» Labeling the ELM116 modules

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.

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.

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.
