• All applicable test equipments / test gases, recommended by the vendor (s), must be made available.

• Prior to starting the FaG caE tests, all detectors and associated alarms / indications on the remote FCS HMI Mimic panel must have been tested as part of the instruments loop checks (Effects)_

Test Sequence

The testing is in 2 steps.

• Testing of individual detectors against low level and high level alarms and their respective effects.

• Testing of the voting logic (2 out of the total number of detectors in a zone / process area) and verifying the effects_

Testing of Individual detectors and voting logic

Testing of individual detectors and the voting logic verification will be in accordance with the Cause and Effects matrix_ The following active alarms will be used to verify the plant shutdown as part of the ESD Cause and Effects tests:

• Confirmed flammable gas detection

• Confi rmed toxic gas detection

• Confirmed heat and flame detectjpn

• Confirmed smoke detection

• Break glass unit detection

Confirmed Flammable Gas Detection

Individual Flammable gas detectors in all zones will be tested by applying test gas to generate low level and high level flammable gas alarm indications and check the effects as per the CaE charts_

The low level alarm settings are as follows:

• 20% LEL of methane in air for the process areas

• 10% LEL of methane in air for HVAC air intakes at battery rooms, LER and substation

• 15% LEL for ventilation and combustion air intakes at EDG and Hot Oil Heater

The high level alarm settings are as follows:

• 50% LEL of methane in air for the process areas

• 20% LEL of methane in air for HVAC air intakes at battery rooms, LER and substation

• 25% LEL for ventilation and combustion air intakes at EDG and Hot Oil Heater

Finally, the voting logic will be tested by applying test gas (60% LEL) to any 2 out of the total numbers of flammable gas detectors (zone wise) to generate a confirmed gas detection and the effects will be checked as per the CaE charts.
