virtually any commercial (oce, retail), institutional (school,
hospital or clinic), or industrial (manufacturing) facility.
Three standard face plate widths are available:
CM-333: 2 ¾” x 4 ½” polycarbonate or stainless steel, ts on
single gang electrical boxes.
CM-333/N: 1 ¾” x 4 ½” polycarbonate or stainless steel, ts 1 ¾”
door frames or our CM-23D Jamb box.
CM-333/W: 4 ½” x 4 ½” polycarbonate or stainless steel,
ts on single gang, double gang or 4 x 4 electrical boxes. All
faceplates may be ordered up with a plain face, with the waving
hand symbol (/40), with the waving hand symbol and words:

square, and ush with the wall surface. (See Diagram 1)
b) If using a surface box, ensure it is secure & plumb.
2. Bring your 2-conductor wire through the back or side of
the enclosure and leave approximately 6” tail for wiring
connection.
3. Make the electrical connections to the device according to
the wiring section (following).
4. Using the dip switch located on the end of the unit, set the
operating mode. (See Section 6)
