Vibration spring isolators for motor driven fans with electric motors 1/2 HP and greater and on associated piping and ductwork. .1 Seismic restraint of piping systems .2 Seismic restraint of duct systems .3 Seismic restraint of motor driven equipment .4 Seismic restraint of non-motor driven equipment 1 Installation of all controls hardware, wiring and programming of software as required for a completely operational, commissioned control and monitoring installation for the mechanical systems described herein. .2 The HVAC control system shall be based on Direct Digital Control, hard-wired, with electronic sensors and actuators. .3 The system, provided shall comply with the requirements of the latest version of ANSI/ASHRAE Standard 135 "Data Communication Protocol for Building Automation and Control Networks" .4 The existing system installed in the school is a Delta Controls System installed be ESC Automation. The upgrade will consist of expanding the existing controls system as required to accomplish the upgrade. .5 The Controls Contractor shall coordinate the requirements of all mechanical and electrical equipment to be controlled and be responsible for the coordination and interface requirements between the Controls, HVAC and Electrical Systems, as well as existing conditions. .6 All new DDC controllers are to be BTL listed. .7 All new electrical control components shall be CSA and ULC approved. .8 Utilize existing high speed internet connection for remote access. .9 The DDC system shall simultaneously accommodate more than one operator working on the system. .10 Provide complete dynamic color graphical user interface. .11 Wiring: .1 Provide all control wiring, whether line or low voltage, all system components, devices, actuators, relays, etc. as necessary for operation of the system. .2 Include for all wiring associated with the dust collector and devices, including explosion vent and blowback dampers. .3 Include for 24V wiring to automatic gates and current sensors at tools. .4 Include for all wiring controls requirement of dust extraction systems. .5 All wiring shall conform to the requirements of Division 16000 and the Canadian Electrical Code. .6 Control wiring to be a minimum of 18 gauge, run in conduit or as plenum rated cable where described below. .13 For existing sites undergoing upgrades, subject to prior approval by the Owner existing components maybe re-used such as relays, control panel enclosures, valves, damper actuators, temperature sensors, air proving switches, devices, components, wiring, conduit, etc., for line or low voltage interlocking. 14 For each motor program analog currents values to provide on/off/trouble indication. Fan currents are to be measured and recorded as a REMARK statement in the control coding for future reference in establishing the on/off/trouble indications. For fans that operate on low medium and high speeds the fan currents are to be measured and recorded as a REMARK statement in the control coding for future reference. These measured values will be used to establish on/off/trouble indications for operation at any of the selected speeds. System graphics are to visually indicate "ON", "Off", and "Status does not equal Command" for controlled equipment. .15 Commission the control system installed, including .1 VISUAL end-to-end checks on all actuated devices .2 Provide verification and calibration check sheets for all actuated devices for inclusion in the Operation and Maintenance manual. .3 Cooperate with the Testing, Adjusting and Balancing (TAB) agency for the following operations .1 Actuating of control valves and dampers to assist with air and water systems balancing .2 Provide access to programming and software code for review .3 Assist with random end-to-end checks for verification of controls operation .4 Provide remote access to the TAB agency for the duration of the warranty period. .16 Provide a minimum of 4-hours training and instruction to the Owner's maintenance personnel. .17 The Contractor is to include for three service visits during the warranty period. .18 Provide for inclusion of the Operation and Maintenance manual complete As- Built control drawings, sequences of operation, product data sheets for all newly installed products and end-to-end verification check sheets. Control drawings are to completely replace all existing control drawings for projects undergoing retrofit. .19 Provide and install point labels / baggage tags for all connected DDC points. The labeling standard Panduit LS9 Labeller or equal .20 The Controls Contractor is to coordinate all shutdowns and system switchovers with the Owner prior to the activity taking place. Allow 2 weeks' notice to allow adequate time for the Owner to coordinate the activity. .21 The Controls Contractor is to include supply of any required software licenses to allow the Owner to access and operate newly installed equipment.
