Fire-Lite Alarms I-300 Isolator Module Required For Style 7 Class A H365R

$97.54 USD
IF_94AB31F6

Product Overview

The FireLite I300(A) Fault Isolator Module is used with FireLite's addressable fire alarm control panels (FACPs) to protect the system against wire-to-wire short circuits on the SLC loop. The I300(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 4-inch square (2-1/8" deep) junction boxes.
  • Integral LED blinks to indicate normal condition. Illuminates steady when short circuit condition is detected.
  • High noise (EMF/RFI) 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 isolate
short circuit problems within a section of a loop so that other
sections can continue to operate normally. The I300(A) supports
a maximum of 25 devices in-between isolators, except when
using relay bases.

NOTE: LOADS PER RELAY BASE AND ISOLATORS/ISOLATOR
BASES: The maximum number of addressable devices between
isolators (or B224BI isolator bases) is 25 devices.

B224RB relay bases draw more current than other intelligent
devices. When calculating the 25-device maximum, B224RB represents
2.5 DEVICES; see example on page 2.

NOTE: ON MAXIMUM NUMBER OF DEVICES: See the SLC
Manual (51309) for information on loss of addresses due to current
limitations. Each module or base added reduces the capacity of
address positions in an SLC. All SLCfield devices must have been
purchased after February 1995 to meet the aforementioned
requirements. If the SLC field devices were purchased prior to
February 1995, each ISO-X used reduces the capacity of an SLC
by two address positions. Requirements differ as applied to relay
bases; see note above
