Occupancy Sensor

The Model OSC-200 Omnidirectional Occupancy Sensor automatically controls a HVAC ventilation system. A spherical Fresnel lens provides a 360° detection zone with the use of infrared technology. The integrated dual delay processor saves energy by eliminating false activation due to short-term occupancies. The Model OSC-200 is designed to be ceiling mounted, and is pre-wired for ease of installation.

Features:

Delay processor suppresses switch activation during momentary occupancy

Applications:

Lighting control

Building energy conservation

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

 Wiring:

Model OSC-200 is pre-wired for ease of use with 22AWG colored wires. Connect the wires as showin in figure 2

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.

Storage And Cleaning:

The sensor lens is the most delicate part of the Occupancy Sensor. The lens should be kept clean at all times, care should be taken when cleaning the lens using only a soft cloth or cotton swab with water or medical alcohol. Allow the lens to fully dry before using the sensor. The sensor should be installed or stored in an area of room temperature between -4 and 140ºF (-20 to 60ºC).

Maintenance:

After final installation of the unit, no routine maintenance is required. The Model OSC-200 is not field serviceable and should be returned if repair is needed (field repair should not be attempted and may void warranty). Be sure to include a brief description of the problem plus any relevant application notes. Contact customer service to receive a return goods authorization number before shipping.
