Single-channel Digital Receiver and
Code Setting and
The Delta-3 digital receiver and transmitter is a
single-channel wireless radio control designed for use with automatic
garage/gate operators and access control systems. All Delta-3 products (on the
same frequency) can be mixed and matched to suit your individual needs.
Delta-3 radio format provides 256 different digital codes. The codes are set
using the 8-position coding switches in the units.
Caution: All transmitters and receivers should be
recoded 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.
Where a number of receivers are to be
installed in close proximity (as in an apartment complex), install receivers at
least 5 feet apart. If receivers are installed closer than 5 feet apart,
blocking may occur.
After completing an installation, operate the
transmitter outside the building and check to see that the coded signal being
used does not interfere with neighboring garage door operators and/or security
systems. If interference is detected, select another code and check coded signal
again. Repeat if necessary.
1 Locate Coding Switches.
Locate the digital coding
switch for the receiver which is recessed in the center of the back of the case.
The transmitter coding switch is accessed by removing the battery access door
located on the back of the transmitter case. The keys are numbered 1 through 8.
The switches in the receiver must match the switches in all transmitters used to
operate the receiver.
2 Code Transmitter and Receiver.
Use a paper clip or other
pointed object (except a pencil or pen) to pick any combination of ON/OFF codes
and set them on switch keys 1 through 8 on the receiver and transmitter. 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.
3A Connecting receiver (using transformer power).
Where it is not feasible to obtain power from the operator, connect a model 524
transformer (accessory) to the receiver as shown below. Then plug the
transformer into a convenient (unswitched) 110 VAC outlet.
3B connecting receiver (using operator power).
Connect the receiver to the
garage door or gate operator as shown in the diagram. Power will be supplied
from the operator.
Ste3p 4 Remote Mounting. A mounting clip
is packaged with each receiver. To install the receiver, Attach the clip to the
mounting surface with screws. Position the two rectangular holes on the back of
the receiver over the clip and snap the receiver down into place.
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.
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.
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.
modifications to the device may void FCC compliance.
used radio links should be tested regularly to protect against undetected
interference or fault.

Operation is subject to the following two conditions: (1) This device may not
cause harmful interference and (2) this device must accept any interference
received, including interference that may cause undesired operation.
