GE Concord 4 "Service Touchpad Mode" for quick programming Concord 4 or Express

This mode saves the installer or service tech from accidentally programming his or her programmer's serial numbers into the control panel's memory.
To enter program mode using a programming
touchpad:
1. Connect the red, black, green, and white wires from
the programming touchpad cable (60-791) to the
power and bus wires/terminals on an alphanumeric
touchpad, matching the +12V (red), Bus A (green),
Bus B (white), and GDN (black) on each.
2. Make sure the system is powered up and disarmed.
3. Connect the plug on the cable to the panel
programming touchpad header.
4. Press 8, 4321, 0, 2.
The touchpad sounds one short beep.
5. Press * and verify that the display shows SERVICE
TOUCHPAD ACTIVE.
