Signaling; The Lib Signaling Line Circuit; Isolator Modules And Bases; Monitor Modules - Notifier AM2020 User Manual

The AM2020/AFP1010 communicates with intelligent and addressable initiating, monitor, and control devices
through a LIB Signaling Line Circuit (SLC). The Loop Interface Boards, LIB-200 and LIB-200A each control one
SLC. The LIB-400 controls two SLC loops. For XP and XP5 Transponders connected to SLCs refer to the
respective transponder manual (Refer to the Related Documentation Table in the beginning of this chapter for
part numbers).

Isolator Modules and Bases

Isolator Modules (ISO-X) and bases (B524BI(A) and B224BI(A))permit a string of intelligent addressable devices
and modules to be electrically "isolated" from the remainder of the SLC, allowing critical loop components to
function in the event of a short circuit fault (refer to Figures 4.5-2, 4.5-3 and 4.10-2).

Monitor Modules

Addressable Monitor Modules MMX-1 and MMX-101 allow the AM2020/AFP1010 to monitor entire circuits of N.O.
contacts, alarm initiating devices, manual pull stations, 4-wire smoke detectors, heat detectors, waterflow, and
supervisory devices. In addition, the MMX-2 may be used to provide power to and monitor conventional 2-wire smoke
detectors that are listed in the Device Compatibility Document (refer to Figures 4.6-2 through 4.6-6). The addressable
BGX-101L pull station provides point annunciation of manual pull stations (refer to Figure 4.8-2).
Control Modules
Through addressable Control Modules (CMX/XPC), the AM2020/AFP1010 can selectively activate notification
appliance circuits and Form-C output relays (refer to Figures 4.7-2 through 4.7-6).
XP5-C Control Modules
Each XP5-C Module allows the AM2020/AFP1010 to control a maximum of five individual circuits. The module
can be configured as a NAC/telephone or relay circuit. Its function is similar to the function of the control modules
described above.
XP5-M Monitor Modules
Each XP5-M Module allows the AM2020/AFP1010 to monitor a maximum of five individual circuits. Its function is
similar to the function of the monitor modules described above.
Intelligent Detectors
Through the SLC loop, the AM2020/AFP1010 communicates with intelligent ionization (CPX), photoelectric
(SDX), thermal (FDX), and combination (IPX) detectors (refer to Figure 4.10-1).
Loop Interface Boards Signaling Line Circuit
The LIB-200 and LIB-200A are single SLC boards. The LIB-400 is a dual SLC board. The capacity of each SLC
on a LIB includes up to 99 intelligent detectors, and an additional combination of up to 99 addressable pull
stations, and control and monitor modules. The AFP1010 will support a maximum of two LIB-400s (a total of four
SLCs). The AM2020 supports up to ten SLCs. One to five LIB-400s, or one to ten LIB-200s or LIB-200As can
be employed on the AM2020, depending on system requirements.
NOTE: In Canada, ULC Standard S524, for the installation of fire alarm systems, refers to signaling line circuits
as Data Communications Links (DCL). An NFPA Style 4 is equivalent to a DCLB, Style 6 to a DCLA, and Style
7 to a DCLR.
NOTE: If you are experiencing excessive noise on speaker or phone circuits in the IFC-1010/2020, the LIB-200
SLC polling signal may be the source. To reduce noise, connect the SLC shields to main panel power supply
system common of the MPS-24A, TB3, terminal 6, or use a LIB-200A/LIB-400.
