B-8 ODORIZER, 1.5" NPT HOUSING AND GLASS CARTRIDGE
The odorizer assembly injects a scent into the carbon dioxide during a discharge to warn
personnel in the vicinity of the area protected by the fire suppression system that carbon
dioxide gas is present. The odorizer assembly consists of a protective housing and the odorizer
cartridge. This odorizer assembly was replaced by P/N 81-897600-000.
B-8.1 Odorizer Protective Housing
The protective housing, Part No. 81-897637-000 (Figure B-9), safely and securely attaches the
odorizer cartridge to the manifold. The stainless steel housing protects the odorizer cartridge
from inadvertent rupture.

B-8.2 Odorizer Cartridge
The odorizer cartridge, Part No. 10030080 (Figure B-10), is a 50cc glass vial filled with oil of
wintergreen, which provides the scent to the carbon dioxide. Upon discharge, the carbon
dioxide pressure ruptures the vial against the protective housing to release the oil of
wintergreen.
