If the switch is set to one of the other two settings, Kepri relies on the motion sensor to determine
when UV Emissions starts and stops: Expect a 15 second delay when the unit will power on or off
with the motion sensor.
Emission Selector is set
to
UV Emission Starts
UV Emission Stops
Always On
Kepri will continuously emit UV energy regardless of the status
of the motion detector.
On when Occupied
When motion is detected.
UV indicator is solid red.
15 minutes after motion is last
detected.
UV indicator is unlit.
On when Unoccupied
15 minutes after motion is last
detected.
UV indicator is solid red.
When motion is detected.
UV indicator is unlit.
Table 2 Emission Start and Stop
Presence Indicator
The Presence detection sensor increases device safety. This sensor detects IR radiation from a
human body, not movement, to identify when a person enters the UV emission area. The sensor's field
of view or coverage is focused at the most intense portion of the UV beam. The sensor will not cover
every portion of the room. Refer to
When presence is detected, the Presence indicator will turn solid red and emission stops until 30
seconds after presence is no longer detected.
When presence is not detected, the Presence indicator will be unlit and the UV emissions operate
according to the Emission Selector Switch as described above.
