GENERAL
The NOTIFIER ISO-X Fault Isolator Module is used with the NFS-
3030, AM2020, AFP1010, NFS-640, AFP-400, AFP-300, AFP-200,
AFP-100 and System 5000 (equipped with an AIM-200 module) to
protect the system against wire-to-wire short circuits on the SLC
loops.
FEATURES
• Powered by SLC loop directly, no external power required.
• Mount in standard 4.0" (10.16 cm) square (2.125" [5.398 cm]
deep) junction boxes.
• Integral LED blinks to indicate normal condition. Illuminates
steady when short circuit condition is detected.
• High noise (EMF/RFI) immunity.
• Wide viewing angle of LED.
• SEMS screws with clamping plates for ease of wiring.
• Opens SLC loop automatically on detection of short, prevent-
ing the short from causing failure of the entire loop.
• Automatically resets on correction of short.
• Supports Style 4, 6, or 7 wiring.
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 ISO-X supports a
maximum of 25 devices in-between isolators, except when using
relay bases or IPX multisensors.
NOTE ON LOADS PER RELAY BASE AND MULTISENSOR
DETECTORS/ISOLATORS/ISOLATOR BASES:
The maximum number of addressable devices between isolators
(or B224BI isolator bases) is 25 devices.
B224RB relay bases and IPX-751 multisensor detectors draw
more current than all other intelligent devices. When calculating
the 25-device maximum:
• B224RB represents 2.5 DEVICES .
• IPX-751 in a standard base represents 12 DEVICES .
• IPX-751 in a relay base represents 14.5 DEVICES .
• All other addressable devices represent 1 DEVICE .
See examples on page 2.
NOTE ON MAXIMUM NUMBER OF DEVICES: Up to 100 ISO-X
modules and/or bases can be used per Signaling Line Circuit (SLC)
without loss of additional module addresses due to current limita-
tions. Each module or base added beyond 100 units reduces the
capacity of an SLC by two address positions. All SLC field de-

vices 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) .
