DESCRIPTION The Delta-3 DR4V & DR4-12 digital receivers are
four-channel wireless radio controls designed for use with
automatic garage/gate operators and access control systems. The
receivers can be activated by any of the Delta-3 format
transmitters. Receivers must be mounted at least 8 feet apart.
STEP 1 Locate coding switch. Locate the digital coding switch
which is recessed in the center of the back of the receiver case.
Note that the coding switch has eight keys. The keys are numbered
1 through 8. Key No. 1 and Key No. 2 are not used for coding the
receiver; their functions are permanently wired on the circuit
board.
DR4V
DR4-12
The Delta-3 radio format provides 256 different digital codes. The
codes are set using the 8-position coding switches in the units.

recoded by the installer prior to operation.
In order to avoid the possibility of duplicating codes in adjacent
systems, factory set codes should not be used. In addition, among
the valid codes available, four others should not be used. These
include: all keys set ON or OFF and keys set alternating ON/OFF.

STEP 2 Code the receiver. Pick any combination of ON/ OFF
codes and set them on switch keys 3 through 8. Ignore Keys 1 and
2. The ON position is when the top of the switch is down. The OFF
position is when the top of the switch is up and the bottom is down.
The code set on Keys 3 through 8 on the receiver must now be
matched by all transmitters used in the system.
STEP 3 Code the transmitters. Remove the battery access door
located on the back of the transmitter case to set transmitter codes.
Transmitter keys 1 and 2 determine which channel the transmitter
will activate. Keys 3 through 8 must match keys 3 through 8 on
the receiver. Refer to transmitter code set instructions to code
multi-button transmitters.
STEP 4A Connecting receiver (using transformer power). A
Model T12A (used with DR4-12) or 524 (used with DR4-V)
transformer can be used to power the receiver when connecting
receiver to any operator. Connect as shown, then plug the
transformer into a convenient (unswitched) 120 VAC outlet.

RADIO POWER
Linear radio controls provide a reliable communications link and fill an important need in portable wireless
signaling. However, there are some limitations which must be observed.
BROWN

RED
✶ For U.S. installations only: The radios are required to comply with FCC Rules and Regulations as Part 15
devices. As such, they have limited transmitter power and therefore limited range.
✶ A receiver cannot respond to more than one transmitted signal at a time and may be blocked by radio signals
that occur on or near their operating frequencies, regardless of code settings.
