Fire Suppression System
CO2 Fire Suppression System. Carbon dioxide (CO2) is a proven fire fighting agent which has been in
use for many years. The “fire triangle” has three components: fuel, oxygen, and an ignition source. Any
fire suppression system must control one of these three components in order to be successful. Carbon
dioxide works well on all fires because it displaces oxygen, thereby breaking one leg of the fire triangle. It
is an effective fire fighting agent in tightly enclosed areas, leaves no residue, and is safe for electrical
systems.
Since CO2 does not significantly reduce the temperature of the burning material, concentrations of CO2
must be sufficient to displace oxygen until the temperature of the burning materials drops below their
ignition temperature; otherwise, the fire may flash back. To work effectively, the carbon dioxide must
bereleased into an enclosed space; therefore, openings on an equipment enclosure can significantly
reduce its effectiveness.
Accordingly, the enclosure is 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 twenty (20) minutes.
On detection of fire, the detectors transmit an electrical signal via the fire control panel to activate the fire
suppression system release solenoids located on the fire suppression skid. On receipt of this signal, the
solenoid actuated control heads activate the discharge valves on the primary and extended extinguishing
cylinders, releasing the extinguishing agent 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.
Solar’s scope of supply will include either a CO2 Fire Suppressant Cylinder Rack, or a CO2 Fire
Suppressant Cylinder Cabinet, as further defined below. In each case, they include the following
features:
100 lb CO2 bottles
“fill status” indicator
“single pull” manual activation
externally mounted junction box for simplified wiring
