GENERAL
The NOTIFIER ISO-X Fault Isolator Module is used with the NFS3030, 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, preventing 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.

CONSTRUCTION
The face plate is made of off-white plastic. Includes yellow LED
indicator that pulses when normal and illuminates steady when a
short is detected.
OPERATION
Automatically opens circuit when the line voltage drops below
four volts. Fault Isolator Modules should be spaced between
groups of addressable devices (maximum 25,
1
) in a loop to protect the rest of the loop. If a short occurs
between any two isolators, then both isolators immediately switch
to an open circuit state and isolate the groups of sensors
between them. The remaining units on the loop continue to fully
operate.
In Style 4 loops, the ISO-X 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 ISO-X Fault Isolator Module automatically restores the shorted
portion of the communications loop to normal condition when the
short circuit condition is removed.

ARCHITECTURAL/
ENGINEERING SPECIFICATIONS
Fault Isolator Modules shall be provided to automatically isolate
wire-to-wire short circuits on an SLC loop. The Fault Isolator
Module shall limit the number of modules or detectors that may be
rendered inoperative by a short circuit fault on the SLC Loop. If a
wire-to-wire short occurs, the Fault Isolator Module shall automatically open-circuit (disconnect) the SLC loop. When the short
circuit condition is corrected, the Fault Isolator Module shall
automatically reconnect the isolated section of the SLC loop. The
Fault Isolator Module shall not require any address-setting, and
its operations shall be totally automatic. It shall not be necessary
to replace or reset an Fault Isolator Module after its normal
operation. The Fault Isolator Module shall mount in a standard 4.0"
(10.16 cm) deep electrical box, in a surface-mounted backbox, or
in the Fire Alarm Control Panel. It shall provide a single LED which
shall flash to indicate that the Isolator is operational and shall
illuminate steadily to indicate that a short circuit condition has
been detected and isolated.
