What Is A Eol Resistor

In this video were going to be using dscs rating which is 56k or 5600 ohms. End of line resistors eolr are resistors of a specified value that are used to terminate protective loops or zones.

End of line eol resistor value will vary from vendor to vendor.

What is a eol resistor. The purpose of eolrs is to allow the control panel to supervise the field wiring for open or short circuit conditions. Theres different ratings of resistors and even each panel will require a differently rated resistor. A resistor is just a device that impedes the flow of electricity without stopping it.

Determine the eol for your system. The end of line resistor is an ordinary resistor. End of line resistors eolr are resistors of a known value that are used to terminate protective loops or zones such as those found in esd or fg systems.

The purpose of eolrs is to allow the control panel to supervise the field wiring for open or short circuit conditions. To allow the panels internal ohmmeter to check the continuity of the wires supervise the wires the end of line resistor is at the end of the loop. Some lines end at the panel which means the resistor should be installed within the panel and some end at the last device wired in a parallel connection.

Advantages of end of line resistor. So what our resistors going to do is actually supervise the wiring. To allow the panels internal ohmmeter to check the continuity of the wires supervise the wires the end of line resistor is at the end of the loop.

For example fire alarm systems use the eol resistor at the last device hooked up in parallel on each line. Its purpose is to complete the circuit so the panel can perform a constant continuity check.
