Linear LLC has introduced the MGR and the MGR-2, two auto sensing MegaCode format gate receivers that eliminate any chance of damage to either the gate operator or themselves from running off the wrong voltage. Because nearly all gate operators offer either 24 or 12 volts AC or DC as accessory power, Linear has designed the MGR and MGR-2 to be auto sensing, so each receiver will recognize the gate operator's correct voltage (there are no jumpers to set). This built-in compatibility helps installers to reduce inventory and to always have the correct model gate receiver on the truck.
The MGR receiver is intended for use with automatic gate operators, systems where a remote antenna is needed, and other devices requiring a Form C relay. It replaces Linear's MDRG gate receiver. The MegaCode radio format provides over one million different code combinations and stores up to 40 transmitters. The MGR comes supplied 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. Its single relay is rated at 30 V AC/DC up to 5 Amps. It measures a compact 3.625 x 5.25 x 1.5 inches.
The MGR-2 is a 12-30 volt, two-channel, auto-sensing gate receiver with two relays that can operate two gates, one gate and an obstacle sensor, or two obstacle sensors. It offers two Form "A" relay outputs (each rated at 30 V AC/DC, and up to 5 Amps), wire leads for power and output connections, a Type "F" connector for local or remote antenna, a 9-inch local antenna with 3-foot cable and a bulkhead connector, a 40 code capacity, and the MegaCode format. Storage for up to 40 transmitters is standard. Dimensions are the same as for the MGR. Accessories for both gate receivers include the EXA-2000 directional remote antenna and the EXA-1000 omni-directional remote antenna.
