LC 1200 Manual Push Button Override (PBO) 7-3
Wiring to the LC Unit
You will need 22-gauge, 4-conductor plenum-
rated cable for this connection.
Note:
The following instructions assume that the
Keypad and LC unit are already wired (see
Chapter 6 for these wiring instructions). If
desired, you can splice into these wires when
connecting a PBO for easier installation.
To wire the PBO to the LC unit, refer to Figure
7.2 and use the following instructions:
1. Remove the Keypad from the white
back box.
2. Remove the LC unit cover and screws.
3. Using BLACK wire, jumper the
negatives (-) of the Red and Yellow
LEDs together, then to the right prong
of the PBO plug (with a spade crimp
connector).
4. Continue from the right prong of the
PBO plug (with a spade crimp
connector) to the P3-4 “Ground” of the
LC unit).
Note: If desired, you can splice into the
BLACK wire already present from the
connection of the Keypad to the LC
unit.
5. Using RED wire, connect the positive
(+) side of the Yellow and Green LEDs
on the PBO to a Butt Splice, then to P3-
3 “+12V DC” of the LC unit.
Note: If desired, you can splice into the
RED wire already present from the
connection of the Keypad to the LC
unit.
6. Jumper P2-6 “Alarm Comm” and P3-3
“+12V DC” on the LC unit.
Note: This jumper should already be
present if the Keypad has been wired.
7. Using GREEN wire, connect the
negative (-) side of the Green LED to
P2-2 “Reset In” on the LC unit.
Note: If desired, you can splice into the
GREEN wire already present from the
connection of the Keypad to the LC
unit.
8. Using WHITE wire, connect the
positive (+) side of the Red LED to P2-5
“Alarm NC” of the LC unit.
Note: If desired, you can splice into the
WHITE wire already present from the
connection of the Keypad to the LC
unit.
9. Using RED wire and a spade crimp
connector, connect the left prong to the
PBO plug to Pin 5 of the Keypad.
10. Replace the LC unit cover and screws.
