The MS-AT-7A-LV from Larson Electronics is a Motion Sensor that allows operators to add motion sensing functionality to
existing fixtures. This motion sensor can operate on either 12V DC or 24V DC and has a max amp load of 7 amps while
only consuming approximately 0.5 watts of power.
Low Voltage DC
Connect power to power supply outputting low voltage between
12-24
Volts DC.
This variable voltage allows greater versatility without affecting light output. Ensure
deutsch connectors are properly connected (If applicable)
.
INSTALLATION
Avoid installing where there is sunshine or constant air stream and temperature changes. Connect the lines according to
the right configuration. Wires are labeled according to input and output leads.
Use Only Low Voltage 12/24V DC for
both IN/OUT.
Mount motion sensor using the mounting ears on either side of the enclosure box. Plan a way for routing wires.
