ATC GENERAL NOTES

1. THE ATC WORK SHALL INCLUDE PROVISIONS FOR A COMPLETE AND OPERABLE CONTROL SYSTEM, INCLUDING ALL DEVICES REQUIRED TO ACHIEVE THE SEQUENCES AND FUNCTIONS INDICATED

THROUGHOUT THE CONTRACT DOCUMENTS.

2. THE ATC CONTRACTOR SHALL FURNISH AND INSTALL ALL ELECTRICAL WIRING AND CONDUIT FROM

POWER SOURCE, INCLUDING TERMINATION TO ALL REQUIRED ATC RELATED POWER CONNECTIONS

INCLUDING, BUT NOT LIMITED TO, DDC CONTROLLERS (PROVIDE LOW VOLTAGE CONTROLLER FOR

AIR TERMINAL UNITS INCLUDING TRANSFORMERS AND DISCONNECT SWITCHES AS REQUIRED),

SENSORS, VALVE AND DAMPER ACTUATORS, AIR FLOW MONITORS, ATC PANELS, ETC. THE ATC

CONTRACTOR SHALL OBTAIN A SEPARATE ELECTRICAL PERMIT AS REQUIRED BY THE LOCAL

AUTHORITY. THE ATC CONTRACTOR SHALL BE WHOLLY RESPONSIBLE FOR ALL POWER

REQUIREMENTS NECESSARY FOR A COMPLETE INSTALLATION FROM THE POWER SOURCE TO ALL

ATC RELATED CONNECTIONS.

3. THE ATC CONTRACTOR SHALL COORDINATE AND VERIFY THAT ALL CONTROLLERS, DEVICES AND

ACCESSORIES ARE PROVIDED AS REQUIRED TO ACCOMPLISH ALL CONTROL FUNCTIONS AND

SEQUENCES INDICATED IN THE CONTRACT DOCUMENTS. WHERE CONTROL RELATED DEVICES ARE

NOT PROVIDED BY AN EQUIPMENT MANUFACTURER, IT SHALL BE THE RESPONSIBILITY OF THE ATC

CONTRACTOR TO PROVIDE THE CONTROL DEVICES REQUIRED TO ACCOMPLISH THE FUNCTIONS AND

SEQUENCES INDICATED.

4. THE ATC CONTRACTOR SHALL PROVIDE ALL CONTROLLERS, DEVICES, POINTS, ETC REQUIRED TO

ACCOMPLISH THE CONTROL SEQUENCES AND FUNCTIONS INDICATED ON THE DRAWINGS AND IN THE

SPECIFICATIONS. ALL POINTS SHALL BE TIED INTO THE BUILDING AUTOMATION SYSTEM (BAS). IN

ADDITION, THE ATC CONTRACTOR SHALL PROVIDE ALL CONTROLLERS, DEVICES, POINTS, ETC

REQUIRED TO CONTROL, OPERATE AND MONITOR ALL EQUIPMENT (IE. AIR HANDLING UNITS, AIR

VOLUME TERMINALS, FANS, VALVES, DAMPERS, ETC.) INDICATED THROUGHOUT THE CONTRACT

DOCUMENTS.

5. PROVIDE EQUIPMENT STATUS FOR ALL MECHANICAL EQUIPMENT. EQUIPMENT FAILURES SHALL BE

ALARMED AT THE BAS.

6. PROVIDE TEMPERATURE SENSORS TIED INTO THE BAS IN SUPPLY DUCTWORK DOWNSTREAM OF ALL

VAV TERMINALS.

7. GENERAL EXHAUST FANS SHALL BE PROVIDED WITH MOTOR OPERATED DAMPERS. UNLESS

OTHERWISE NOTED, DAMPERS SHALL OPEN WHEN FAN IS ENERGIZED AND CLOSED WHEN FAN IS

DE-ENERGIZED.

8. ALL AIR FLOW MONITORS (AFM) SHALL GENERATE AN ALARM CONDITION AT THE BAS WHENEVER

CONDITIONS EXCEED SETPOINT (ADJUSTABLE) BY 10% OR MORE.

9. WATER PRESSURE DROP THROUGH ATC CONTROL VALVES SHALL NOT EXCEED 10 FT. HEAD.

TWO-POSITION ATC VALVES UTILIZED FOR ISOLATION, BY-PASS OR SHUT-OFF PURPOSES SHALL BE

FULL LINE SIZE.

10. PROVIDE A TEMPERATURE SENSOR FOR ALL IT ROOMS AND ELECTRICAL ROOMS. MONITOR

TEMPERATURE AT THE BAS. SHOULD TEMPERATURE RISE ABOVE 90°F SETPOINT (ADJUSTABLE), ALARM AT THE BAS.

11. ALL SETPOINTS INDICATED ON THE SEQUENCES SHALL BE ADJUSTABLE.

12. ALL ATC WIRING SHALL BE INSTALLED IN CONDUIT.

1. ON A FALL IN TEMPERATURE, SPACE THERMOSTAT SHALL MODULATE

VAV TERMINAL DAMPER TOWARD MINIMUM SETTING.

2. ON A CONTINUED FALL IN TEMPERATURE, SPACE THERMOSTAT

SHALL MODULATE HEATING COIL VALVE TO MAINTAIN SETPOINT.

3. ON A RISE IN TEMPERATURE THE OPPOSITE SHALL OCCUR .

ENERGIZED AND OPERATRING. WHEN THE DRYER DE-ENERGIZES,

THE PRESSURE SWITCH WILL DE-ENERGIZE THE DRYER BOOSTER

FAN.

2. PRESSURE SENSING SWITCH SHALL BE FURNISSHED BY THE DRYER

BOOSTER FAN MANUFACTURER. INSTALLATION SHALL BE IN

ACCORDANCE WITH THE MANUFACTURER'S RECOMMENDATIONS

VAV AIR HANDLING UNIT CONTROL (WITH RA FAN)

1. GENERAL

1.1. SUPPLY AIR FAN AND EXHAUST AIR FAN OPERATION FOR EACH VENTILATION SYSTEM SHALL BE INTERLOCKED.

SUPPLY AND RETURN FANS SHALL OPERATE CONTINUOUSLY.

1.2. 30-AC-4 AND 30-ERU-2 ARE EXISTING AND OPERATE TOGETHER TO PROVIDE VENTILATION / EXHAUST AIR TO THE

FIRST FLOOR OF EXISTING NHCU ROOMS FOR "UNIT B" AND ARE LOCATED IN THE SECOND FLOOR MECHANICAL

ROOM.

1.3. RTU-1 IS EXISTING AND OPERATES CONTINUOUSLY TO PROVIDE VENTILATION / EXHAUST AIR TO THE SECOND

FLOOR OF THE EXISTING NHCU ROOMS FOR "UNIT B" AND IS LOCATED ON THE ROOF ABOVE THE SECOND FLOOR

MECHANICAL ROOM.

1.4. PROVIDE A HUMIDITY SENSOR IN THE EXHAUST AIR INLET OF 30-ERU-2 FOR CONTROL OF THE EXISTING

HUMIDIFIER LOCATED IN 30-AC-4. INTERLOCK WITH EXISTING HUMIDIFIER TO MAINTAIN A HUMIDITY SET POINT

(ADJUSTABLE). HUMIDITY SETPOINT SHALL BE ADJUSTABLE AND FROM ECMS

2. AIR FLOW / FAN CONTROL

2.1. OCCUPIED:

A. STATIC PRESSURE SENSOR, SPS-2, SHALL MODULATE THE SUPPLY FAN VARIABLE FREQUENCY DRIVE, VFD TO

MAINTAIN THE SUPPLY DUCT STATIC PRESSURE SETPOINT.

1) FAN PRESSURE OPTIMIZATION (STATIC PRESSURE RESET): EVERY 10 MINUTES (ADJUSTABLE) DURING THE

OCCUPIED MODE, THE DAMPER POSITIONS OF EACH VAV TERMINAL ASSOCIATED WITH THE AHU SHALL BE

POLLED. BASED ON FEEDBACK FROM THE VAV DAMPER POSITIONS, THE STATIC PRESSURE SETPOINT SHALL

BE RESET IN +/- 0.1" W.C. INCREMENTS (MAX 0.1" PER 10 MINUTE POLLING CYCLE) BETWEEN A FIXED RANGE

(LOW END SHALL BE MINIMUM 1.0" W.C. - ADJUSTABLE, UPPER END SHALL BE 0.25" W.C. ABOVE THE STATIC

PRESSURE SETPOINT DETERMINED BY THE BALANCE CONTRACTOR). IF THERE ARE NO VAV DAMPER

POSITIONS GREATER THAN 90% OPEN (ADJUSTABLE), THEN THE STATIC PRESSURE SET POINT SHALL BE

LOWERED UNTIL AT LEAST ONE VAV DAMPER IS AT LEAST 90% OPEN (ADJUSTABLE). IF ANY ONE VAV DAMPER

OPENS GREATER THAN 95% OPEN (ADJUSTABLE), THEN THE STATIC PRESSURE SET POINT SHALL BE RAISED

UNTIL THE MAXIMUM VAV DAMPER POSITION IS BELOW 95% OPEN (ADJUSTABLE). IF THE MAX. VAV DAMPER

POSITION IS BETWEEN 90% AND 95% OPEN (ADJUSTABLE), THEN THE STATIC PRESSURE SET POINT SHALL

REMAIN IN STEADY STATE UNTIL THE NEXT TEN MINUTE POLLING CYCLE.

B. AIR FLOW MONITORS LOCATED IN THE SUPPLY AND EXHAUST DUCTWORK SHALL MODULATE THE EXHAUST AIR

FAN VARIABLE FREQUENCY DRIVE, VFD, TO MAINTAIN AN AIR FLOW OFFSET EQUAL TO THE SUPPLY AIR FLOW.

C. HIGH LIMIT STATIC PRESSURE SENSOR, SPS-1 SHALL DE-ENERGIZE AHU FANS WHEN STATIC PRESSURE

REACHES 6.0" (ADJUSTABLE). ALARM AT THE BAS.
