DESCRIPTION
The DRG is a digital receiver designed for use with automatic
gate operators or systems where a remote antenna is
needed. The DRG2 will operate two gates, one ga te and a n
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 the DRG.
The Delta-3 radio format provides 256 different digita l codes.
The codes are set using the 8-po sition 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 16-24 volts AC or 20-30 volts
DC and are normally powered from the gate operator. The
relay contact(s) are rated at 5 amps @ 32 volts AC/DC NE C
Class 2 circuit.
The DRG 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.

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