Legrand LMPO-200 Outdoor Photocell Installation Instruction
LMPO-200
Outdoor Photocell
for Digital Lighting Management (DLM)
INSTALLATION
Install the sensor on the roof of the building facing
north. The sensor housing is equipped with a ½" NPT
nipple and will thread into any suitable water tight box
or fitting. Orient the housing so that the hood is above
the lens to provide shielding.
SPECIFICATIONS:
MAINTENANCE
At least once every two months wipe the lens clean
with a non-scratching clean cloth. Check the housing
for damage and that no moisture has penetrated the
sensor, as this will likely render it inoperable.

DESCRIPTION
The LMPO-200 is a daylight sensor specifically
designed to be used in conjunction with a LMIO-301
DLM Photocell Input Module. The LMIO-301 converts
the 10 VDC signal from the photocell sensor to a digital
signal that is shared across the DLM Local Network.
The signal is forwarded as a BACnet object via a DLM
network bridge to the segment network for load control
via a DLM segment manager or BACnet compatible
Building Automation System (BAS).
