The MR1 IR receiver has been designed for mounting in very small spaces. It may be mounted
under shelf edges, cabinet ledges, etc. – anywhere an inconspicuous appearance is desired.
The high sensitivity of these receivers allows reception of IR commands up to 25 feet away.
FEATURES
• Very small package.
• Works in a standard 3-wire system.
• System talk-back LED.
• Includes 3-Terminal Block for easy extension of 18" ribbon cable.
• 12 units may be powered by one PS1 power supply.
• Has a 7 Foot, three-conductor ribbon cable with stripped and tinned ends.
• Circuitry contained in a shielded chassis.
SPECIFICATIONS
• Infrared carrier frequency bandwidth: 30 - 100 kHz.
• Reception range: up to 25 feet.
• Nominal reception angle: +
55 degrees off axis.
• Cable requirements: 3-conductor, 24 to 18 gauge (unshielded OK).
• Maximum transmission length: One mile using 18 gauge wire.
• Maximum current output: 100 mA.
• Maximum number of directly driven IR Emitters: 4 (8 if 4 E2 emitters are used).
• Dimensions: 7/16" x 5/16" x 2-1/8" (11.2mm x 8.5mm x 55mm).
• Power requirements: 12 volts DC @ 10 mA.
INSTALLATION
MR1. These units are intended to be wired to the input terminals of Sonance Connecting
Blocks or other devices, using the supplied 3-terminal block in the remote room location. A 3-
conductor cable (24 gauge up to 200', 22 gauge up to 600', 20 gauge up to 2000', 18 gauge up
to 5000') is run to the main room. Connections are then made to a Sonance connecting block,
power supply, and emitters as shown in the following illustration of a typical basic system:
