Use the illustration and instructions to understand
the system activity when you enable a DLA. Keep in
mind that an enabled DLA is only active when the
associated line is flowing water.
Note:
For instructional purposes, this illustration
only focuses on the specific activity in the
system that best conveys the topic.
1 The fire pump flows water into the discharge.
2 The enabled DLA measures the water flow in
the discharge.
3 The concentrate pump activates.
4 The magnetic flowmeter measures the amount
concentrate flowing in the DLA, while the valve
meters the concentrate proportioned into the
discharge to produce the selected solution.
5 The concentrate source is selected by the
concentrate-source valve. The valve switches
between an on-board or auxiliary concentrate
source. The valve position signal is provided to
the system—which uses this information to
determine when to monitor the on-board
concentrate level.
