Turbomachinery Package Specification	Titan 250 Generator Set

The enclosure is also equipped with two gas detectors: one at the gas turbine enclosure ventilation air inlet and the other at the ventilation exhaust to provide continuous monitoring of combustible gases. The detectors consist of IR hydrocarbon sensors that provide input to the logical operating network (LON) module. The gas turbine start signal is interlocked with the combustible gas monitoring system to ensure the atmosphere is safe prior to initiating a turbine engine start. An alarm is initiated if the gas monitor fails.

Figure 22. Typical Fire and Gas System11.3.9CO2 Fire Suppression System

The enclosure can be equipped with a CO2 fire suppression system consisting of a primary total flooding distribution system and a secondary metered distribution system to extend the design concentration of 37% CO2 for 20 minutes.

On fire detection by the optional fire and gas detection system, the detectors transmit an electrical signal via the fire control panel to activate the fire suppression system release

solenoids located in the CO2 fire suppression cylinder cabinets (Figure 23). On receipt of this signal, the solenoid actuated control heads activate the CO2 cylinders, releasing CO2 into the enclosure. CO2 pressure actuates the pressure trip operated dampers that close all vent openings. CO2 release control heads are also provided with manual release levers.

11.3.10Water Mist Fire Suppression System

The enclosure can be equipped with a water mist (fine water spray) fire suppression system consisting of a high-pressure distribution system to provide approximately 10 minutes continuous water discharge. The typical water mist fire suppression cylinder cabinet (Figure 24) consists of two high-pressure nitrogen cylinders used as a propellant and five water bottles.
