When connecting

an LTEM

ary power,
ensure that the
power supplied meets the current requirements for the
configuration of modules being used.
Connection
to the control panel can be made using the terminal connections

or
a
previously
installed CDMAX or
GSMX4G 4
-
wire harness.


The chart below provides active current requirements for all configurations.
Current requirements for pre

Use the
worksheet below to add up the current for each device connected to the
control panel
auxil
i
ary power
.

After totaling
the current requirement for Keypads, Expanders, and Sensors, transfer
the totals to the Summar
y section.
Next, s
ubtract the total
s
from the panels auxil
i
ary power value.

Use
Chart 1 to determin
e

the current draw
the

LTEM
-
P in your configuration. Finally, subtract the
LTEM
-
P
Current

from the
Available Current
.

If the result is greater than zero, you may power the LTEM
-
P from
the con
trol panel.
