To prevent possible SERIOUS INJURY or DEATH from
electrocution:
• Be sure power is not connected BEFORE installing the
receiver.
To prevent possible SERIOUS INJURY or DEATH from a moving
gate or garage door:
• ALWAYS keep remote controls out of reach of children.
NEVER permit children to operate, or play with remote
control transmitters.
• Activate gate or door ONLY when it can be seen clearly,
is properly adjusted, and there are no obstructions to
door travel.
• ALWAYS keep gate or garage door in sight until completely
closed. NEVER permit anyone to cross path of moving gate
or door.

SETTING THE SWITCHES
Before making changes to any of the DIP switches (Figure 1),
power MUST be disconnected from the receiver (unplug the
terminal block from J2 on the circuit board). Otherwise, your
changes will not take effect. Also, when setting the receiver’s DIP
switches, refer only to the numbers silk screened on the circuit
board (not the numbers on the DIP switch itself).
1. Disconnect power to the receiver.
2. Turn screws counterclockwise 1/4 turn and remove front
cover.
3. Before or while touching the circuit board, discharge any
static electricity:
(1) Use a grounding strap OR
(2) Touch a cold, grounded, metallic pipe.
4. The output code format switch settings are factory-set for the
30-bit format (Figure 2). To change the settings to 26-bit,
refer to Figure 3.
30-bit Switch Settings (Default):
S1, 3 = OFF or 0
S1, 2 = OFF or 0
S1, 1 = ON or 1
S1, 0 = ON or 1
26-bit Switch Settings:
S1, 3 = OFF or 0
S1, 2 = OFF or 0
S1, 1 = ON or 1
S1, 0 = OFF or 0
5. Set the transmitter button response(s).
• There are three DIP switches used to set the transmitter
button response(s) (Figures 4 or 5).
• To disallow receiver response to transmitter buttons, move
the DIP switch(es) to the LEFT. All button switches are
factory set to ON.
Switch S1, 1 controls Button #1 and Button #4*
Switch S1, 2 controls Button #2
Switch S1, 3 controls Button #3
* If using a CPT4 transmitter, Button #4 reacts to Button #1
settings, but uses a unique identification number and facility
code.
Left = OFF or 0
Right = ON or 1

SETTING THE SWITCHES CONTINUED
6. Set a Fixed Facility Code (FFC).
• The FFC switch must be in the ON position (switch set to
right).
• Set the receiver’s facility code switches (labeled 0-5) to match
the facility code of the access control system.
Refer to the switch settings chart in the Appendix on page 5 for
assistance.
NOTE:
For installations that require the facility code of the
transmitters to be passed to the access control system, set the
FFC switch to the OFF position (set switch to left). Facility codes
are set in the transmitter at the factory to avoid code duplication.

The outside of the antenna connector is not ground. If using
an extension kit, do not allow it to contact a metal object.
INSTALLATION AND WIRING
1. Mount the Receiver.
Mount receiver to surface using #6 hardware (not provided).
(Figure 8)
NOTE:
Mount receiver with 18" of space above the receiver for the
antenna. The receivers should be installed at least 5' apart to
avoid “cross-talk”.
2. Connect the antenna.
Screw on antenna clockwise and slide rubber boot down to
meet o-ring (Figure 7).
3. Connect signal/power wires.
Remove the terminal block from J2 on the circuit board.
Connect wires from the CPWR 6-pin connector to the access
control system (Figure 8). Then re-insert the terminal block
onto J2.
Wire the CPWR to the access control systems’ card reader
port. Refer to the access control system’s instructions for
appropriate wiring detail. A typical wire connection might
resemble the following:
NOTE:
At power up, the CPWR will perform a system check and
produce a series of LED flash sequences (this is normal).
Facility code switches 6-15 are not used (must remain in the
OFF or left position).
FFC Factory Setting = ON (switch set to right).
Facility Code Factory Setting = All OFF (switches set to left).

TESTING AND TROUBLESHOOTING
1. Check the power.
Ensure that the red POWER LED is lit (Figure 9). If not, check
your power connections and/or source. Voltage reading
should be within the range of 9VDC – 18VDC.
2. Check for Receiver operation.
The SIGNAL LED (Figure 9) should be flickering continuously,
indicating that the RF receiver circuitry is operating.
3. Test the Transmitter/Receiver.
Press the transmitter button previously set in step 4, page 3,
within view of the receiver. If the DATA-yellow and
VALID-green LEDs do not light, review the Setting the
Switches and Connect Signal/Power Wires sections.
NOTE:
If the DATA-yellow and VALID-green LEDs flash repeatedly
and simultaneously, the format settings may be incorrect (refer to
Output Code Format).
If reception of the transmitter’s signal is significantly reduced,
there may be strong RF interference from other sources.
Common sources of interference include fluorescent lights,
neon signs, mercury vapor lamps, arc welders, and arcing
power lines. Interference due to lighting can be limited by
having an electrician wire a noise suppressor into the lamp,
light, or sign circuit.
NOTE:
It may be required to press the transmitter button twice at
first use.
RECEIVER LED REFERENCE
(Figure 9)
SIGNAL – Red
This LED, when lit, indicates that the receiver has detected the
presence of RF energy. It is normal for this LED to flicker
continuously while the receiver is powered up.
DATA – Yellow
This LED indicates that the receiver recognizes the transmission
data as coming from a Chamberlain®transmitter with Passport
technology.
VALID – Green
This LED indicates that the receiver is sending a Wiegand format
output to the access control system.
POWER – Red
This LED indicates that the receiver has power.
GRANTED – Green
This LED indicates that the access control system has validated
the transmitted code and has granted access.
4. Attach the front cover.
Attach front cover of receiver by turning screws clockwise
1/4 turn. Do not over tighten.
Call your local power company if interference is due to arcing
power lines.
