3. Wiring (cont’).
• Securely fasten wires to wall as you go.
– Use insulated staples (included).
– Staples should be snug only.
• Make wire attachments at “STBs.”
– Split and strip wire ends to be connected
as shown (Fig. 2-6).
– Loosen terminal screws.
– Insert wire under flat plate and tighten screw.
It does not matter which wire, white or
striped, goes on which terminal (Fig. 2-7).
• Make wire attachments at power head.
– “STBs” are connected to terminals #2 and #3
on power head (Fig. 2-8). It does not matter
which wire, white or striped, goes on
which terminal.
4. Check the following.
• Insure that no part of door or its hardware is
in path between lenses of source and sensor.
• Insure that tops of lenses are between 5"-6"
above the floor (Fig. 2-9). The brackets are
flexible, and can be adjusted slightly if needed.
NOTE: “STB” alignment check will be
performed following connection to electrical
power (see page 20). DO NOT PLUG IN YET!
Staples which are too tight can cut or pinch wires. Cut
or pinched wires can cause the “STB” System to stop
working. When using the insulated staples, make sure
you fasten them only as tightly as needed to hold the
