 TM 55-1905-223-10
WARNING
The FM-200 system has been outfitted with a time delay override
located on top of the time delay.
When the time delay override lever is pulled, the 60 second time
delay is negated and FM-200 will immediately discharge into the
protected spaces.
This procedure should only be performed under extreme circum-
stances and with the authority of the watch officer or scene
commander.
Failure to observe these warnings could result in death or serious
injury.
Operate the WWS for a minimum of fifteen (15) minutes. During the WWS operating
period, approximately every three (3) minutes, open valve WWS-2, Tunnel WWS Strainer
Blow Off for approximately ten (10) seconds. This will allow foreign matter to be flushed
from the strainer basket.
WARNING
To reduce temperatures within the protected space and manage
the risk of HF exposure to humans, the WWS is designed and
intended to be operated for a minimum of 15 minutes. This
procedure should be followed to the full extent or death or
serious injury could occur.
NOTE
The tunnel FM-200 System is augmented with an installed WWS. If
necessary, the FM-200 System could be used as a stand alone system.
