" 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
18VAC
terminal (see
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
