PRIVACY DEVICE
Single Line Privacy
Model 41412 Modular Line Guard
| The Proctor Model 41412 Modular Line Guard can be used in the home or office to protect computer, facsimile and other types of data transmission devices from annoying and costly interruptions caused by other devices sharing the same phone line. Once a data device accesses the line, it is provided with exclusive use of the line until the transmission is complete. The module can also be used for voice privacy on single line telephone applications.
How It Works
The modular 41412 plugs in series with the line cord of each telephone or device to be restricted. If the module is installed on all extension lines in the system, the first phone device to access the line is provided with priority usage; all other extensions are restricted from the line. If the module is installed on just a few selected phone devices, the other devices not equipped with a 41412 are given unrestricted access to the phone line
