INSTALLING THE EM14PS
The EM14PS photosensor is designed to be wired directly
to the EM1400 for single-zone outdoor lighting control
applications.
Connect the EM14PS to the EM1400MC input using two
1.
#18 wires. Note that the wires are polarized. If they are
reversed no damage will be done but the reading on the
display will show as 1024 and will not change.
Note that it must be wired to the Master Panel with the
2.
clock display. The slave panels do not have photocell
inputs.
Program per instructions in the EM1400 O&M Manual.

INSTALLING THE EMOPS1
The EMOPS1 photosensor is used with the EMPS3IN
card. This card sits on the data bus and allows for more
sophisticated control of light level triggers than that available with the on board photocell input of the EM 1408MC
or EM 1416MC.
Mount the photosensors in an appropriate location. For
1.
general controls they should be mounted on the roof
facing north. For areas that are shaded the photocell
should be mounted to collect the light level that needs to
be measured.
Connect the EMOPS1 to the EMPS3IN inputs using two
2.
#18 wires. Note that the wires are polarized and must
be connected correctly. One may run two #18 wires for
a distance of up to 1000ft. The wires must never be run
in the same conduit as high voltage wires. They must
also be kept at least 12” away from any parallel running conduit except when crossing the conduit at right
angles.
See EMPS3IN (Control Card) installation instructions on
3.
connection to EM1400 system.
