Wiring Resistors for Zone Termination Resistance
 To wire termination resistors:
• For RISCO EOL (end-of-line) and DEOL (double-end-of-line) detectors without
built-in termination resistance, install a 2.2K Ω end-of-line resistor at the
detector-side of each hard-wired zone
• For a detector with a tamper switch, you can use DEOL termination to save
additional main panel connections
• For RISCO TEOL (triple-end-of-line) detectors without built-in EOL resistance,
install 4.7K Ω, 6.8K Ω and 12K Ω resistors at the detector-side of each hard-
wired zone. TEOL is supported to identify detector masking and trouble.
