The first step is to check whether all the RFIs are closed and comments has given. All major comments to be closed. Complete the pre-commissioning check list and verify all the components has installed as per approved installation drawings. Verify the programming has done properly. If it is an addressable system it can be auto programed or manual. Check all the components (all loops) has been detected by the main fire alarm panel. If any part is missing, need to recheck the continuity of the loop, terminations and working condition of missing units.

Important - Until commissioning the fire alarm and detection system, the fire protection system should not be armed. Fire water pumps should be on bypass. Close the main discharge valve and let to operate the release valve.

1. Bridge terminals of the manual alarm call point. The alarm system should be activated.

2. Activate heat and smoke detector individually. The appropriate alarm should start. If the area protect by FM-200, when start the first alarm press and hold the Abort switch. The release valve (Trigger) of the bottle should not activate. Then release the Abort switch. The valve should activate. Repeat the test but do not touch the Abort switch. After few seconds of first alarm the second alarm should start. After few seconds of second alarm the system should activate. Monitor the time intervals and compare with standards. Reset if needed.

3. Bridge terminals of manual release call point (for FM-200 and Foam systems individually). The release valve should be operated. While the release valve of the Foam release in open position, press the Abort push button. The valve should be closed.

As mentioned above activate the gas and flame detector and monitor the system operation. At the mean time check the indications on fire alarm panel, annunciators /notifiers and release panels too. Further, check the condition of the battery backup units and rectifiers.

This is a quite long process. I think this will helpful to get an idea.
