Appendix A outlines the various circuits and devices that can be employed with the AM2020/AFP1010.

ECTION
Each of the various types of circuits within an AM2020/AFP1010 Fire Alarm Control System has a specific
type of wire that must be used in order to ensure proper operation. In addition, the wire gauge of a particular
circuit is contingent on the length of that circuit. To determine the specific wiring requirements for each circuit,
refer to Table A-1.
• If the SLC Loop is to be run in conduit with Notification Appliance Circuits, the risk of encountering problems can be
greatly reduced by using the LIB-200A or LIB-400 or exclusively employing electronic sounders instead of more elec-
tronically noisy notification appliances such as electromechanical bells or horns.
• In order to comply with the Federal Communications Commission (FCC) regulations on electrical energy
radiation when using the LIB-200, any wire entering or exiting the AM2020/AFP1010 cabinet that is not in
conduit must be of the twisted-shielded type. For termination of the LIB-200 SLC Loop shield, refer to the
Installation section of the manual originally supplied with the LIB-200.
