Telephone Line
Fault Monitor
ELK-980
APPLICATION:
The ELK-980 triggers a relay output upon sensing a dead telephone line. Circuitry monitors
phone line voltage as well as current in order to
protect against false sensing. It installs easily
between the incoming telephone block and the
equipment using standard 8 conductor modular
cables (not supplied).

Instructions Printed On Inside
INSTALLATION
1. Connect the ELK-980 to the incoming phone jack using a standard 8 wire full modular "male to male" phone cord (J2).
2. 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. (PHONE CORDS ARE NOT SUPPLIED)
3. 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.
4. 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. The ELK-980 utilizes both telco voltage and current to properly detect a
faulted line while reducing incidents of false detects. The ELK-980 considers the phone line to be faulted whenever the
line voltage falls below 3 volts and the line current draw is less than 18mA.
PHONE LINE OK STATUS LED blinks once per second as line is tested. Relay energized, contacts COM and NC are closed.
PHONE LINE FAULT - STATUS LED steady ON. Relay de-energized, contacts COM and NC are open, COM and NO are closed.
FAULT MEMORY Upon restoral of a phone line fault the LED remains predominantly ON and blinks OFF once every 3
seconds. To reset memory indication, momentarily short (for 2 seconds) the two small pins beside the
STATUS LED. LED should return to 1 blink per second if phone line is OK.
