STEP 12:
Strip
3
/16” off the ends of the low voltage wire and
twist tightly. These wire ends will be attached to
the control board at the 18VAC terminals located
on the POWER IN terminal block (see Illustration
L). Wire sheathing should not come in contact with
terminals, however, it should not be stripped so far
that wires can come in contact with one another
(see Illustration K).
Insert one transformer wire
into an 18VAC terminal.
Insert the other transformer
wire into the remaining
18 VAC ter mi nal (s ee
illustration L). Transformer
wires can be connected to the
18VAC terminals regardless
of color.
Tighten set screws against
exposed end of wires (see
Illustration K). A dab of
household petroleum jelly
on each wire end will help
prevent corrosion.
The ACCESSORY terminal
block provides the connection
point for safety loops, wands,
push buttons, intercoms, card
readers, etc. See page 27
for more information about
connecting accessories.
STEP 13:
Plug the transformer into the electrical outlet. Check to see
if the green LED on the control board is on. If it is not, see
the Troubleshooting Guide on page 30.
NOTE: Use of a surge protector is strongly recommended.
