433 MHz Receiver & Transmitter

Installation Instructions

System

The Larco ultra-small receiver and transmitters 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

aer 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 Diagram 1).

NOTE: Read this document 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.

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 and power

supply. 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.

The receiver comes equipped with a wiring harness for easy installation.

Reference the wiring diagram (see Diagram 2) for proper connections.

Installation

Complete the programming procedure before placing the receiver in ﬁnal location.

The receiver and transmitter comply with FCC part 15/15.231, Industry Canada RSS-210,

EN55022A, EN55024, EN300-220-3, and EN301-489-1. 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.
