Fire Suppression Systems for Low Voltage (LV) Electrical Rooms

An Low Voltage (LV) Room is a designated area or enclosure where the low voltage electrical equipment and components are housed. Low voltage typically refers to electrical systems with voltage levels below 1,000 volts AC (Alternating Current) or 1,500 volts DC (Direct Current).

LV rooms may contain electrical panels, switches, distribution boards, and other equipment used to distribute power within a building or facility.

These rooms are essential for safely managing and controlling the power supply to various devices and systems within a building.

Clean agent systems do not use water but use gases that don't leave residue after deployment. Gas Extinguishing systems are electrically nonconductive making them suitable for protecting sensitive equipment and electrical installations.

Inert Gas Extinguishing Systems

Inert gas fire systems once activated lower the oxygen level in the room to a point where the fire is extinguished but is safe for you.

A commonly used inert gas for electrical rooms is IG-55 (ArgoniteĀ®). IG-55 is an inert gas blend of argon and nitrogen, which occur naturally in the environment. With zero ozone depletion potential ODP, zero Global warming potential GWP and zero atmospheric lifetime, it has excellent environmental properties. A typical design concentration of 40% will reduce the oxygen level to 12.5% within 60 seconds.

Another gas is IG-541 (InergenĀ®). IG-541 is a mixture of 52% Nitrogen, 40% Argon and 8% CO2. However, in the event of a fire, when IG-541 is discharged, it mixes with the air present in the room to create a mixture that comprises of 67.3% Nitrogen, 12.5% Oxygen, 17% Argon and 3.2% Carbon Dioxide. As with IG-55, the mixture of gasses will reduce the oxygen levels down and extinguish the fire and will be safe for people within the room.
