Installation Manual

• Uses Linear’s popular MegaCode format.

• 12–24 Volts AC or DC.

• Auto voltage sensing — no jumpers to set.

• Single relay and two relay models.

• Supplied with whip antenna, three feet of

coaxial cable, and bulkhead connector.

The MGR and the MGR-2 are two auto sensing

MegaCode 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 MGR

and MGR-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 MegaCode is a popular radio format for gate

receivers, making the MGR and the MGR-2 compatible

with all MegaCode transmitters, including two and four-

channel models and wireless keypads. MegaCode uses

a frequency of 318 MHz and features over one million

radio codes to all but eliminate any possibility of code

duplication. It offers simplified programming via the

receiver's learn mode.

The MGR has a single relay and replaces the

MDRG Linear gate receiver. It is designed for use with

automatic gate operators or systems where a remote

antenna is needed. The MGR-2 comes with two relays. It

will operate two gates, one gate and an obstacle sensor,

or two obstacle sensors. 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.
