End of line resistors eolr are resistors of a specified value that are used to terminate protective loops or zones.

End of line resistor installation. Locate the and. So if you put the resistor at the panel its again only going to supervise the wiring between the resistor and the panel which is now wiring. Connect the end of line resistor cable supplied separately to the end of the 48v data line after the last fitting.

The resistor limits the current to a bare minimum so the panel doesnt think its detecting a fire but at the same time it allows the panel to confirm that current is flowing through all the wires. Thats why you need to put them at the end of the line and why theyre called end of line resistors. Failure to comply with the installation instructions can result in serious injury or death.

How to wire an end of line resistor step 1. End to end end of line resistor installation varied applications of end of line resistors while the primary purpose of eolr is to offer electrical wires constant supervision this semiconductor is used in other ways as well. Determine the eol for your system.

Locate the c no and nc markings on the alarm device. 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. Before getting into the importance of the end of line resistor though we have to understand the importance of having a fire alarm system in the first place.

Attach the resistor to the nc screw and the c screw if a fire. The 27k ohms value can be substituted with 22 kohms without any problem. The values 22 kohm and 47kohm are commonly used in the uk and some other countries.

End of line resistor thats where the end of line resistor comes in. Putting them at the panel is going to do nothing for you. The purpose of eolrs is to allow the control panel to supervise the field wiring for open or short circuit conditions.

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. Connect the end of line resistor data disruption fine tuning 512 dmx data check list a.
