3. If longer wires are required for the IR320, solid or stranded, |
shielded or unshielded with a minimum of |
under 200’, |
runs up to 1000’. Wires can be looped from IR320 to IR320 or |
home run. Home wire runs normally offer more reliability and |
future flexibility. |
4. IR320s can be mixed and matched in larger systems with up |
to 10 Knoll infrared receivers. |
5. When connecting multiple Knoll infrared receivers to the |
IR155 detachable connector, make sure the infrared receivers |
are wired in parallel only. For a single IR320 connected to the |

Connect the infrared receiver(s) 12V, GND and SIG terminals |
to the corresponding IR155 screw terminals. Prepare the wire |

together so that they do not stick out of the connector and |
cause a short circuit. Strictly observe polarity. |

6.Next, plug the single or dual emitter(s) into the Knoll connection block and position and attach the emitter output to the source components infrared receiver window.

7.Plug in the power supply. The Knoll PS1205 can power one to ten infrared receivers, one connection block and one to four single or dual emitters.
8.The infrared system is usually left plugged in all the time (to an unswitched outlet) as it uses very little 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 an IR320 receiver.
