PRICE $25.00

The Sentry 300 030212 LCR transmitter is a 4-button visor remote for compatible USAutomatic and Sentry 300 433.92 MHz LCR fixed-code receiver systems. It is useful when one remote needs to control more than one compatible receiver, such as a driveway gate, additional gate, garage receiver, or other wired access function. Each button must be matched to a compatible receiver and set up according to the system wiring and programming method. This remote belongs to the LCR dip-switch style transmitter family with 19,683 possible code combinations. It is commonly associated with Sentry 300 operators and select USAutomatic Patriot or Ranger installations that still use the LCR receiver platform. It is not a universal remote for every USAutomatic system, so frequency and receiver style should be confirmed before purchase.

Description

Sentry 300 030212 LCR 4-Button Remote Overview

The Sentry 300 030212 is the 4-button version of the USAutomatic LCR transmitter family. It is commonly used when a customer wants one handheld or visor-mounted transmitter to operate multiple compatible LCR receivers. Typical uses include Sentry 300 swing gate control, a second compatible gate receiver, a garage receiver, or another access-control input where the receiver has been wired for that function.

This is a 433.92 MHz fixed-code transmitter. It should be matched to the receiver technology, not just the Sentry or USAutomatic brand name. Older LCR systems, high-security receiver systems, and aftermarket receiver conversions can look similar from the outside but require different transmitters.

Technician Note

Use the 4-button remote when the installation actually has multiple compatible receiver inputs. If the system only uses one receiver channel, the extra buttons will not create extra functions by themselves.

Before Ordering Checklist

Confirm the receiver is a 433.92 MHz USAutomatic LCR fixed-code receiver.
Decide whether the customer needs four buttons or if the 030210 2-button remote is enough.
Match each button to the intended compatible receiver or channel.
Check antenna placement and receiver power if range is poor.
Confirm the system is a Sentry 300S single swing or Sentry 300D dual swing gate opener when the part is being used on a Sentry operator.
Match the part number from the existing accessory, manual, or product label when available.

Professional Advisory

Program and test one button at a time. Keep people, vehicles, and tools clear of the moving gate or garage door during receiver programming and testing.

Product Questions

What is the main difference between 030212 and 030210?

030212 is the 4-button LCR transmitter. 030210 is the 2-button version. Both require a compatible USAutomatic LCR receiver.

Can one 030212 control a gate and garage door?

Yes, when each device has a compatible LCR receiver installed and wired correctly. The remote itself does not make an incompatible garage opener compatible.

What frequency does the 030212 use?

The 030212 LCR transmitter operates on the 433.92 MHz USAutomatic/Sentry LCR fixed-code platform.

Why do only some buttons work?

Only buttons paired or coded to compatible receivers will operate. Unused buttons or buttons assigned to the wrong receiver will not control the device.

Is this remote compatible with all USAutomatic openers?

No. It is for compatible LCR receiver systems. USAutomatic high-security or different receiver families may require a different transmitter.
