When single end of line resistor is used, any break in detector cable can be noticed.
When double end of line resistor is used, any break in detector cable and also short
circuit can be noticed. It is recommended to use double end of line resistor. 2.7kΩ
resistor that supplied with panel can be used for end of line connection. These
resistors should be connected to detector sides. It is wrong to connect the resistors
inside the panel as functional. If more than one detector contacts are wanted to be
serially connected, end of line resistor connection can't be made, none-resistor
connection should be made. Following picture shows end of line resistor connection
with tamper and without tamper.
