About this file
The provided document is a technical specification for the control system requirements of the supply fans SF-1-1 and SF-1-2 as part of the HVAC system in the Expand and Renovate Emergency Department B50 project at the Tucson VA Medical Center.
The key details include:
- The supply fans shall be started/stopped manually at the DDC through a bypass starter and operated at constant speed upon failure of the VFD.
- The system shall provide alarms for VFD faults, fan failure, and fan running in hand mode.
- The outside air damper shall open/close automatically with the fans, and alarms shall be provided for damper failure.
- The supply fan VFD speed shall be modulated to maintain a duct static pressure setpoint.
- The contractor shall be responsible for providing all necessary controls, sensors, and programming for a fully functional system.
This technical specification is part of the bid set documents for the federal contract opportunity 36c77623r0191 - "Y1DA--Expand and Renovate Emergency Department B50 Minor Construction - Tucson VAMC", issued by the Department of Veterans Affairs Technology Acquisition Center Austin.

EMERGENCY CONSTANT SPEED OPERATION
UPON FAILURE OF THE VFD, THE SUPPLY FANS SHALL BE STARTED/STOPPED MANUALLY AT THE
DDC THROUGH THE BY-PASS STARTER. FANS SHALL THEN BE OPERATED AT CONSTANT
SPEED.
AUTOMATIC SHUTDOWN/RESTART
WHEN SMOKE IS DETECTED BY EXISTING DUCT SMOKE DETECTOR, DSD, THE SUPPLY FANS
SHALL SHUT "OFF" AND AN ALARM SIGNAL SHALL BE TRANSMITTED TO THE FIRE ALARM
SYSTEM.
ALARMS
PROVIDE ALARMS FOR SUPPLY FAN VFD FAULT, SUPPLY FAN FAILURE (COMMANDED "ON" BUT
THE STATUS IS "OFF") AND SUPPLY FAN RUNNING IN HAND (COMMANDED "OFF" BUT THE
STATUS IS "ON").
SUPPLY AIR SMOKE DETECTION:
THE UNIT SHALL SHUT DOWN AND GENERATE AN ALARM UPON RECEIVING A SUPPLY AIR
SMOKE DETECTOR STATUS.

GENERAL
UNIT IS NORMALLY STARTED AND STOPPED REMOTELY AT THE DDC. H-O-A SWITCH SHALL BE KEPT IN THE "AUTO" POSITION. "HAND" AND "OFF" POSITIONS SHALL BE USED ONLY FOR MAINTENANCE.
RUN CONDITIONS - CONTINUOUS
THE UNIT SHALL RUN CONTINUOUSLY.
HIGH STATIC SHUTDOWN:
THE UNIT SHALL SHUT DOWN AND GENERATE AN ALARM UPON RECEIVING A HIGH STATIC SHUTDOWN
SIGNAL.
OUTSIDE AIR DAMPER
THE OUTSIDE AIR DAMPER SHALL OPEN ANYTIME THE UNIT RUNS AND SHALL CLOSE ANYTIME THE UNIT STOPS. THE SUPPLY FAN SHALL START ONLY AFTER THE DAMPER STATUS HAS PROVEN THE DAMPER IS OPEN. THE OUTSIDE AIR DAMPER SHALL CLOSE 5 SEC (ADJ.) AFTER THE SUPPLY FAN
STOPS.
ALARMS SHALL BE PROVIDED AS FOLLOWS:
• OUTSIDE AIR DAMPER FAILURE: COMMANDED OPEN, BUT THE STATUS IS CLOSED.
• OUTSIDE AIR DAMPER IN HAND: COMMANDED CLOSED, BUT THE STATUS IS OPEN.
SUPPLY AIR DUCT STATIC PRESSURE CONTROL:
THE CONTROLLER SHALL MEASURE DUCT STATIC PRESSURE AND SHALL MODULATE THE SUPPLY FAN VFD SPEED TO MAINTAIN A DUCT STATIC PRESSURE SETPOINT OF 1.0" W.C. (ADJ.). THE SUPPLY FAN
VFD SPEED SHALL NOT DROP BELOW 30% (ADJ.).
ALARMS SHALL BE PROVIDED AS FOLLOWS:
• HIGH SUPPLY AIR STATIC PRESSURE: IF THE SUPPLY AIR STATIC PRESSURE IS % (ADJ.)
GREATER THAN SETPOINT.
• LOW SUPPLY AIR STATIC PRESSURE: IF THE SUPPLY AIR STATIC PRESSURE IS % (ADJ.)
LESS THAN SETPOINT.
• SUPPLY FAN VFD FAULT.
DUCT STATIC PRESSURE
SENSOR 2/3 ON THE
LONGEST RUN.
NOTE TO TEMPERATURE CONTROL CONTRACTOR:
CONTROL CONTRACTOR SHALL BE RESPONSIBLE FOR
PROVIDING THE CORRECT TYPE, SIZES AND QUANTITIES OF
CONTROL CABLES, CONTROLLERS, SENSORS,
TRANSFORMERS, DEVICES AND PROGRAMMING
NECESSARY FOR A FULLY FUNCTIONAL SYSTEM.
