MCR-304
Wireless Interface for Hard-Wire Control Panels
1. INTRODUCTION
1.1 Purpose and Use
The MCR-304 is a single output wireless
PowerCode / CodeSecure™ receiver designed
to add fully supervised wireless capabilities to
hard-wired control panels, as demonstrated in
Figure 1.
The MCR-304 can be connected to various
control panels for remote control purposes and
can use up to 10 Powercode / CodeSecure™
wireless devices for remote control.
The MCR-304 will recognize only those
devices with IDs that have been “taught” into its
non-volatile memory. Other devices will be
ignored.
Detailed teaching/learning procedures are provided in
Paragraphs 3.4 and 3.5.
The MCR-304 provides trouble, low battery and tamper outputs
which are common to all 10 wireless devices.
1.2 Control Output
The MCR-304 features a single FORM-1C relay output that
reacts to control signals received from up to 10 wireless detectors
or hand-held transmitters. The relay can be programmed to
operate in the Pulse or Toggle modes (see Para. 4.4 for full
details).

1.3 Status Outputs
In addition to the single relay output, the MCR-304 provides 3 opencollector status outputs that function as follows:
Tamper: This output is activated once a TAMPER state is
detected in a transmitter or in the MCR-304 receiver itself.
Low Battery: This output is activated whenever a low battery
message is received from one of the detectors/transmitters.
Replacing the battery in the transmitter that sent the low-battery
message and transmitting once again resets the output.
Trouble: This output is activated if a supervised transmitter fails
to send its attendance message within a 4-8 hours time frame.
1.4 Construction Details
For construction details, refer to Figure 2.
1.5 Receiver Operating Modes
Two operating modes are available:
OPERATE - normal position (receiver stands by for signals)
LEARN - enrollment of transmitter IDs in the MCR-304
memory.
1.6 LED Functions during Operation
SIGNAL indicator (red - visible through a hole in the cover):
This LED illuminates when the output relay is energized and
continues to light for as long as the relay remains energized. The
LED extinguishes when the relay drops out.
Note: The red LED has a different function during the learning
session (see Paragraphs 3.4 and 3.5).
Memory Location indicator (yellow - visible only when the
cover is removed): This LED is extinguished in normal operation,
but has a special function during the “learning” session.

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.
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:
No. of

One 1st
Two 2nd
Three 3rd
Four 4th
Five 5th

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
Location already contains an ID
LED Flashes
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
Continues to flash
Transmitter ID enrolled
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
Continues to light steadily
Success (ID deleted)
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.
