CONNECTIONS
Punch-Down Block Connections
1. Strip approximately 1" to 11/2" from the outer jacket of the cable being connected to the
Source. DO NOT strip the individual conductors.
2. Using a proper 110 punch-down tool, connect each of the wires to the appropriate
terminals on the Source Keypad punch-down block (refer to
Figures 13 & 14
). When
making connections to the Source Keypad punch-down block ALWAYS pull the wire
toward the middle of the keypad . Pulling the wires toward the outside will create
difficulty when installing the keypad into the Mounting Bracket and will probably cause
wires to become disconnected.
3. Prior to installing the keypad, attach the included Wire Retainer to the back of the Source
Keypad as shown in
Figure 15
. Remove the adhesive backing from the wire retainer and
attach with the wire tie oriented vertically as shown, with the retainer lock at the bottom.
Pull the retainer over the wire and down through the lock as shown. This will help
prevent the wires from becoming disconnected during installation.
4. Terminate and connect the head-end connection as appropriate.
