resistance is 16.14 ohm/1000 ft. or 53.0 ohm/km.) The
R7404 Controller will accommodate up to 16 detectors.
The detectors can be located up to 2000 feet (600
meters) from the controller. Shielded cable is required for
the “B” (signal) leadwires. As with any field device,
shielded cable on all wires provides maximum protection
from RFI/EMI sources.
