Module LCM-320 & LEM-320

LCM-320 and LEM-320 – Notifier
Loop Control and Expander Modules
Voltage: 24 VDC nominal, 27.6 VDC maximum.
Maximum loop length: The maximum wiring distance of an
SLC using 12 AWG (3.1 mm²) twisted-pair wire is 12,500 feet
(3810 m) per channel. For a twisted-unshielded pair, 12 AWG
(3.1 mm²) to 18 AWG (0.78 mm²):
– Distance with 12 AWG: 12,500 ft (3,810 m).
– Distance with 14 AWG: 8,000 ft (2,438 m).
– Distance with 16 AWG: 4,875 ft (1,486 m).
– Distance with 18 AWG: 3,225 ft (983 m).
– 50 ohms maximum per length of Style 6 & 7 loops.
– 50 ohms maximum per branch for Style 4 loop.
