Delta-3  GRD-2: 2-Channel Gate Receiver

The Delta-3 GRD-2 is a 2-channel Gate Receiver designed for use with automatic gate operators or
systems where a remote antenna is needed. The GRD-2 can operate two gates, one gate and an obstacle
sensor, or channel one can open the gate and channel two can close the gate. The receiver uses the
Delta-3 radio format, with 256 possible codes for each channel, set by dipswitch.

Features
Uses Linear’s popular Delta-3 format
Auto voltage sensing - no jumpers to set
Two Form ”A” (normally open) relays rated at 30 Volts AC/DC up to 5 Amps each
Supplied with whip antenna, three feet of coaxial cable, and bulkhead connector
Power: 12 - 30 VAC or 10.5 - 30 VDC
Dimensions: 3.625 x 5.25 x 1.5 inches
Order number: DNR00102

The GRD and the GRD-2 are two auto sensing Delta 3 format gate receivers from Linear. They eliminate any
chance of damage to either the gate operator or themselves from running off the wrong voltage.Nearly all
gate operators offer either 24 or 12 volts AC or DC as accessory power. Because the GRD and GRD-2 are
auto sensing, each receiver recognizes the gate operator’s correct voltage. As a result, installers can be
assured of always having the correct model gate receiver on the truck. The two receivers can operate
from 12-30 volts AC or 10.5-30 volts DC and are normally powered from the gate operator. Their relay
contact(s) are rated at 5 amps @ 30 volts AC/DC.
Linear’s Delta 3 is a popular radio format for gate receivers, making the GRD and the GRD-2 compatible
with all Delta-3 transmitters, including two and fourchannel models. It uses a frequency of 310 MHz and
offers 256 programmable codes. Programming of the GRD and GRD-2 is easy. Codes are set using the 8-
position coding switches inside the units. The GRD has a single relay. It replaces two different Linear gate
receivers, the DRG and the DRG-LV. It is
designed for use with automatic gate operators or systems where a remote antenna is needed. The GRD-2
comes
with two relays and replaces Linear models DRG-2 and DRG-2-LV. It will operate two gates, one gate and an
obstacle sensor, or channel one can open the gate and channel two can close the gate. Both models
come with a 9-inch local antenna, three feet of 75 ohm coaxial cable, and a bulkhead connector for
locating the antenna outside the gate operator enclosure
