The GAI-Tronics SMART Telephone 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
telephone’s non-volatile memory. These configuration options include:
Call progress detection, control, and call logging
Auto-calling, auto-answering, and auto-dialing facilities
Function inhibiting (e.g. tone pad and manual keypad dialing)
Maximum call duration
These functions are initially programmed during manufacturing and testing. After installation, they can
be programmed remotely via DTMF data call.
All SMART Telephones are line-powered and can be connected to the 24 V dc or 48 V dc analog station
port of Private Branch Exchange (PBX), Private Automatic Branch Exchange (PABX) or KSU.
Connection may not be made to pay telephone extensions or shared service (party) lines.
TMA users can schedule auto-dial maintenance calls to alert maintenance personnel of any unusual sensor
or fault conditions that exist. SMART Telephones can also be programmed to generate an auto-dial
maintenance call when certain sensor events are discovered. Access to the SMART Telephone’s
maintenance mode is restricted through the use of the maintenance access PIN. The maintenance access
PIN should be distributed only to trained maintenance personnel.
