MOUNTING
The OSC-200 is designed to be recess or surface
mounted to a ceiling.
Step 1: Install Base Unit
• Determine the location of the sensor according to the
detection pattern shown in Figure 1a.
• Remove the cover screw to open the sensor housing
as shown in Figure 1b.
• Remove the circuit board by bending the tab outward
(Figure 1b.)
• Screw the base of the sensor housing to the ceiling
through the knockout holes (Figure 1b.)

Step 2: Wiring
•
Feed the cable through one of the corner knockout
holes (Figure 1b.)
• Reinsert the circuit board.
• Turn the screw for each terminal counterclockwise
(Figure 1b.)
• Connect the cable to the corresponding terminals as

Step 3: Walk Test
Before beginning test, make certain that the On and Off
Delay jumpers (located on the circuit board) are
connected in the “A” positions as shown in Figure 3. If
they are not, follow the procedure under the section titled
On/Off Delay Settings to rearrange the jumpers to location
“A.” Replace the sensor housing and tighten screw.
