This circuit will find applications in situations where several handsets share the same phone line. The FK319 is a line-powered priority switch so that when one handset is in use, the other phones are disconnected from the line. Each circuit module is a two line unit and may be used in tandem with other FK319 modules to accommodate additional phones. Connections to the other lines are restored when the first phone handset is replaced.
Power Supply: Line powered (no additional power is required)
Display : 2 LEDs used per telephone.
PCB Dimensions: 51.3 mm X 42.6 mm X 15 mm (2.02 X 1.68 X 0.6 in.)
