Introduction: Thank you for your purchase of a Knoll IR155 infrared connection module. This module is the heart of a scalable infrared repeater system. The IR repeater system can pick up a remote control signal and relay it on wires to the inside of a cupboard or another location up to 1000’ (or more). Features:  Easy to install and easy to use  No maintenance  Connect up to twelve infrared receivers  Connect up to eight emitters to four emitter ports  One emitter port is dimmable for use with oversensitive components.  Industry standard color coded jacks.  Knoll PS1205 power supply recommended Installation Tips 1. Follow all local electrical & building code requirements. 2. The IR155 is usually mounted with the stereo and/or video equipment it is helping to control. 3. Wires to the infrared receivers can be solid or stranded, shielded or unshielded with a minimum of 28-gauge for runs under 200’, 22-gauge for runs under 500’ and 20-gauge for runs up to 1000’. Wires can be looped from infrared receiver to receiver or home run. Home runs normally offer more reliability and future flexibility.

Knoll infrared receivers can be mixed and matched in larger systems with up to 12 Knoll infrared receivers per system. 5. When connecting Knoll infrared receivers to the IR155 detachable connector, make sure the infrared receivers are wired in parallel only. Some Knoll infrared receivers have a red plug connected. It can be connected to the IR155 red jack. If the wire length is longer or the receiver does not have a red plug use the following procedure: Connect the infrared receiver(s) 12V, GND and SIG terminals to the corresponding IR155 screw terminals. Prepare the wire leads to and from the IR receivers by stripping about ¼” of the insulation from each of the three leads. Twist the strands tightly together so that they do not stick out of the connector and cause a short circuit. Strictly observe polarity. See the Knoll infrared receiver manual for wire identification. 6. Next, plug the single or dual emitters into the IR155 connection block and position the emitters over the component to be controlled infrared receiver window (and glue it down). Clear acrylic glue works well if the included double sided sticky tape doesn’t work as needed. Emitter port 1 is dimmable. In most cases the pot should be turned fully on (fully clockwise). In certain cases when emitters are attached to overly sensitive components (that IR signals don’t reliably work) emitter port 1 can be helpful. If this is the case attach the emitter and start by dialing back the emitter pot ½ way and experiment to see if the infrared signal is more reliable. Adjust the pot further as needed. 7. Plug in the PS1205 power supply. 8. The infrared system is usually left plugged in all the time (to an unswitched outlet) as it uses very little standby power. 9. Test the infrared system to see if it is working properly. Bright sunlight and passive infrared security systems can lower the distance that remote controls can work with the Knoll infrared receiver(s). Note: When using more than 150 foot (50m) lengths of shielded wire it may be necessary to add a 470 ohm 1/4w resistor between the IR155 “GND” and “IR OUT” to discharge cable capacitance.
