3b. Wiring (pre-wired).

‡Route wire from wall to Safe-T-Beam®sensors (Fig. 4-5b).

‡Splice pre-wiring to shortened sensor wire, match wire pairs dash-to-dashand plain-to-plain.

-Trim sensor wire to approximately one foot (1 ft) from sensor.

-Split and strip ends of sensor wires and

pre-wired wires (Fig. 4-7).

- Splice wires together with (provided)

wire nuts.

‡ Route wire from ceiling to power head

(Fig. 4-5b).

‡Securely fasten wires where they exit wall and ceiling as you go.

– Use insulated staples.

– Staples should be snug only.	Insulated
	Staple

CAUTION

Staples which are too tight can cut or pinch wires. Cut or pinched wires can cause the Safe-T-Beam®System to stop working. When using the insulated staples, make sure you fasten them only as tightly as needed to hold the wire snugly.

4. Split and strip ends of sensor wires (Fig. 4-7).

NOTE: For rear cover locate Box 4.

5.Attach Safe-T-Beam®wire to power head wire terminal.

‡Route Safe-T-Beam®wires through wire guide.

–Insert wire into terminal holes and lightly press in the orange locking clips above each terminal hole. (You can use a pencil or small screwdriver to comfortably reach in and lightly press down locking clips.) Insert white wires to 'even' numbered terminal holes and striped wires into 'odd' terminal holes (Fig. 4-5b).
