Connecting loops
Loop guidelines
For best results, follow these guidelines when connecting loops:
• Install at least one isolator per loop (we recommend one for every 32
devices).
• Keep loop cabling away from high-voltage cables (or any other source of
interference).
• Star, stub, and T-tap configurations are not recommended.
• Install loop devices with a high current consumption as close as possible to
the control panel.
