MCW-570
Automatic Flood Prevention System
Installation Instructions
1. INTRODUCTION
1.1 Purpose and Use
The MCW-570 is a fully supervised flood prevention system. It is triggered
by up to 10 flood detectors that are located inside the protected site
where presence of water flooding or leakage is probable.
Upon cold/hot water flood detection, the system automatically shuts off
the water supply to the protected site (by means of 1 or 2 cold/hot electro-
mechanical ball valves) and provides valve status indication, on the
Control Unit and on the water valve(s).
Turning ON the water supply, after repairing the water leak, is performed
by pressing the OPEN button - see figure 1.
Manual turning OFF the electro-mechanical ball valve is also possible, by
pressing the CLOSE button - see figure 1.
In case of power failure, it is possible, on some models, to manually
open/close the valve (see Fig. 8).
Optional - In addition to flood preventing, the system can also send ALARM,
TROUBLE and LOW BATTERY signals to a remote control unit for remote
indication (see figure 7).

1.2 Kit Contents
The MCW-570 system includes the following (see figure 1):
a. One Control Unit: In case of flood, the Control Unit receives signal
from up to 10 wireless water flood detectors, sends OFF command to
the water electro-mechanical valve(s) and provides indication of the
closed valve(s).
b. One wireless flood detector MCT-550: The flood detector transmits
an alarm signal to the Control Unit upon flood detection.
c. One cold water electro-mechanical ball valve: The electro-
mechanical ball valve is directly installed on pipe of central water
supply. The valve automatically turns OFF the water supply in case of
flood detection.
d. One power transformer - 9VAC output.
Note: The system is designed for use with water valves that are supplied
by the system manufacturer only.
1.3 LEDs Operation
The Control Unit includes 2 main LED indicators (see Fig. 1), that function
according to the following table:

The Control Unit includes 2 additional LED indicators (in the receiver module -
see Fig. 6), that are visible only after removal of the Control Unit cover:
•
Red SIGNAL / MEMORY STATUS LED - illuminates as long as the
receiver receives signal from recognized flood detector. This LED is
also used during the flood detectors “learning” process (described
in par. 3.3).
•
Yellow MEMORY LOCATION STATUS LED indicator - used during
the “learning” process.
