Wall Port Installation 
Pick an unobtrusive location close to the controller that1. 
all cables (speaker and keypad) can be routed to.
Install an electrical box, using a UL/CSA approved plastic2. 
single-gang (18 ci or deeper) electrical box. If there will 
be two controllers you should use two single-gang 
boxes separated slightly to allow space for the cables. 
Route CAT-5 wire from the electrical box to the four keypad3. 
locations. Route the speaker cable from the electrical box 
to the corresponding speaker locations. Label each set of 
cables with the zone and location.
Terminate each CAT-5 wire with a RJ-45 plug using the4. 
T568A standard conguration. 
Strip 1 to 2 inches (2.5 to 5 cm) o the end of each speaker5. 
cable jacket. Then strip 1/4 inch (0.7 cm) of insulation o
each wire.
Twist the speaker wire strands together so there are no6. 
strands separated from the bundle. 
Insert the proper speaker wire, matching channel7. 
and polarity for all four wires. Tighten the screws until 
the wires are secured in the terminal. 
Cable as follows (standard 4-conductor): 
White -- L+ (left channel positive), Green -- L- (left channel 
negative), Black -- R- (right channel negative) and Red -- 
R+ (right channel positive). 
Check to make sure there are no stray strands of wire8. 
outside the terminals. If there are, remove the wire, twist 
the strands together, and reconnect the wire to the 
terminal.
Complete the same steps for the remaining zones. Plug9. 
each of the RJ-45 plugs into the corresponding keypad 
zone jack on the rear of the wall port. Note: All four 
connections from the controller to the wall port must be 
made, even if there are less than 4 keypads connected 
to the system. Cables between the wall port and the 
controller must match numerically (#1 on the wall port 
to #1 on the controller).
Mount the wall port in the electrical box. Push any extra10. 
cable back into the wall. Screw the wall port plate to the 
electrical box. Attach the trim plate to the wall port.
