Fault Isolator Module
General
The Fire•Lite 1300(A) Fault isolator Module is used with
Fire-Lite's addressable fire alarm control panels (FACPs) to
protect the system against wire -to -wire short circuits on the
SLC loop. The 1300(A) should be placed between each device
on the SLC loop to isolate a short-circuit problem between the
modules. It is required for true Style 7 operation so that other
devices can continue to operate normally in the event of a
short-circuit on the SLC.
Features
• Powered by SLC loop directly, no external power required.
• Mounts in standard junction boxes (4.0"/10.16 cm square,
2.125"15.395 cm deep),
• Integral LED blinks to indicate normal condition. Illuminates
steady when short circuit condition is detected.
• High noise (EMFIRFI) immunity.
Applications
The Fault Isolator Modules should be spaced between groups
of sensors in a loop to protect the rest of the loop. use to iso-
late short circuit problems within a section of a loop so that
other sections can continue to operate normally. The 1300(A)
supports a maximum of 25 devices in-between isolators,
except when using relay bases.
NOTE: LOADS PER RELAY BASE AND iSOLATORS11SOL4TOR
BASES: The maximum number of addressable devices between
isolators (or B22431A isolator bases) is 25 devices.

B224RB relay bases draw more current than other intelligent
devices. When calculating the 25-device maximum, B224RB rep-
resents 2.5 DEVICES; see example on page 2.
NOTE: ON MAXIMUM NUMBER OF DEVICES: See the SLC
Manual (51309) for irforma lion on loss of addresses due to current
limitations. Each module or base added reduces the capacity of
address positions in an SLC. All SLC field devices must have been
purchased after February 1995 to meet the aforementioned
requirements. it the SLC field devices were purchased prior to
February 1995, each isolator used reduces the capacity of an SLC
by two address positions. Requirements differ as applied to relay
bases; see note above.

• Dimensions: 4.5"H x 4.5"W x 0.25" D (11.43 cm H x
11.43 cm W x 0.635 cm D).
Construction
The face plate is made of off-white plastic. Module includes
yellow LED indicator that pulses when normal and illuminates
steady when a short is defected.
Operation
Automatically opens circuit when the line voltage drops belovi
tour volts. Fault Isolator Modules should be spared between
groups of addressable devices (maximum 25, see notes on
page 1) in a loop to protect the rest of the loop. If a short
occurs between any two isolators, then bath isolators immedi-
ately switch to an open circuit state and isolate the groups of
sensors between them. The remaining units on the loop con-
tinue to fully operate.
In Style 4 loops, the 1300(A) is generally used at each T-tap
branch, to limit the effect of short circuits on a branch to the
devices on that branch. The LED indicator is on continuously
during a short circuit condition.
The 1300(A) Fault Isolator Module automatically restores the
shorted portion of the communications loop to normal.
