3. Check the phones on the premises for dial tone and the ability to dial out and
make phone calls. If phones do not work correctly, check all wiring and
correct where necessary. Proceed to the “Troubleshooting” on page 76 of this
manual if problems persist.
Connecting the AC Power Transformer
Note: If you plan on connecting an alphanumeric touchpad to the programming
touchpad header on the panel, do not connect it until after the panel is powered
up. Refer to “Entering Programming Mode.”
The panel must be powered by a plug-in stepdown transformer that supplies 16.5
VAC, 25 VA (60-822 or 60-679-CN). Connect the power transformer to the panel
as shown in Figure 18 on page 24.
Caution: Do not plug in the power transformer at this time. The panel must be
powered up using the sequence of steps described in “Powering Up the Panel”
on page 24.
