Legrand LMPO-200 Outdoor Photocell Installation guide

Brand: Legrand

Model: LMPO-200 Outdoor Photocell

Type: Installation guide

Legrand LMPO-200 Outdoor Photocell is a daylight sensor designed to be used with a LMIO-301 DLM Photocell Input Module. It 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).

The LMPO-200 is a water tight, UV stabilized plastic with integral hood and has an operating temperature of -40˚F to 140˚F (-40˚C to 60˚C). It has a footcandle range of 0 - 200 fc and a peak current of 4.5 mA Maximum.

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).

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.

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.
