4. When Alarm comes what we have to do first?
Identify Field or Building F&G Alarm?
At Fire Station
At Control Room
Check Building Fire
Monitoring Stations
Check Field F&G
Station Overview
Check Field F&G
Station Overview
Contact Fire Station for Building F&G
Identify the Area having Alarm
Silence the Alarm
Inspect the area find the abnormality
Do suitable action for rectification
Normalize the system by reset

5. Field F&G Alarms
Any of the Flame detectors, Point gas detectors, Open path detectors or Deluge valves operated will generate alarm.
Any manual call points if Glass is broken will generate alarm.
Any alarm generated will be highlighted on the operator screen and the corresponding zone will become red.

6. Field F&G Trips
Two no. of alarm generated in one Zone will be considered as a confirmed fire or gas presence in the zone and will result an alarm and process shutdown (PSD-2) for the particular zone.
Confirmed fire or gas alarm in two Zones will result in ESD1 and PAGA (Public address and general alarm system).
All the process and power except UPS power will trip.

9. Is Our Field F&G System Reliable?

10. Workout Done by F&G Team after commissioning
Cleaned and Serviced the detectors to avoid Frequent False alarm coming due to dust (by construction activity)
NRV installed in Deluge circuit to avoid False operation of other Deluge valves due to high DP across them
HVAC interlocks taken in line
Inergen system made ready (still in Manual)
Field F&G interlocks lined up
The Well pad Building F&G Alarm connected to our F&G CCB
Fire station HMI Installed for monitoring Field F&G
ESD- 1 taken in line with all relevant more than 35 F & G Tags which were in bypassed condition earlier
We have already reduced the AMC cost 50% by taking the building F&G PM jobs .

13. IR Flame Detector IR Flame Detector Make : Sharp eye Model no: 20/20SI
The principle of flame detector is based
on the detection of IR radiation from the
flame and Flame detector will gives Analog
output signal to the system. The system will
generate an alarm based on the intensity of IR rays

14. Open Path Gas Detector Detector Source
Open path Gas Detector OR Line of sight Gas Detector
Make : Spectrex Inc. – SafEye
Model : Source - OPS-FI3SE Model : Detector - OP-IF100SE
The principle of open path gas detector is based on the absorption of radiation ( IR rays ) caused by
the presence of Gases in the medium and the losses of the transmitted IR spectrum is sensed by the
Detector.
Detector
Source

15. Point Gas detector Point Gas detector Make : Crocown Model : Nimbus
Nimbus is a fixed point infrared gas detector for
the detection of common hydrocarbon gases in
the range 0-100% LEL and provides a 4-20 mA
signal proportional to the Gas concentration.

18. WORKING PRINCIPLE and OPERATION
Deluge valves are held shut with pressurized water placed
in the valve’s priming chamber. Release of water pressure by any of the below mentioned ways from priming chamber will operate deluge valve
If the Detection line pressure decreases due to QB rupture
Manual Operation from Field
Manual Command from DCS
Auto Operation Due to Confirmed Fire or Gas Alarm
