The GAI-Tronics emergency phone product line provides the flexibility to address a diverse range of
applications. A wide variety of functions can be achieved by altering the configuration data stored in the
phone’s non-volatile memory. These configuration options include:
•
Pre-programmed auto-dial telephone numbers
•
Call termination method (automatic or manual)
•
Maximum call duration
•
Answering options
Each of the above emergency phones require a “Class 2” 12 V dc regulated power supply (included) and
can be connected to any of the following:
•
Central Office (CO) line to the Public Switched Telephone Network (PSTN)
•
24 V dc or 48 V dc analog station port of Private Branch Exchange (PBX), Private Automatic Branch

Each telephone requires a dedicated power supply. Multiple telephones cannot be
connected to a single power supply. The power supply must provide galvanic isolation between its
input and its 12 V dc output. For dc-to-dc applications, galvanic isolation is required. Galvanic
isolation (separation) is achieved by using a transformer or opto-coupler.
