Door phone + keypad install

[EDIT: Wiring diagram to connect PAP2 to RC2a and E20B doorphone can be foundHERE]

Customer had already installed the wiring to the door.

Door phone and keypad mounting brackets installed.

Door phone installed, wiring keypad.

Wiring the keypad. 

Door phone and keypad installed (opps! the bracket for the keypad is upside down)

The reason the bracket was initially installed  upside down is because

the hole for the wire is on the bottom of the mount, not the top.

RC2A relay installed for door release via phone. 

Wiring everything up to the relays, dial tone and power supply. 

RC2A mounted and wired. 

Everything is done - keypad mount now mounted properly.

Hopefully the wire does not get damaged, since the hole for the 

wire is located at the bottom of the mount, and the wire is

run behind the bracket to the hole on the surface of the brick.  

Not shown is the Linksys PAP2 that was installed to connect dial tone to the E20B door phone and RC2A relay.

THIS DIAGRAM NEEDS TO BE MODIFIED IT IS NOT COMPLETELY ACCURATE: 

Here is a diagram that I put together that is close to how it is wired (all splices are actually done at the RC2A as you can see in photo above) **upon review of the above image, the solid green wire is going to the door strike not the striped green)***

Unconventional CAT5 terminations

Using a single CAT5 wire to terminate 2 data jacks. Since the Orange and Green pairs are only used in a CAT5 cable (not counting PoE or 10/100/1000 installs) the blue and brown pairs are not used, so they can be used to connect as a second "orange" and "green" pair on a second jack (as long as you terminate them both the same way on both ends of the cable). This should be avoided whenever possible, but can help to bring a second CAT5 jack somewhere that would be nearly impossible to pull a

This one is a little bit more creative. I needed to install push buttons for 3 door releases. My company did not want me pulling new runs. There was a CAT5 run near where the buttons needed to go to, but the fax line was connected to it. I installed a 8p8c connector terminated normally (568B) and split off the blue/white pair to a surface mount jack to connect the fax machine to. The remaining 3 pairs each went to a separate door release button. If needed to add more, I could have used a common wire for each button, to increase the amount of push buttons to a maximum of 5 + the fax dial tone. (or 7 if I did not need to have the dial tone working there.) Best thing about this installation, it is easily removable - or its concept can be used for other temporary applications using existing CAT5 wiring. 

Phone and network color codes

I know I posted a text version of the color code HERE  but to add to that I made some Images.

For network cables 568B is the most common used color code. To make a straight through or regular patch cord or jack both sides of the cable must be punched down to the same color code (either 568B or 568A). To make a cross over cable one end must be terminated as 568B and the other side as 568A) The only difference in terminations is that the orange and green pairs swap positions.

This is probably the color code that most people wiring a jack is looking for, What colors do the new CAT3/CAT5 colors go to inside of a phone jack since the colors are different. The first 2 (green/red+blue/white) are for line 1. The second pair does not usually need to be connected for residential customers unless they have a 2nd line. Some phone systems require both pairs to be connected.

 Here is the color code for the first 25 pairs of a telephone cable. This code repeats itself for cables larger than 25 pair by being wrapped in binder groups using the same color code (with the first 25 pair being wrapped in blue/white, and pairs 26-50 being wrapped in orange/white, etc.)

Need more than 25 pair? the colors will just continue to repeat, just wrapped in a different color binder, but here is what will be in the binders for 50 pair, 75 pair, 100 pair, and 125 pair.

I made and posted this image too quickly.
The outter binder colors (top and bottom) should be BLUE-ORANGE-GREEN-BROWN
