Make sure the devices are fitted correctly.

Make sure the devices fixing height as per the requirement.

Make sure the control panel location as per the approved drawing.

Check the cable dressing and ferrule at the panel to identify the loop/sounder circuits.

Check and confirm the correct cables are terminated at the required terminals in the control panel.

Check and confirm the integration with other systems.

Testing and Commissioning Process-

Commissioning procedure

The respective software/logic will be downloaded to the panels.

The functioning of the control logic for all the equipment connected to the system will be checked as per the approved sequence of operation or cause & effect matrix and corresponding functional test plan for that equipment.

All field devices will be complete and submitted by the main contractor along with a work inspection request to witness the test.

Interface Requirements

Control of any interfaced equipment will be tested in presence of the responsible person for the equipment.

The termination of cables by the main contractor between the interface unit and the system will be as per the recommendation by the system supplier.

Any wiring diagrams applicable for such interfaces will be made available during the installation stage.

Testing & commissioning to be carried out as per the attached test report

The testing and commissioning shall be done in the presence of the owner’s representative and shall fully convince that the test results are satisfactorily carried out.

Test report for field devices, such as heat detector, smoke detector, manual pull stations, monitoring module, and control module.

The functionality will be checked with alarm response time, interface condition, etc. Test report for the panel to check the led status and manual/automatic operations.

Cable Testing

Cable testing will be carried out as per the attached sheet. The test has been carried as follows:

  • Identify the cable loop number, connecting to the devices (address), and location of the cable that needs to be tested.
  • One end of the cable (Positive, negative & Earth) has to be kept open and test the cable resistance value in the other end. This insulation test value should be more than 1 megaohm.
  • Make a short circuit in one end of all cables (Positive, negative & Earth). Test the cable resistive value in the other end.
  • This shows the continuity test value near zero ohms.
  • These tests show the circuit reference number, location between the devices, insulation tests, and continuity tests.
  • Normally this shows the cable should not be any open or short circuit between the wires.
