DESCRIPTION
The GRD is a digital receiver designed for use with automatic
gate operators or systems where a remote antenna is
needed. The GRD-2 will operate two gates, one gate and
an obstacle sensor, or channel one can open the gate and
channel two can close the gate.
All of the Delta-3 transmitters, including the two and
four-channel transmitters, are compatible with the GRD.
The Delta-3 radio format provides 256 different digital codes.
The codes are set using the 8-position coding switches in
the units. In order to avoid the possibility of duplicating codes
in adjacent systems, factory set codes should not be used.
The receivers can operate from 12-30 volts AC or 10.5-30
volts DC and are normally powered from the gate operator.
The relay contact(s) are rated at 5 amps @ 32 volts AC/DC
NEC Class 2 circuit.
The GRD has a “F” connector for attaching an antenna. The
receiver is supplied with a 9-inch local antenna, a three foot
75 ohm coaxial cable, and a bulkhead connector for
mounting the antenna outside the gate operator enclosure. STEP 1 Open receiver case. To open case,
squeeze sides of case and rotate upward.
STEP 2A GRD & GRD-2 Channel 1 code
setting. T o s e t a c o d e , s e l e c t a n y v a l i d
combination of ON and OFF positions for the
switch keys numbered 1- 8. Use a paper clip to
set the eight keys.
STEP 2B GRD-2 Channel 2 code setting.
Select any valid combination of ON and OFF
positions for each of the switch keys numbered
1 - 8. Use a different code combination than that
used for channel one switch.
STEP 3 Transmitter code setting. Locate
the coding switch on the transmitter and set the
eight keys identical to those on the desired
channel of the receiver. Be sure they match
exactly. I f u s i n g a t w o o r f o u r - c h a n n e l
transmitter, refer to the coding instructions
included with the transmitter for proper system
coding.
STEP 4 Connect receiver relay output.
Connect the appropriate channel wires (Ch. 1 -
two gray wires), (Ch. 2 - two yellow wires) to the
appropriate activation terminals on the gate
operator.
STEP 5 C o n n e c t r e c e i v e r t o p o w e r .
Connect the red power input wire to the 24VDC
radio power and the black wire to the common
terminal on the gate operator. Alternately connect
wires to a 12-24 VAC transformer.
STEP 6 Mounting the receiver. U s e t h e
screws provided to mount the receiver within the
operator housing. This provides protection from
the elements. Secure case with case screws.
STEP 7 Connect antenna. C o n n e c t t h e
coaxial cable to the “F” connector on the receiver.
Drill a 3/8" hole on the top of the operator housing
for the bulkhead connector. Insert the connector
and secure it with the nut and lock washer.
Connect the cable and antenna to the bulkhead
connector.

IMPORTANT !!!
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.
1
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.
1
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.
1
Changes or modifications to the device may void FCC compliance.
1
Infrequently used radio links should be tested regularly to protect against undetected
interference or fault.
1 A general knowledge of radio and its vagaries should be gained prior to acting as a
wholesale distributor or dealer, and these facts should be communicated to the ultimate
users.
