6.4.2 End of Line Resistant Connection
Using end-of-line resistance has advantages. When a single end-of-line resistor is used, a break in
the detector cable may be detected as sabotage by the panel. When a double end-of-line resistor is
used, both the detector cable break and the short circuit condition can be detected by the panel as
sabotage. Recommended to use double end-of-line resistor connection type.
The 2.7kΩ resistors from the panel packaging can be used for this purpose. These resistors must be
connected on the detector side. The connection of the resistors in the panel is incorrect because it
prevents the function from being performed. When more than one detector contact is connected in
series in the same Zone, end-of-line resistor connection cannot be made. Below are examples of
end-of-line resistance connections with and without tamper Connection.
Important: In order for the resistor connections to work properly, the resistors must be installed
on the detector side. Otherwise, the specified features will not work properly.
