Hardware Installation—Installing the IFC-1010/2020
Notes: In Canada, ULC Standard S524, for the installation of fire alarm
systems, refers to signaling line circuits as Data Communication
Links (DCL). An NFPA Style 4 is equivalent to a DCLB, Style 6 to
a DCLA, and Style 7 to a DCLR.
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.
The Loop Interface Boards (LIBs) allow the IFC-1010/2020 to
communicate with the system’s alarm initiating devices and to control the
system’s output devices.
Through a communications loop
N25
(functions in accordance with the
requirements for NFPA SLCs or SLC loops ), the LIBs allow the control
panel to communicate with addressable pull stations, and intelligent
ionization, photoelectric, and thermal detectors. Through addressable
control modules (M5x0CJ/XPCXPR) connected along the SLC
communications loop, the control panel may selectively activate
notification circuits or Form-C output relays. Through addressable monitor
modules (M50xMJ), the control panel may monitor entire circuits of
Normally Open contacts, alarm initiating devices such as manual pull
stations, four wire smoke detectors, heat detector, heat detectors,
waterflow, and supervisory devices. M502MJ may be used to monitor
compatible conventional two wire smoke detector. Through Isolator
Modules (M500XJ), a string of devices and modules may be electrically
isolated from the remainder of the SLC communications loop, permitting
critical SLC loop components to function in the event of a short circuit on
the SLC loop. The LIB boards are power-limited.
The LIB-200 (refer to Figure 47) is a single signaling line circuit board,
which supports up to 10,000 feet maximum of field wiring for Style 4 and
up to 10,000 maximum for Styles 6 and 7 on Ports A and B. The
maximum loop resistance for Style 4 is 40 ohms on Ports A and B and
40 ohms total for Styles 6 and 7.
N26
If the wiring connected to the LIB-200 leaves the building it must be in
conduit. It cannot exceed 1,000 meters (10,000 feet), it must not cross any
power lines, and it must not be in the vicinity of any high voltage.
