3. FLOOD DETECTORS ENROLLING IN THE CONTROL UNIT MEMORY
Note: The system is supplied with 1 flood detector whose enrolling
process was already performed by the manufacturer. If the system will
include 1 flood detector only, proceed to chapter 4. If more detectors will
be used, proceed to paragraph 3.1 to "teach" the system to identify the
additional detectors.
3.1 Helpful Tips
A learning session is required to let the Control Unit learn the ID codes of
individual wireless flood detectors that will control the electro-mechanical
water valve.
The quickest way to conduct a learning session is on the work bench,
where every required flood detector is within reach, and where you may
observe the Control Unit indication LEDs.
3.2 Initial Steps
A. Remove Control Unit cover (see figure 5 steps 1 & 2).
B. Temporarily power up the Control Unit by using the supplied 9VAC
adapter.
C. Open the flood detector and insert battery (see figure 3).
3.3 Learning Flood Detector IDs
A single transmission (Flood alarm, Tamper or Restore) is required
to enroll a flood detector’s ID in the Control Unit memory.
For “teaching” flood detector IDs into the receiver memory, proceed as
follows:
A. Set the OPERATE / LEARN jumper (see Fig. 6) to
LEARN as shown at the right. The yellow LED (see
Fig. 6) will start flashing at a constant rate.
Description of Yellow LED (Memory Location) Indications
The flood detectors identification, in the receiver module memory, is
divided into 10 locations, one per each flood detector ID. Memory
locations may be selected in ascending order from 1 to 10, by clicking the
receiver module tamper switch (see Fig. 6).
The yellow LED (see figure 6) indicates which memory location is
selected. The information is conveyed by flashing sequences as
demonstrated in the following chart:

B. Click the receiver tamper switch (see figure 6) the correct number of
times (1 - 10) to select the desired memory location. Each click of the
tamper switch advances to the next memory location according to the
above table. The SIGNAL / MEMORY STATUS LED (red, see Fig. 6)
will show the status of the selected location as follows:
Memory Status
Red LED Response
Location is free
LED Flashes
Location already contains an ID
LED Lights steadily
C. If the memory status is free (as shown in the above table) initiate a
transmission from the flood detector you wish to enroll in the selected
location, by inserting battery into the flood detector or (if it's battery
was already inserted) click the flood detector tamper switch (see
figure 6).
Two kinds of response may be expected:
Red LED Response (Fig. 6)
Significance
Lights steadily
flood detector ID enrolled
Continues to flash
flood detector ID not enrolled
Note: You can not enroll a flood detector in a busy location.
D. Repeat Steps B through C for all of the remaining flood detectors.
E. Caution: During the next action be careful not to touch the DELETE
button, otherwise the flood detector enrolling may be erased!
Quit the LEARN mode by setting the OPERATE /
LEARN jumper back to OPERATE, as shown at the
right.
CAUTION! While handling the jumper, take care not to touch the
TOGGLE/PULSE jumper and DELETE button located close to the
jumper. Verify that the TOGGLE/PULSE jumper is in PULSE position!
Note
If you leave the jumper in the LEARN position and no further learning
activity takes place for 5 minutes, the LEARN mode will be
automatically
abandoned.
3.4 Clearing Flood Detector IDs
A. Set the OPERATE/LEARN jumper to LEARN position. The internal yellow
LED (see Fig. 6) will start flashing at a constant rate.
B. Click the receiver tamper switch (see Fig. 6) the correct number of
times (up to 10) to select the desired memory location (see Para. 3.3).
The red LED (see Fig. 6) will show the status of the selected location
as follows:
Status
Red LED Response
Memory location is free
LED Flashes
Memory location already contains an ID
LED lights steadily
C. Click the DELETE pushbutton (see Fig. 6) once. The red LED (see Fig.
6) will respond as follows:
Red LED Response
Significance
Flashes at a constant rate
Success (ID deleted)
Continues to light steadily
Failure
D. When done, quit the LEARN mode by setting the OPERATE/ LEARN
jumper back to OPERATE.
3.5 What if the ID is Not Enrolled?
If the flood detector ID has not been accepted even though the memory
location is free (the red LED continues to flash), try transmitting again. If
the second attempt is unsuccessful, the flood detector in question may be
faulty. Try enrolling another flood detector.
4. FLOOD DETECTOR AND FLOOD SENSOR INSTALLATION
4.1 Flood Sensor Installation
a. locate the flood sensor on the wall, near the floor, according to the
required height. The recommended height is 0-3 cm from the floor.
b. Fasten the sensors' cable to the wall with 3 clamps. The first clamp
should be very close to the sensor and the other 2 clamps as desired.
Note: To protect the cable from rats, it is recommended that the cable will
be inside a plastic/iron tube.
4.2 MCT-550 Flood Detector Installation
The detector must be installed vertically (see figure 2) and fastened to the
wall as high as possible, to improve the radio communication and prevent
contact with water in case of flood. The installation process is shown in
figure 3. Countersunk head screws should be used to prevent short circuit
in printed circuit.
