FD Series - Automatic Fire Extinguishers, 500 ft³

The FD Series of pre-engineered/fixed fire extinguishers are factory rechargeable, and utilize FM-200 — a "clean" extinguishing agent.
FM-200 is a Halon replacement, and is safe for use around people and sensitive equipment, as well as in engine spaces.

Two models of FD extinguishers are available: automatic only (A models), and automatic with the option of manual discharge (M models).
These are the Automatic Only (A) models.

As "pre-engineered" systems, FD extinguishers are permanently mounted in a selected enclosed space - such as an engine room.
They are designed to produce a certain concentration of extinguishing agent (8.7%) in the volume specified on the extinguisher.
Full discharge occurs within 6 to 10 seconds for rapid extinguishment and minimal fire damage.
FD systems are suitable for use from 20°F (-7°C) to 130°F (54°C).
