUPPLY AIR AND RETURN AIR FLOW SIGNALS SHALL

IF THE AIR TEMPERATURE AS SENSED BY T-3 FALLS BELOW 45°F, AN

ALARM SIGNAL SHALL BE INDICATED AT THE DCP AND ECC. IF THIS

TEMPERATURE FALLS BELOW 40°F, THE UNIT SUPPLY AND RETURN FANS

SHALL SHUT "OFF" AND A CRITICAL ALARM SHALL BE INDICATED AT THE

DCP AND ECC.

THE SUPPLY AIR FLOW SHALL BE CONTROLLED BY THE DCP MODULATING

SUPPLY FAN VARIABLE SPEED MOTOR CONTROLLER (VSMC) TO MAINTAIN

THE DUCT STATIC PRESSURE SETPOINT (SET AT 0.75 INCHES STATIC

PRESSURE) AS SENSED BY SPS STATIC PRESSURE SENSOR (SEE PLANS

FOR LOCATION).

WHEN THE TEMPERATURE OF THE OUTSIDE AIR, SENSED BY T-2, IS BELOW

THE SUPPLY AIR TEMPERATURE, SENSED BY T-1, THEN DAMPERS D-1M

SHALL BE FULLY OPEN, DAMPERS D-1 AND D-2 SHALL MODULATE

TO MAINTAIN THE SCHEDULED SUPPLY AIR TEMPERATURE. IF D-2 IS

OPEN, D-1 AND D-3 ARE CLOSED THEN V-2 SHALL MODULATE OPEN TO

MAINTAIN THE SUPPLY AIR TEMPERATURE. SET POINT AS SENSED BY T-1.

WHEN THE TEMPERATURE OF THE OUTSIDE AIR, SENSED BY T-2, IS

BETWEEN 65°F AND THE SUPPLY AIR TEMPERATURE SETPOINT T-1, DAMPER

D-2 SHALL BE FULLY CLOSED AND D-1, D-1M SHALL BE FULLY

OPENED (MAXIMUM OUTSIDE AIR POSITION). THE DCP SHALL MODULATE

V-1 TO MAINTAIN THE SUPPLY AIR TEMPERATURE, SENSED BY T-1.

WHEN THE TEMPERATURE OF THE OUTSIDE AIR, SENSED BY T-2, IS ABOVE

65°F, THE DCP SHALL OPEN D-1M TO MINIMUM POSITION, D-2 SHALL BE

FULLY OPEN, D-1 SHALL BE CLOSED. THE DCP SHALL MODULATE

V-1 TO MAINTAIN THESUPPLY AIR TEMPERATURE, SENSED BY T-1.

OUTSIDE AIR FLOW SHALL BE MEASURED BY AN AIR FLOW MEASURING

STATION LOCATED IN THE MINIMUM OUTSIDE AIR DUCT.

WHEN SMOKE IS DETECTED BY DUCT SMOKE DETECTORS F SD SHOWN

ABOVE, THE SUPPLY AND RETURN FANS SHALL SHUT "OFF" AND AN ALARM

SIGNAL SHALL BE TRANSMITTED TO THE FIRE ALARM SYSTEM. FOR ALARM

PURPOSES ONLY ALL FIRE/SMOKE DAMPERS IN THE SUPPLY AND RETURN

DUCTS SHALL CLOSE. EXHAUST FANS SERVING SPACE OF SUPPLY FAN

SHALL CONTINUE TO RUN. SUPPLY AND RETURN FANS SHALL RESTART AND

FIRE/SMOKE DAMPERS SHALL OPEN WHEN FIRE ALARM CIRCUIT IS RESET.
