PLM2.8 - Phone Line Monitoring Option
The Phone Line Monitoring option by Janus helps you meet ASME / B44 2009 and 2010 code when used with our EMS model phones such as the PBX, PNB, PSS, PSL and PSM. This options adds an output to the phone that will close when it detects an issue with the phone line. This option should be used in conjunction with an LMA (Line Monitor Alert) device, sold separately. It cannot be used as a stand alone option.
