New silent knight 4875 dual phone line module, in box
Plugs into main 4820 control to provide connection to a second telephone line. It enables ring detection and line monitor functions for the second line. The 4875 “Smart Line†feature allows the 4875 to choose the unused line if one phone line is in use. If the system must report and the phone line(s) are in use, a tone is placed on the line so the user will know the system is about to go into a line seizure mode. If the 4820 built-in phone line monitor is in use, it will supervise both phone lines.
11 to 14VDC at 20mA (active only)
