433 MHz Receiver Installation Instructions

433 MHz Receiver Installation Instructions
Ultra-Small Receiver Installation
NOTE: Read this manual in its entirety before installing any Larco transmitter or receiver. It is important to complete the
programming procedure before installing the receiver in its final location. The installer must have access to the receiver’s
programming button and must be able to view the receiver’s LED (Light Emitting Diode) during the programming
process.
System
The Larco Ultra-Small Transmitters and Receivers operate at 433.92 MHz (acceptable in the United States, Canada and
any European Union member state) and employ code-hopping technology, to reduce false activations. The receiver only
operates after learning a transmitter’s signal through the simple procedure outlined on the next page. This programming
procedure eliminates the need to set dip switches and involves a simple press of the programming button located on the
top cover of the receiver (see drawings below for details).
Installation
NOTE: Complete the programming
procedure on the next page before
placing the receiver in its final
location.
1. Mount the receiver in a location
so that the antenna is not
surrounded by metal. Metal
attenuates RF signals causing a
reduction in range and
inconsistency of signal reception.
Door operator motors and
controls may also cause radio
frequency interference. Locate
the receiver away from the
door control’s motor(s) and
power supply(s). If the receiver is
mounted in a metal enclosure,
drill a hole in the enclosure and
thread as much of the antenna as
possible through the hole. This
reduces the effects the metal
enclosure will have on the
receiver’s reception.
2. The receiver comes equipped
with a wiring harness for easy
installation. Follow the colorcoding diagram at right.

Programming Procedures
NOTE: Prior to programming, make
sure the receiver’s LED blinks red
when power is applied. If the
receiver’s LED is not blinking red,
disconnect then reconnect the power.
Programming transmitter(s) into
the receiver’s memory:
The receiver can learn up to 12
transmitters. Follow the steps below
to program your receiver. Repeat
steps 1-3 for each transmitter.
1. Press the receiver’s programming
button for less than 2 seconds
and release. The LED should
change from blinking red to solid
green, indicating the receiver has
entered its programming mode.
2. Activate and release the
transmitter once and confirm
that the receiver’s LED changes
to solid red. This indicates the
receiver is learning the
transmitter’s code.
3. Wait a few seconds and then
activate the transmitter a second
time. The receiver’s LED should
now blink green several times
indicating that it is ending its
learning procedure. When the
procedure has ended, the LED
should be blinking red.
Programming the receiver’s
output activation time:
When the receiver is activated, its
outputs will stay in the minimum
activation state for approximately 1.5
seconds (default). This time can be
adjusted to stay in the activation state
for up to 4 hours. Follow the steps
below to adjust the receiver’s output
activation time.
1. Press the receiver’s programming
button for 4 seconds and release.
The LED should be solid red.
This indicates the receiver is in
the activation time programming
mode.
2. Activate and release the
transmitter.
3. When the desired time has
elapsed (up to 4 hours) activate
the transmitter again. The
receiver’s LED should blink
green several times indicating it is
ending the procedure. When the
procedure has ended, the LED
should be blinking red.
Deleting all transmitters from the
receiver’s memory:
You can clear the receiver’s memory
of all previously learned transmitters
by following the steps below. NOTE:
Deleting previously learned
transmitters does not change the
receiver’s output activation time.
1. Press the receiver’s programming
button for more than 8 seconds
until the receiver’s LED starts
blinking green. Release
the programming button. The
LED should now be blinking red.
2. The receiver’s memory is now
cleared. To learn new
transmitters, follow the steps for
programming transmitters into
the receiver’s memory.

The receiver and transmitter comply with FCC part 15/15.231-2001, Industry Canada RSS-210-2003, EN55022A-2000, EN55024-2001, EN300-220-3 V1.1.1-2000, and EN301-489-1
V1.2.1-2000. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any inerference received,
including interference that may cause undesired operation. This product may be susceptible to local transmissions being generated near the transmitter’s fundamental frequency.
Testing has shown some susceptibility in a frequency range of 416-440 MHz.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct
interference by one or more of the following measures: (a) Reorient or relocate the receiving antenna. (b) Increase the separation between the equipment and receiver. (c) Connect the
equipment into an outlet on a circuit different from that to which the receiver is connected (d) Consult the dealer or an experienced radio/TV technician for help.
The user is cautioned that any internal modifications, either replacement of or modification of any component, of the transmitter or receiver could violate the rules of compliance and
authority to operate the equipment.
