End of Line Resistor Wiring Overview
① CAUTION: FOR SYSTEM SUPERVISION – FOR TERMINALS IDENTIFIED WITH A ① DO NOT USE
LOOPED WIRE TERMINALS. BREAK WIRE RUN TO PROVIDE SUPERVISION OF CONNECTIONS.
② Use Siemens TB-EOL terminal P/N S54322-F4-A2 or equivalent.
③ Use only normally open dry contact SWITCHES for the inputs
Figure 11 Wiring end of line and switch
·
Use a 4 or 2 pole UL/ULC recognized SWITCH.
· Switch Terminal must be capable of two conductors at one terminal.
· EOL Resistor wiring must be done according to UL 864 and ULC-S527, chapter ‘EOL Devices’.
· The EOL Resistors must be connected at the end of the input lines.
·
No addressable device or 2
-
wire smoke detectors can be connected to the inputs.
