7.0  PROCEDURE

7.1   INSTALLATION OF FIRE FIGHTER SMOKE CONTROL STATION (FSCS) PANEL AND HAND OFF AUTO (HOA) MODULES

• For panel installations, check the location as per approved shop drawings.
  • Verify base frame dimensions, orientation and locations are correct.
  • For wall mounted (concealed, surface mounted) check the height and level as per approved shop drawings.
  • Check provisions for earthing and interface connections.
  • Check space/access are available for maintenance and future repair. Refer approved shop drawings.
  • After installing FSCS Panel, HOA Modules will be mounted to the front of the bay of the FSCS Panel and are properly fixed.
  • The LED/Switch Controller card will be installed onto the back of one of the display cards.
  • After the above installation, HOA Modules are connected using the Ribbon Cables.
  • LED Switch Controller will be connected to the FSCS Controller using 4 core Communication Cable.

• Visual Inspections
• Carry out a visual inspection from outside & inside of installed Smoke management system.
  • Visually check to ensure that all cards, switches, LEDs and customized mimic panel are installed in line with approved SMS drawings, Approved Material Submittal, Project Specification and in line with manufacturer’s recommendations & security standard and approved cause & effect matrix.

• Pre Commissioning Checks and Cold Testing
• Ensure the installation of the back box is proper.
• Ensure all cables are identified properly with cable markers.
• Ensure all switches and LEDs are installed towards the correct equipment and its labelling is properly done.
• Correct deficiencies if observed on pre-testing. Malfunctioning or damaged items shall be re-tested until satisfactory performance and conditions are achieved.
• Record results in  pre-commissioning check list

• Power up Check 24V DC and data cables.Check data & 24V DC cable polarity.Check data & 24V DC cable termination.Power up FSCS to energise SMS panel.

• Testing & Commissioning

Note: Prior to the testing of SMS, a notification has to be made through the Safety Engineer to all site people engaged in the plant rooms where Air Handling Units(AHU), Staircase Pressurization Fans (SPF), Laboratory Plume Fans (LEF), Lift Pressurization Fans (LPF) and Smoke Exhaust Fans (SMEF) are located to avoid any accidents as this test will switch on these fans immediately. Notices shall be pasted on the walls of these plant rooms. Also, the coordination and presence of the concerned suppliers is required for the test of all fans and dampers.

• Testing of Damper OPEN/CLOSE push buttons – OPEN/CLOSE push buttons are provided to manually OPEN or CLOSE the Supply Motorized Dampers and Return Motorized dampers. OPEN/CLOSE status LEDs are provided to show the actual status of these dampers. These push buttons can be tested in the following method:
  • Push the ON button down to manually OPEN any of the above mentioned dampers. (In normal condition, all the dampers will be closed. Hence all RED LEDs will be “ON” to indicate that dampers are closed.)  The Damper will get the 24V DC and it will start to open. When it is fully opened, the RED LED will change to GREEN LED to indicate that the damper is OPEN. Then push the “AUTO” Button to make all the dampers in AUTO Mode. Then to close the damper, Push the OFF Button so that the 24V will be cut off from the damper and all the dampers will be closed and all the green LED will go to RED after all dampers are closed. Then push the button “AUTO” to make all dampers in AUTO Mode. All dampers can be tested and confirmed in this way.
  • Testing of CLOSE/OPEN LED- These LEDs are provided to indicate the actual status of Supply Motorized dampers and Return Motorized dampers. Push the corresponding OPEN/CLOSE button to change the damper status and wait for the damper to operate. The LED status will change when the damper status changes to OPEN to CLOSE or vice versa.

• Testing of ON/OFF/AUTO switches – These are provided to manually turn ON the AHU, SPF, LPF, LEF and SMEF. These are 3 positioned switch and positions are printed on the panel. Flip up the corresponding switch to turn the fan ON and wait for the action to be taken. Status LED will glow to indicate the actual status of the MCC. Flip down to OFF and then to AUTO to make the fan bring back to AUTO position. Status LED also will change according to MCC status.
• Testing of ON/OFF/AUTO LEDs – These are to provide the MCC status of SPF, LPF, SMEF and CPF. Turn on the corresponding switch and wait for the fan to turn ON. LED status will change to ON from OFF & AUTO LEDs.

• LAMP test Switch – A switch is provided to test all LEDs. Press the LAMP TEST switch and make sure all LEDs are turned ON. Turn OFF the switch to turn OFF the test.

• Witness Demonstrations / Completion

After the successful commissioning the results will be recorded on the testing and commissioning sheets contained within section 8 of this document.
