System Operation
**************************************************************************
NOTE: For automatic operation include bracketed
phrase.
**************************************************************************
Flow of water and AFFF shall be controlled by deluge valves. Foam
proportioning equipment shall activate automatically upon tripping of the
deluge valve(s) for the corresponding foam system(s). Valves shall be
tripped by remote manual release stations [and by activation of the
detection system]. No valve will be operated by a building fire evacuation
alarm system. Use of motor-operated valves is prohibited. Once activated,
system(s) shall operate until shut down manually. Provide separate
circuits from the control panel to each zone of initiating devices.
Transmission of signals from more than one zone over a common circuit is
prohibited.
1.4.2.1
Tank System
Tank system shall be controlled by valves operated by remote manual release
stations [and by activation of the detection system].
[1.4.2.2
Monitor System
**************************************************************************
NOTE: Where monitors are activated solely by
manually opening a value (e.g. post indicator
valve), show valves on plans.
