Specifications include, but are not limited to: provided pressure monitoring services at the Texas Center for Infectious Disease (TCID). Contractor shall provide maintenance per manufacturer's specifications, of all Phoenix Control’s critical room controls installed in Building 502 at TCID. Equipment in each room includes exhaust valves in two sizes, 8 inches and 12 inches. Model MAVA112L is a 12-inch supply valve with a low-speed actuator. Model EXVA 108L is an 8-inch exhaust valve with a low-speed actuator. There are 141 rooms. Contractor shall provide critical airflow control system inspection per manufacturer’s specifications. Dynamic Zone Testing Control: The Contractor shall test each dynamic room condition (Infectious Patient Mode, Healthy Patient Mode, and Vacant Mode) once per year, using the room verification sheet and verify that the room’s designed pressurization is maintained throughout each operating sequence. Pressure independent controls shall maintain the scheduled (designed) infectious occupied flow rates at the exhaust valves. Exhaust flow rates shall be variable in order to maintain a 0.2 W.G. (water gauge) negative pressure with respect to the anteroom. The results will be verified electronically by the installed Critical Room Control (CRC-RM) room differential pressure sensor and tested against a shortridge transmitter for any required calibrations of the CRC-RM sensor. The results will be provided with the room verification sheets in a written report. This rotational basis will ensure that after a calendar year all pressurized zones will have been tested and verified for proper operation and control. All dynamic zone testing will require TCID to switch the various modes of operation from the Building Automation System (BAS) to ensure all aspects of monitoring and alarming are working as intended. The Contractor will verify that all differential room pressure alarms are verified at the BAS. Ante I Patient Room Airflow Verification: The Phoenix Controls field service technician will verify the proper balance of airflow for every lab at the time of service. To complete a room verification, the technician will: • Review the room schedule sheet and wiring diagrams to understand the application. • Use the proper verification table to document the test (The technician will create a unique table for this project). • Create the appropriate Modes of Operations and verify pressure control. • Verify the command and feedback signals at each Supply and General Exhaust. • Verify the minimum static pressure requirements across each air valve to be with in tolerance i.e., Medium Pressure valves 0.6" W.C. (inches of water column), Low Pressure valves 0.3” W.C. • Verify / Recalibration Room Differential Pressure sensors for each room. • Log the verified air flows in the room verification sheet in each of the modes of operation, per room: Infectious Mode Healthy Mode with no temperature override Healthy Mode with temperature override Vacant Mode • Log supply air temperature readings at the room diffusers to verify proper temperature control operation at the following modes of operation: Full Cooling Full Heating Integration Server Procedures: • To confirm information is being displayed properly on the front end, TCID will review the BAS as the contractor verifies each mode. • Any deficiencies will be noted in the contractor’s report for future follow-up if desired by TCID. • Contractor shall complete a full backup of each of the Phoenix integration servers.
