LCM-320 and LEM-320 Loop Control and Expander Modules

LCM-320 and LEM-320 Loop Control and Expander Modules
LCM-320 and LEM-320
Loop Control and Expander Modules
• Up to 12,500 feet (3,810 m) on a Class B (Style 4) SLC loop
• Built-in degraded mode increases survivability.
• Very simple installation — plug-in style.
• Permits multiple loops in small enclosure.
The LCM-320 Loop Control Module and the LEM-320 Loop
Expander Module provide Fire Alarm Control Panels (FACPs)
with Signaling Line Circuits (SLCs). The IFC-640/IFC2-640
supports one LEM-320; the IFC-3030/IFC2-3030 supports up
to five LCM-320s and five LEM-320s. The LEM-320 module is
used to expand the IFC-640/IFC2-640 to a second loop, and to
expand each LCM-320 used on the IFC-3030/IFC2-3030 —
each IFC-3030/IFC2-3030 LCM-320 supports an expansion
Loop Control
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). However, the useful life of the system's
standby batteries and the electronic components may be
adversely affected by extreme temperature ranges and humidity. Therefore, it is recommended that this system and its
peripherals be installed in an environment with a normal room
temperature of 15 – 27°C/60 – 80°F.

Product Line Information
LCM-320: Loop Control Module. Adds SLCs to IFC-3030/
IFC2-3030; IFC-3030/IFC2-3030 supports up to five LCM320s and five LEM-320s.
LEM-320: Loop Expander Module. Expands each LCM used
on the IFC-3030/IFC2-3030; expands IFC-640/IFC2-640 to
two loops.
