Connect the ELK-980 to the incoming phone jack using a standard 8 wire full modular "male to male" phone cord (J2). Connect the security equipment using a second 8 wire cord (J1). Depending on the equipment, this cord may be identical or it may have a male plug on one end and spade terminals on the other end. Connect two (2) wires from the ELK-980 to 12 Volts D. C. To power from 24 VDC, move Jumper JP3 to the 24V position. Connect two (2) wires from the relay output to the device that is to be activated when a dead phone line is detected. Option: Power and relay connections can be made using the four (4) extra wires in modular cord J1. This requires a cord with a male plug on one end and spade terminal wires on the other. This is not possible if the security equipment requires a male plug ended cord. See FIGURES 1 and 2 below for details on the various jumper options and wiring configurations. OPERATION A typical on-hook phone line will measure around 48 volts. The voltage is lower during a call in process (off-hook), however the telephone instrument will then draw current on the line. [. . . ] LED should return to 1 blink per second if phone line is OK.
