Electrical Specifications Wire Requirements
shielded wire for any non-SLC-loop wiring entering or exiting the cabinet that is not enclosed in
conduit. Use twisted-pair unshielded wiring for SLC-loop wiring.
NOTE: If running an SLC in conduit with Notification Appliance Circuits, you can reduce
problems by exclusively using electronic sounders (such as the MA/SS-24 Series) instead of
more electronically noisy notification appliances (such as electromechanical bells or horns).
