Most occupancy sensors can also be programmed for vacancy mode.
- In occupancy mode, the sensor turns lights off when no one is present and turns them back on when an occupant enters the room.
- In vacancy mode, the sensor turns lights off when no one is present. An occupant entering the room would need to use a keypad to turn the lights back on.
You should determine which mode to use according to energy codes. You will be able to manually adjust the hypersonic and/or infrared sensitivity values on the units themselves.
Note: Sustained contact closures only.
To enable an occupancy/vacancy sensor to control certain groups in the installation, follow these steps:
1. Go to Device Control > Integration.
2. Select the appropriate N3 Satellite from the My Control Devices list on the left.
3. Go to the Analog I/O tab.
4. Consult the Ketra submittal to see which port the sensor is wired to. There are 4 Analog I/O ports on the N3 Satellite. In the Ketra submittal, “COM1” corresponds to Port 1, “COM2” to Port 2, etc.
5. Set the Port Type dropdown to "Contact Closure".
6. Set whether the port is normally open or normally closed. Each contact-closure port has two states—open and closed—depending on its input. Some sensors consider an occupied port to be open; others consider it to be closed.
7. Use the dropdown on the right to set the profile of the input.
8. Click Next.
9. Set additional configurations for the contact-closure input.Your options on this screen vary depending on the profile you chose.
- Vacancy Mode (Linked to Keypad): Select the keypad that controls the sensor’s groups. If the groups are controlled by multiple keypads, just select one of the keypads; the others will be accounted for under the hood.
- Vacancy Mode (Configure 1 scene): Assign a scene or show to play when vacancy is detected. Check the Off Trigger Delay box to enable the N3 to delay sending a wireless command after the sensor has reported unoccupied.
- Occupancy Mode (Linked to Keypad): Select the keypad that controls the sensor’s groups. Select that button that you want to turn on when occupancy is detected. Set the intensity level at which the scene or show should come on when occupancy is detected. The default is 50% intensity, but unless energy codes dictate otherwise, we recommend adjusting this to 100% to ensure full visibility for users entering the space.
- Occupancy Mode (Configure 2 scenes): Program a scene or show for occupancy and vacancy. Use the Occupancy On/Off dropdown to determine which setting you are assigning content for. Check the Off Trigger Delay box to enable the N3 to delay sending a wireless command after the sensor has reported unoccupied.
10. Click Next.
The port is now configured to receive and process contact-closure input from the occupancy or vacancy sensor.
Troubleshooting Unexpected Behavior
- Manually adjust the ultrasonic and/or infrared sensitivity settings on the sensor itself.
- Confirm that the sensor has been wired to the correct port on the N3 Satellite.
- Double-check your configurations in Design Studio.
