Installing Modules in Frames
AlphaEcall™ 100 Series modules are designed for horizontal or
vertical orientation to allow various configurations.
The retaining clip for each module uses a pair of rectangular holes
in the frame, shown to the left, to retain the module.
The holes in the four corners of the frame are used to connect the
frame to the flush or surface back box with the (4) screws supplied
with the back box.
Push the tabs at the bottom of the module into the frame, position
the module, then snap the retaining clip into the appropriate holes.

Wiring ELM116 Modules
Attach all incoming selective “L” wires to their respective terminals.
Note
: Terminal #1 in the upper left corresponds to the upper left
label position from the front view.
Connect the
D
wire from the
AC219
to any one of the
COM (D+)
terminals and use the additional terminals to branch to additional
modules (if needed). This is the power in (+24VDC) for the master.
If running wires to additional masters they can be doubled up at
these terminals if necessary, but using junction blocks in a central
location is a cleaner way to do this. It is also an easier way to allow
troubleshooting and future changes if necessary.

Labeling the ELM116 modules
Carefully
pry the clear plastic lens at one side from the module
front and remove the paper insert.
Write directly on the paper insert or apply machine generated
labels in the white spaces provided.
When finished, put the paper insert in the lens cover and reinstall
the lens to the module using gentle pressure around the edges.
