Notifier LEM-320 Loop Expander Module - NFS-640, NFS-3030 Fire Alarm FACP Boards
Description:
The LCM-320 Loop Control Module and the LEM-320 Loop Expander Module provide NOTIFIER’s ONYX® Series of Fire Alarm Control Panels (FACPs) with Signaling Line Circuits (SLCs). The ONYX® Series NFS-640/NFS2-640 supports one LEM-320; the NFS-3030/NFS2-3030 supports up to five LCM- 320s and five LEM-320s. The LEM-320 module is used to expand the NFS-640/NFS2-640 to a second loop, and to expand each LCM-320 used on the NFS-3030/NFS2-3030 — each NFS-3030/NFS2-3030 LCM-320 supports an expansion LEM-320.
Specifications:
- 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.
- Maximum current: for LCM-320: 130 mA; for LEM-320: 100 mA; for single SLC loop: 400 mA maximum. NOTE: Maximum short circuit — loop will shut down until short-circuit condition is corrected.
- Maximum resistance: 50 ohms (supervised and powerlimited).
- Temperature and humidity ranges: This system meets NFPA requirements for operation at 0 – 49°C/32 – 120°F and at a relative humidity 93% ± 2% RH (noncondensing) at 32°C ± 2°C (90°F ± 3°F).
