A. EXHAUST FAN OPERATING AND SAFETY CONTROLS SHALL INCLUDE:

1. WALL MOUNTED DISCONNECT

2. VARIABLE FREQUENCY MOTOR DRIVE

3. FAN DIFFERENTIAL PRESSURE SENSOR

4. BYPASS DAMPER AND DAMPER ACTUATOR

B. THE EXHAUST FANS SHALL OPERATE AT ALL TIMES ON A LEAD / LAG BASIS.

C. THE CONTROL SYSTEM SHALL ROTATE LEAD / LAG FANS ON A WEEKLY BASIS TO MAINTAIN EQUAL RUN TIMES ON BOTH FANS.

THE CHANGE OVER SHALL OCCUR AT 2:00 AM ON FOLLOWING DAY. COORDINATE WITH COR FOR TESTING SCHEDULE.

D. UPON FAILURE OF THE LEAD FAN AS DETERMINED BY THE MOTOR CURRENT TRANSDUCER BEING OFF SETPOINT THE CONTROL SYSTEM SHALL START THE LAG FAN, DISABLE THE WEEKLY LEAD / LAG CHANGE OVER AND SHALL ALARM THE

CONTROL SYSTEM USER INTERFACE.

E. FOR EF-01, MD-01 WILL BE NORMALLY OPEN. FOR EF-02, MD-02 WILL BE NORMALLY CLOSED. UPON FAILURE OF EF-01, MD-01

WILL CLOSE. MD-02 WILL OPEN AND EF-02 WILL ACTIVATE.

F. THE CONTROL SYSTEM SHALL MODULATE THE FAN BYPASS DAMPER TO MAINTAIN EXHAUST DUCT STATIC PRESSURE AT

SETPOINT AND FAN CFM CONSTANT.

G. THE STATIC PRESSURE SETPOINTS SHALL BE DETERMINED BY THE TAB CONTRACTOR DURING TAB WORK.

H. FANS SHALL RUN AN ADDITIONAL 30 SECONDS AFTER THE GENERATORS STOP RUNNING TO CLEAR EXCESS EXHAUST

WITHING THE DUCTWORK.

I. ALARMS: THE CONTROL SYSTEM SHALL ALARM THE USER INTERFACE AND TAKE INDICATED ACTION WHENEVER ANY OF THE

FOLLOWING CONDITIONS OCCURS:

1. MOTOR CURRENT PLUS OR MINUS 10% OF FULL LOAD AMPS FOR 10 SECONDS OR LONGER. STOP LEAD FAN AND TURN ON LAG FAN AND SUSPEND WEEKLY LEAD / LAG SWITCH OVER. FULL LOAD CURRENT SHALL BE AS DETERMINED DURING

TEST AND BALANCE.

2. NO AIR FLOW FOR 5 SECONDS OR LONGER. STOP LEAD FAN AND TURN ON LAG FAN AND SUSPEND WEEKLY LEAD / LAG

SWITCH OVER.

3. EXHAUST PRESSURE NOT AT SETPOINT FOR 30 SECONDS OR LONGER. STOP LEAD FAN AND TURN ON LAG FAN. SUSPEND

WEEKLY LEAD / LAG SWITCH OVER.

4. WHEN THE EXHAUST FAN IS OPERATING IN MANUAL OVERRIDE AS DETERMINED BY FAN OPERATION OUTSIDE THE CONTROL OF THE CONTROL SYSTEM. THE ALARM SHALL TOTALIZE THE MINUTES OF MANUAL OVERRIDE OPERATION.

VA STATION CONTROL NOTES, LEGEND,

CONTROL SCHEMATIC, SEQUENCE OF

CONTROL, AND CONTROL POINT

M800

1. CONTRACTOR SHALL PROVIDE COMPLETE DDC AUTOMATIC TEMPERATURE CONTROL SYSTEM COMPATIBLE

WITH THE EXISTING SYSTEM.

2. THE EXISTING CONTROLS SYSTEM IS SEIMENS INSIGHT WITH P2 NETWORK CONTROLS. THE CONTRACTOR SHALL PROVIDE NEW DDC CONTROLS THAT SHALL BE CONNECTED TO THE EXISTING SYSTEM AND BE INCORPORATED INTO THE EXISTING USER INTERFACE (UI). THE FINAL PRODUCT SHALL BE A COMPLETE, FUNCTIONING SYSTEM THAT IS FULLY INTEGRATED.

3. THE CONTRACTOR SHALL INCLUDE GRAPHICS IN THE EXISTING UI FOR ALL NEW SYSTEMS AND MODIFY ANY

AND ALL EXISTING GRAPHICS TO ACCURATELY DEPICT THE NEW WORK AND FUNCTIONALITY.

4. THE CONTRACTOR SHALL INTEGRATE THE CONTROLS SO THAT ALL NEW CONTROL POINTS CAN BE FULLY

OVERRIDDEN BY THE EXISTING DDC SYSTEM THROUGH THE UI.

5. THE EXISTING DDC CONTROL UI SHALL PROVIDE HIGH AND LOW ALARMS AS APPLICABLE FOR ALL INDICATED

CONTROL INPUTS.

6. THE NEW GENERATOR EXHAUST FANS UTILIZES A LEAD/LAG OPERATING SCHEDULE AND SHALL ALTERNATE ON

A WEEKLY BASIS AFTER EACH TESTING. COORDINATE WITH COR FOR TESTING SCHEDULE.

7. CHANGE-OVER SHALL ALSO TAKE PLACE AT 2:00 AM AFTER RUN-TIME DIFFERENCE EXCEEDS 8 HOURS

(ADJUSTABLE). MANUAL CHANGE-OVER CAPABILITY SHALL BE INCLUDED.

8. CONTRACTOR SHALL COORDINATE LEAD/LAG OPERATING SCHEDULE AND PROGRAM WITH COR BEFORE WORK

BEGINS.

1 EXHAUST FAN

1. CONTRACTOR SHALL INSTALL EXHAUST FANS (EF-01 AND EF-02) ONTO ROOF AS SHOWN IN THE DRAWINGS (1/M101). CONTRACTOR SHALL INSTALL ALL

DUCTWORK AND MECHANICAL DAMPERS ON ROOF TOP ONLY.

2. CONTRACTOR SHALL COMPLETE THE DUCT CONSTRUCTION ON THE ROOF TOP AS SHOWN IN THE DRAWINGS 1/M101. CONTRACTOR SHALL ENSURE THE FAN IS POWERED, DDC PROGRAMMED, TESTED, AND CONFIRMED TO BE WORKING BEFORE MOVING OFF THE ROOF.

3. AFTER ALL THE ROOFTOP CONSTRUCTION IS COMPLETED, CONTRACTOR SHALL BEGIN TO CONSTRUCT THE DUCT SYSTEM TOWARDS THE EXHAUST PIPES AS SHOWN IN DRAWINGS (2/M101). DO NOT PLACE THE MANIFORLD OR DUCTS OVER THE EXHAUST PIPES ON THE BOTTOM LEVEL.

4. CONTRACTOR SHALL ENSURE THAT ALL THE DUCTING SYSTEM BEYOND THE MANIFOLD IS CONNECTED AND READY TO HAVE THE MANIFOLD AND

SNAPLOCK DUCTS TO BE ATTACHED TO THE DUCTING SYSTEM.

5. CONTRACTOR SHALL BEGIN THE CONSTRUCTION OF THE MANIFOLD AND SNAPLOCK DUCTS. THE SNAPLOCK DUCTS WILL GO OVER THE EXHAUST PIPES PENETRATING FROM THE WALL. DO NOT PLACE THE MANIFOLD OR ANY SNAPLOCK DUCTS. ENSURE BOTH EF-01 AND EF-02 ARE COMMISSIONED AND

FULLY OPERATIONAL BEFORE MOVING ON TO STEP 6.

6. AFTER CONSTRUCTION OF THE MANIFOLD AND SNAPLOCK DUCTS ARE COMPLETED, CONTRACTOR WILL ATTACH THE SNAPLOCK DUCTS OVER THE EXHAUST PIPES FIRST, FOLLOWED BY THE MANIFOLD SECOND. THE MANIFOLD WILL NEED TO BE CONNECTED TO THE 3 SNAPLOCK DUCTS AND THE

DUCTING SYSTEM RUNNING DOWN FROM THE ROOF.

7. AFTER THE CONNECTIONS ARE COMPLETED, 1 OF THE 3 GENERATORS WILL NEED TO BE TAKEN OFFLINE. CONTRACTOR SHALL COORDINATE WITH THE COR ATLEAST 4 WEEKS IN ADVANCE. THE SNAPLOCK DUCT ON THE EXHAUST PIPE FROM THE GENERATOR THAT IS OFFLINE, WILL NEED TO HAVE THE SNAPLOCK DUCT REMOVED. A STAINLESS STEEL DUCT WILL BE PLACED OVER THE EXHAUST PIPE AND WELDED. AFTER THE WELDED STAINLESS STEEL DUCT IS ATTACHED TO EXHAUST PIPE, THE WELDED DUCT WILL NEED TO BE ATTACHED TO THE MANIFOLD.

8. CONTRACTOR SHALL ENSURE THAT THERE ARE NO LEAKS IN THE ENTIRE DUCT SYSTEM, THEN BRING THE GENERATOR THAT IS OFFLINE BACK ONLINE.

9. CONTRACTOR SHALL REPEAT STEPS 7 AND 8 UNTIL ALL 3 EXHAUST PIPES HAVE WELDED STAINLESS STEEL DUCT AND ARE ATTACHED TO THE

MANIFOLD. ENSURE NO LEAKS ARE FOUND WITHIN THE DUCT SYSTEM AS FINAL CHECK.
