Installation  
Cat wires from rooms with more than one VC201 are run from one VC201 to  
the other then home run back to the controller.  
Installing the digital volume control system should be relatively  
easy. With a bit of planning, it will give trouble free service  
for years.  
It is very important to use a top quality RJ45 8/8  
crimper tool. We strongly suggest using a cat 5  
RJ45 electronic tester to verify the wire conductors.  
Basic System Layout and Pre-Wiring: See “Typical Wiring Diagram” on  
the centerfold page. The VC224pm and VC226pm make a noticeable “click”  
sound when changing volumes. We suggest mounting it in a low voltage panel,  
electrical room, closet, etc. We do not suggest connecting more than one  
VC224pm or VC226pm to a single amplifier or receiver, even if it is a high  
power model because a variety of power sharing problems can occur.  
One or two VC201 keypads can work on a single room or zone but only one  
VC201i can be connected to a single VC224pm or VC226pm room or zone.  
The VC200 keypad does not work with this system.  
Connection to Stereo Equipment:Remove the VC224pm orVC226pm green  
four-position speaker connector labelled "INPUT". The stereo amplifier or  
receiver outputs (left and right) are connected to this VC224pm or VC226pm  
connector. Be very careful to observe the correct polarity. This controller  
uses independent floating grounds so bridged amplifiers can be used safely.  
VC224pm and VC226pm controllers are rated for  
use with maximum 120 watt per channel amplifiers.  
DO NOT use higher-powered amplifiers with this  
product for safety reasons.  
Use the standard T568A wiring practices to run a cat 5 or cat 3 wire from  
the keypad or controller to the VC224pm or Vc226pm. If more than one  
keypad controls a single VC224pm or Vc226pm room, daisy chain the cat  
wire from keypad to keypad. If the VC226pmi is notlocated next to the  
stereo, run a single eight-conductor cat 3 or cat 5 wire run and four  
speaker wire conductors from the stereo to the controller for the power  
supply, the infrared system, future upgrades such as paging override and of  
course the steeo speaker sound.  
The amplifier or receiver must be rated for four ohm speaker use to work  
properly with the VC224pm or VC226pm controller. Connect the controller  
to the amp or receivers speaker A or speaker B terminals. Wire the VC224pm  
or VC226pm connectors labelled “ROOM1", "ROOM2" etc. directly to the  
correct room speakers, again strictly observing polarity.  
From each speaker run a home run fire ratedtwo-conductor speaker wire  
to the VC224pm or VC226pm. To save time and money, most installers run a  
four-conductor speaker wire from the VC224pm or VC226pm to the closest  
appropriate speaker and then run a short two-conductor speaker wire to  
the other speaker. If there is more than one pair of speakers connected to  
a single VC224pm or VC226pm zone, the speakers can be wired in series or  
parallel whichever makes the impedance closest to 4 or 8 ohms. Do not  
attemptto make the final combined speaker impedance less than 4 ohms.  
Power Requirements: The VC224pm and VC226pm are shipped with a 12VDC  
500mA (or more) power supply (supplies power to the keypads). If possible,  
connect the 12vdc power supply to the switched outlet on the rear of the  
amplifier or receiver. This wiring causes the VC224pm or VC226pm  
controller to reset to its selectable “boot up” every time the receiver or  
amplifier is turned on but when the power is off the IR section of the  
VC201i will not work. If the IR is required to work all the time, then the  
controller power supply must connected to an unswitched outlet.  
Connecting VC201/VC201i keypads to VC224pm and VC226pm controllers:  
Use a single cat5 wire using all eight conductors (usually run inside a wall).  
Always use standard T568A Cat 5 wiring practices (shown below). Use the  
correct wire pairs. Polarity is VERY important! The stereo signal is not  
routed to the keypad, just the digital control signals. Signals from an  
infrared receiver (if used) are routed down the same Cat 5 wire. If more  
than one keypad (VC201, not VC201i) is to be connected to a VC224pm or  
VC226pm controller, the wires to the keypads are paralleled. continued..  
Installer Selectable “BOOT UP”: The VC224pm and VC226pm allow the  
installer to select how the volume control “boots up” in each room when the  
controller first receives 12vdc power. For this feature to work, be sure to  
plug the 12vdc power supply to the switched AC outlet on the rear of the  
receiver or amplifier. Please note #6/12 and S/Mute labels are inverted  
on zones 2, 4 and 6 on the version 1.3 board.  
To always Start MUTEed make sure the shunt on the right side of the  
controller room number labelled “S/MUTE” is in place. Remove this shunt and  
this room starts with the music on.
