I ntroduct ion The MS-1 is a miniature IR sensor designed for use with the Niles Infrared Repeating systems. Installed in a remote room location, the MS-1 receives the IR commands transmitted from your existing hand-held remotes in that room. The commands are carried via a small 2-conductor shielded cable to your A/V equipment in anoth- er room, an[...]

Features and Benefits The MS-1 offers a number of improvements over other miniature IR sensors. ● Small size of only 1 /2" diameter by 2-5/1 6" long — fits almost anywhere. ● Universal system — compatible with virtually all brands of A/V equipment and remote controls. ● Excellent IR receiving range — you get 1 8 to 3 0 feet of[...]

Installation Considerations T ype of Cable The MS-1 connects to the Niles Infrared Systems with an individual home run of 2-conductor shielded cable. Recommended cables are Niles data grade IR cable, W est Penn D291, Belden 8761, Carol C2516 or equivalent, made of two 22 gauge (or larger) conductors surrounded by a foil shield and a bare drain (gro[...]

Receiving Range and Pickup Angle The receiving range of the MS-1 will vary according to the IR output strength of the remote control being used. Remote strength varies among brands depending on the number and size of batteries used, and how many IR emitters the remote has. For example, remotes that operate on two small AAA batteries and have only o[...]

Avoiding Electrical Interference Avoid locating the MS-1 near any potential sources of electri- cal or optical noise, such as light dimmers, florescent lighting fixtures, low-voltage lights, and neon lights. If you are installing the MS-1 near a television, keep it at least 6" away from the top, bottom or sides of the TV to avoid interference.[...]

Avoiding Optical Feedback If installing the MS-1 in the same room as an IR flasher , it is possible for the flasher's IR output to be picked-up by the MS-1. This effect, known as an optical feedback loop, can cause erratic operation. Optical feedback is similar to acousti- cal feedback: the howling or whistling sound heard in a P .A. system wh[...]

2. Hold the MS-1 so that the front of it is facing you, mak- ing sure that the lens is in place. Screw the new bezel onto the MS-1 by turning it clockwise. 7 M INIA TURE I NFRARED S ENSOR Figure 1 Removing the Bezel[...]

9 M INIA TURE I NFRARED S ENSOR Installation If you are installing the MS-1 into an existing wall, take time to consider any possible obstructions which may be hidden inside the wall, such as wood and metal studs; electrical, tele- phone or other types of wiring; plumbing; conduit; old wall safes; etc. 1. Determine a mounting location for the MS-1.[...]

Operation This manual contains instructions for the MS-1 only . For spe- cific information on the adjustment and operation of your Niles Infrared system, please refer to the instruction manual included with your Niles Main System Unit. Operation of the MS-1 is straightforward. Simply aim your hand-held remote at the MS-1. Y our IR command is instan[...]

T roubleshooting The "flash-back" LED on the front of the MS-1 is a useful troubleshooting aid. The LED should light only when a remote command is being received. If the MS-1 does not work, and the LED does not light at all: 1. T est the remote control(s) by operating the A/V equip- ment directly . Replace the batteries if needed. 2. Doub[...]

M INIA TURE I NFRARED S ENSOR 13 There are many methods for reducing interference. Which solution is best for you depends on your situation. Contact Niles T echnical Support at 1 -800-289-4434 if you require further assistance. If the LED on the MS-1 "flickers" dimly , and the MS-1 functions normally , there is no cause for conce rn.[...]
