breakglass).
• Each control element requires a single 10kΩ end of line resistor. See above detail.
• If no fire alarm interface or smoke detector in system, leave 10kΩ end of line resistor in RM terminals "R" & "-".
If no RT 45 breakglass, leave 10kΩ resistor in RT terminals "T" & "-".
Detector Line fault - Flashing:
• Indicates line deactivated, press the 1/0 Reset button at top of panel to reactivate.
