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.

11.3.9 CO
Fire Suppression System 
The enclosure can be equipped with a CO
2
 fire suppression system consisting of a 
primary total flooding distribution system and a secondary metered distribution system to 
extend the design concentration of 37% CO
2
 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 CO
fire suppression cylinder cabinets (Figure 23). On receipt of 
this signal, the solenoid actuated control heads activate the CO
2
 cylinders, releasing CO
into the enclosure. CO
2
 pressure actuates the pressure trip operated dampers that close 
all vent openings. CO
2
 release control heads are also provided with manual release 
levers. 
11.3.10 Water 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.
