Product Overview
Leviton's OSSMT multi-technology Decora brand style wall switch occupancy sensor is used to provide automatic lighting control for energy savings and convenience in a variety of commercial applications, including: retrofit- private and executive offices- conference rooms- storage areas- restrooms- classrooms- lounges- training areas. The OSSMT provides for automatic switching of incandescent lamps, low-voltage lighting with electronic and magnetic transformers and electronic and magnetic fluorescent ballasts. The OSSMT features a manual override switch that can be used to keep lights off while an area is occupied, which may be desired in conference rooms, classrooms and other areas during video presentations. Designed to replace a single-pole Decora wall switch, it fits in a standard wall box. The OSSMT-MD model requires a neutral and a ground connection. For retrofit applications, the OSSMT-GD model does not require a neutral wire for installation.

- Convenient push-button provides manual on/off light switch at any time
- Exclusive automatic "walk-through" sensing increases energy savings by shutting lights within 2-1/2 minutes after momentary occupancy
- OSSMT is ideal for private and executive offices, conference rooms, storage areas, restrooms, classrooms, lounges, and training areas or areas where minor motion is likely to occur
- Fast, simple installation: fits in a standard wall box and replaces a single-pole wall-switch
- No neutral, 2400 sq. ft. major and 400 sq. ft. minor motion coverage

Asked by Butterfly May 16, 20181
AnswerHi , Thank you for choosing Leviton. Call backs are referring to an installer being called back to a job site, after install to adjust the setting of the device. Time delay is the amount of time where there is no motion present before the sensor switches off and the sensitivity is how close to the unit you can get before it responds to motion.
I need a manual for setting up this switch for time delay, and sensitivity. cat.# ossmt

Works quite well but will require patience in setting up the 3 control dials, that control TIMEOUT, AMBIENT LIGHT LEVEL, AND THE RANGE (distance).
The minimum TIMEOUT setting is 30 seconds, up to 30 minutes. This controls the length of time it will stay on after detecting motion or a change in the "background heat" or PIR. Passive infra-red.
It comes factory adjusted but you will have to carefully read the setup instructions and fine tune the sensitivity and wait 30 seconds the see the effect. I took me 20 minutes to correctly adjust the settings for the location in a hallway. I works great after setup.

Be sure to completely read the instructions. There are several options to choose from when looking for a motion detector switch. I needed one for a laundry room which is also a utility room containing the furnace and water heater. This switch DOES NOT work in areas with drafts, The moving hot air affects the switch and keeps the light on when the room is empty. This switch was returned..
