360° High Bay PIR Fixture Mounted Occupancy Sensor (120-277V)
LS-YM2501APassive Infrared Technology: Motion sensor switch
provides hands-free operation by detecting a change in
temperature. Turn lights ON in response to the heat
generated energy (when a person enters a roon) and
OPFF when rooms are unoccupied.
The occupancy sensor is designed to mount directly
onto a luminaire and is ideal for high mounted areas
such as manufacturing facilities, warehouses, and all
other high ceiling applications.
Detects changes in the infrared energy given off by
occupants as they move within the field-of-view. When
occupancy is detected, a self contained relaw switched
the connected lighting load on. The occupancy sensor
is line powered and can switch line voltage. An internal
timer, factory set at 15 seconds, keeps the lights on
during breif periods of inactivity.
The best coverage area is between 15ft to 30ft mounting
heights. 15ft to 20ft radial coverage overlaps are lit by a
typical high bay fixture.The time delay adjustment
controls the amount of time the lights stay ON after the
last detected motion. Time delay can be adjusted from
15 seconds up to 30 minutes (factory time delay set at
15 seconds)
To decrease PIR detection range and sensitivity, rotate
the know counter clockwise. The detection range can be
adjusted from 100% down to 30%.
