Appendix D: Wire Requirements - Honeywell Fire-Lite Alarms ES-50X Manual

T-tapping of the SLC loop wiring is allowed for 2-wire (Class B) configurations. The total resistance of any branch cannot exceed 40
ohms. The total wire length of all branches cannot exceed 10,000 feet (3,000 m).
Connecting external system accessories to the ES-50X main circuits must be carefully considered to ensure proper operation. It is
important to use the correct type of wire, gauge and run length for each ES-50X circuit. Reference the chart below to specify wire
requirements and limitations for each ES-50X circuit.
Note:
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 exclusively employing electronic sounders instead of more electronically noisy notification appliances such as
electromechanical bells or horns.
2. The SLC can be programmed to operate in LiteSpeed mode (factory default setting) for a quicker device response time. While
shielded wire is not required in LiteSpeed mode, it is recommended that all SLC wiring be twisted-pair to minimize the effects of
electrical interference. Use the following table to determine the specific wiring requirements for the SLC when unshielded wire is
used:
Refer to Table D.1 on page 138 and Table D.2 on page 139 for wiring requirements.
