3. PROGRAMMING
3.1 Helpful Hints
A learning session is required to let the MCR-304 learn the ID
codes of individual wireless transmitters, which will all affect its
single relay output.
The quickest way to conduct a learning session is on the work
bench, with every transmitter you need within reach, and where
you may observe the receiver’s indicator LEDs.
3.2 Initial Steps
A.
Remove the screw that
secures the cover to the
base and remove the cover
as shown in Figure 3.
B.
Round up all transmitters to
be used in the system and
mark each one according to
the desired deployment plan.
Figure 3.
Cover Removal
It is advisable to use the “transmitter deployment table at the
end of this document.
C.
Temporarily power up the MCR-304 by connecting a 12 V
battery or a 12 VDC power supply across its
12 V
input
terminals (24 Volts AC or DC in case of MCR-304U).
Observe
polarity!
3.3 Selecting Memory Locations
The transmitter ID memory is divided into 10 locations, one per
each transmitter ID. Memory locations may be selected in
ascending order from 1 to 10, by clicking the MCR-304 tamper
switch.
The yellow LED indicates which memory location is selected. The
information is conveyed by flashing sequences as demonstrated
in the following chart:

3.4 Learning Transmitter IDs
A single transmission (control signal, Tamper or Restore) is
required to enroll a transmitter’s ID in the MCR-304 memory.
A specific transmitter’s ID may be enrolled in as many
locations as desired.
Note:
In case of PIR detectors, in which batteries are already
installed, cover the detector’s lens to prevent accidental
transmission during the learning session.
For “teaching” transmitter IDs, proceed as follows:
A.
Remove the MCR-304 cover.
B.
Set the OPERATE / LEARN jumper to
LEARN as shown at the right. The
yellow
LED will start flashing at a constant rate.
C.
Click the MCR-304 tamper switch the correct number of times
to select the desired memory location (see Para. 3.3.). Each
click advances to the next memory location. The red LED will
show the status of the selected location as follows:
Status
Red LED Response
Location is free
LED Flashes
Location already contains an ID
LED Lights steadily
To clear a “busy” location, refer to Para. 3.5.
D.
If the memory location is free, initiate a transmission from the
transmitter you wish to enroll in the selected location. Two
kinds of response may be expected:
Red LED Response
Significance
Lights steadily
Transmitter ID enrolled
Continues to flash
Transmitter ID not enrolled
Note:
You can not enroll a transmitter in a busy location.
E.
Repeat Steps B through D for all of the remaining transmitters.
G.
When done, 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 delete button located close to the jumper.
Notes:
(1) If the transmitter used is a wireless detector, remove its
battery to prevent accidental transmissions at a later stage of
the learning session.
(2)
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.
3.5 Clearing Transmitter IDs
A.
Set the OPERATE/LEARN jumper to LEARN. The
yellow
LED will start flashing at a constant rate.
B.
Click the MCR-304 tamper switch the correct number of times
(up to 10) to select the desired memory location (see Para.
3.3). The red LED 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 on the MCR-304 circuit board
once. The red LED 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.
3.6 What if the ID is Not Enrolled?
If the transmitted ID has not been accepted although the memory
location is free (the red LED continues to flash), try transmitting
again. If the second attempt is unsuccessful, the transmitter in
question may be faulty. Try enrolling another transmitter.
4. INSTALLATION
4.1 Selecting the Mounting Location
A.
The location selected for the MCR-304 must constitute a
compromise between maximum reception ability and
minimum distance from the control panel.
B.
Maintain the antenna vertical - tape it to the wall if required.
C.
Avoid installing the MCR-304 on or near large metallic objects
such as closets, circuit breaker cabinets, air conditioner ducts
and fine-mesh window screens.
D.
Do not locate the unit near dense electrical wiring.
