Hardware Installation - Talk-a-Phone ETP-120 Series Installation & Operation Manual

2. Hardware Installation

Installation should be performed by qualified personnel only in accordance with the National Electrical
Code and other federal, state and local statutes and building codes. Using shielded cable is
recommended to avoid noise, hum, and other operational anomalies.
You will need a TS-10 Pin-in-Torx screwdriver or bit to complete this. If you do not own one, you may
purchase one from your local industrial supply store or from Talkaphone. Contact your Talkaphone
distributor for purchasing information.
Talkaphone Model FM-110 and Model SM-110 are designed to accommodate the ETP-120 Series
Analog Call Stations for flush mounting and surface mounting, respectively. Contact your distributor or
Talkaphone for more information.
1. Plug the RJ11 connector on the cable assembly into an RJ11 receptacle that is terminated to an
analog phone line (red is ring, green is tip). The RJ11 connector is terminated on a cable harness
that routes back to a small 2-pin connector located near center-right on the circuit board (see photo
below).
