M I N I A T U R E I N F R A R E D S E N S O R MS-1 MicroSensor TM Miniature IR Sensor TABLE OF CONTENTS Introduction Introduction 1 The MS-1 is a miniature IR sensor designed for use with the Niles Infrared Repeating systems. Features and Benefits 2 Installation Considerations 3 Installation 9 Operation 11 Troubleshooting 12 Specifications 14 Installed in a remote room location, the MS-1 receives the IR commands transmitted from your existing hand-held remotes in that room.
M I N I A T U R E I N F R A R E D S E N S O R Features and Benefits The MS-1 offers a number of improvements over other miniature IR sensors. ● Small size of only 1/2" diameter by 2-5/16" long — fits almost anywhere. ● Universal system — compatible with virtually all brands of A/V equipment and remote controls. ● Excellent IR receiving range — you get 18 to 30 feet of remote control range (depending upon the strength of your handheld remote). ● 100% factory tested for pickup range and angle.
M I N I A T U R E I N F R A R E D S E N S O R Installation Considerations Type of Cable TOOLS REQUIRED • 1/8" Standard Slotted Screwdriver • Adjustable wrench or pliers • Wire Stripper 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, West 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 (ground) wire.
M I N I A T U R E I N F R A R E D S E N S O R 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.
M I N I A T U R E I N F R A R E D S E N S O R Avoiding Electrical Interference Avoid locating the MS-1 near any potential sources of electrical 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. Avoid running the MS-1's cable on the top of the TV, or near the back cabinet of the TV.
M I N I A T U R E I N F R A R E D S E N S O R 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 acoustical feedback: the howling or whistling sound heard in a P.A. system when the microphone is too close to the speaker. To avoid optical feedback: 1.

M I N I A T U R E I N F R A R E D S E N S O R 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, telephone or other types of wiring; plumbing; conduit; old wall safes; etc. 1. Determine a mounting location for the MS-1. Select a location where you will have access to the rear of the MS-1 after it is installed.

M I I N I A T U R E N F R A R E D S E N S O R Operation This manual contains instructions for the MS-1 only. For specific 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. Your IR command is instantly repeated to your A/V equipment.
M I N I A T U R E I N F R A R E D S E N S O R Troubleshooting 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. Test the remote control(s) by operating the A/V equipment directly. Replace the batteries if needed. 2. Double check the cable connections on all MS-1's and on the Main System Unit. Look for open, shorted or reversed wires.
M I N I A T U R E I N F R A R E D S E N S O R There are many methods for reducing interference. Which solution is best for you depends on your situation. Contact Niles Technical 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 concern.
